Hope I can help you guys in fixing your E74 errors

Thank you for the Xbox 360 repair tutorial I really appreciate what you did jimwross but unfortunately the images or what are not displaying it would be better if we have a picture of what your are mentioning in your steps so we can follow it. Also, as what I mentioned in my previous posts. Here are some key points to remember when fixing your Xbox 360. Keep these in mind so you will not do more damage to your precious console

I wouldn't suggest this but I figured what the heck.  Stripped everything down cleaned chips under heat sink.  I didn't have a heat gun or hairdryer so I used a hot butter knife that I bent the tip on.  Just heated the knife on the stove and when it got hot placed it on chip and think I could actually hear it re-flow the solder.  Plugged board back in and the thing booted up no more E74 smile.gif

Have  one I fixed for a little bit with the xclamp fix and I might try this to see if I can bring it back to life.  its way more dead though worth a try.

Wish I could have my Error420 nick sad.gif


lol omg so your butter knife was at least 700 degrees then, im guessing you used welding gloves to hold it

solder melting makes no sound, unless your superman

The images from the start of this thread are unavailable for me. Does amyne have images of what needed to be heated? I recently got the 74 error. Did the standard rrod fix and it worked for about an hour or so then the image got lines in it and now it's back to the e74. I don't mind using a heat gun but want to make sure i am using it in correct areas and for the correct amount of time. Any help would be great.

E74 Will most likely need a gpu replacement. Just send it in to one of the many pros on this site.

Hi,
already did this twice,xbox came back to life and now E74 again! The second time the error appeared i barely played a game.Let it load and after a couple o minutes strange lines on the screen.Switched off the console,powered it on again and BOOM, E74!

So i guess i m not reflowing at the right place or not heating it as much as i should.
Is 375�C enough (5-6 cm above the marked area) ? Should i heat it for more than 4 minutes?
Both times i let it cool for like 10-20 minutes before reassembling the whole thing back.

Thanks in advance guys!

you guys are having a lot of problems. The xbox 360 phat(non jasper) was designed bad from the get go. get the right reflow / reball equipment. And, no, youtube videos dont' help. The people who put youtube videos on xbox 360 reball/reflow are leaving something out. They don't want their secrets to be let out. Because if they did let the secrets out there would be other would be DIY fix people out there.

Either learn through a certified training center, and do it yourself. Or send it to a pro with lots of feedback. Just don't watch youtube and think you can learn something from it.

this is precise stuff. and shitty equipment and wrong types of chemicals mess it up. Especially if you have had it worked on before. It's just not worth it imho.

Alright! So roughly six months ago I was ripped off by a guy on Craigslist, I bought a 360 from him got it home to find the E74 errors.  I eventually just bought a new one, and was out the cash as I could never find the guy again.  I was never able to find legit information on the E74 problem beside the fact that it more then likely dealt with the ANA / HANA chip.

After fixing hundreds of 360's now, I thought I'd post my little solution for the E74 problem.

----

What you need:

Stuff to open the 360
Basic X-Clamp replacement stuff (follow the other tutorials on how to do this)
Heat gun
Patience

----

Ok so here we go:

IPB Image
My workspace

IPB Image
The E74 Error on the current box

IPB Image
Heres the box with the problems

IPB Image
Case off, remove all of the screws, including the little black ones on the RF unit and for the x-clamps

IPB Image
Unplug the SATA and DVD power cables, unplug the fans

IPB Image
Now we have a good look at the chip cuasing all of the problems.  Sits directly above the GPU.  It's the video scaler chip aka ANA / HANA chip.

IPB Image
And another photo of it

IPB Image
here's a view from the bottom

IPB Image
And another view

IPB Image
Close up of the ANA chip

IPB Image
Here's my el-cheapo heat gun, you can pick up one in the paint section of lowes or home depot.

IPB Image
Heatgun box

IPB Image
Remove the X-clamp from the GPU, take the bolts out of the heatsink

IPB Image
I like the goo gone gel, it works wonders for taking off the stock heatsink goop.  Just make sure to clean the area with rubbing alcohol afterward.

IPB Image
Clean the GPU off

IPB Image
Clean the heatsink off

IPB Image
Use the higher percentage rubbing alcohol

IPB Image
Apply artic silver, do the standard X-Clamp fix.

IPB Image
Now the parts we need exposed (underneath the stock x-clamp) are accessible.

IPB Image
OK, so put your heatgun on a medium setting and start apply heat to the marked areas. KEEP THE GUN MOVING you don't want to burn the parts.  This will cuase the solder joints to reball themselves (hopefully). Concentrate on the area linking the GPU and the ANA chip.


IPB Image
The motherboard is going to be HOT. Let it cool down.  Put the fans and the fan shroud back in, and test it out.

IPB Image
Woohoo!

IPB Image
Nice.

Now if this doesn't work the first time, don't fret.  Keep trying, you may need up the heat on your heat gun or give the board more exposure.  After you get the 360 running,

keep the case off for a bit, play a few games and see what happens.  Some 360's are worse off then others, and may require you to go through the steps again (if the E74 returns).

Do you know the solution on how to fix the E73 error?


This has to do with frying the ethernet chip, usually from people doing the stupid towel trick and overheating components that were not supposed to be hot.  You could replace it.

You should cover any exposed parts that don't need to be heated with aluminum foil (lots of it), such as cylinder capacitors, fan socket, eject and sync buttons, etc. There are already a bunch of heat gun threads on these forums.




Title: Tutorial: Fix E74 / No Video Errors
Post by: Wilhelm_I on April 07, 2008, 07:07:28 AM

Nice tutorial I have been kind of doing the same with my E74...
At first I tried to take pressure on the ANA-chip with a stack of cents this didnt work for long so I heatgunned it and since then it works again...
However I must critisize something which just came to my mind, I guess doing the X-Clamp replacement and applying arctic silver before heatgunning it is a bad idea.
Well, why?

Arctic silver is only supposed to be used up to a maximum heat of 120�C which is easily reached if you want to soften the solder(to reflow it you need a 225�C I guess). I am not sure in which way it changes the way the thermal compound operates but I guess it will rather harm than do any good.
As you dont completely reflow anything the X-CLamp replacement should be quite OK but if you do actually really reach the melting point of the leadfree solder, the pressure will push the whole GPU onto the mainboard which would destroy the solder balls and flatten them-> The mainboard would be trash...

Apart from this the tutorial is very detailed and helpful, maybe you can edit this




Title: Tutorial: Fix E74 / No Video Errors
Post by: brandogg on April 07, 2008, 07:10:28 AM

Wow, I didn't even notice that. You should never heat gun your board when the heatsink is on the chip, and you should also be heating the underside of the board as well as the GPU itself.




Title: Tutorial: Fix E74 / No Video Errors
Post by: jimwross on April 07, 2008, 08:07:17 AM

Ok yeah, I guess it's always just worked for me so I haven't even thought about that!  jester.gif

My reasoning on this was the following:

1) The problem which seems apparent to me is that the connection between the GPU and the ANA chip comes undone cuasing the E74 error.

2)  Just as with the X-Clamp fix, the connections themselves seem to appear unneath where the previous X-Clamp was

3) With the re-applied pressure of heatsink on the GPU being pressed down w/ the machine screws it would hopefully hold the parts in place WHILE its being re-heated.

I just have a feeling that its the actually more to do with the GPU's incomplete connection to the ANA chip that cuases the E74; I've noticed after people overheat the GPU or get the 3 RLOD the E74 becomes much more prevelent.  In addition to this, I have a hard time buying that the ANA chip gets hot enough to break solder joints (thus proving the penny method is sort of inapplicable), leading me to believe the problem area is that of the connections UNDER where the previous x-clamp was.

I could be totaly off base, just some assumptions I made. Thanks for the input.  Brandogg, any ideas on this?  I havent had anybody else to bounce stuff off of.

I would venture to say most ANA/HANA problems are caused as you described them, GPU-side. I fixed a no-video error using the heat gun as well, and never went anywhere near the ANA chip on my board with the heat.




Title: Tutorial: Fix E74 / No Video Errors
Post by: [AD] on April 07, 2008, 04:10:43 PM

How long do you heat the area up for?






Title: Tutorial: Fix E74 / No Video Errors
Post by: brandogg on April 07, 2008, 09:31:32 PM

Not very long. Maybe 1 minute altogether tops - the idea is that you gradually heat up the board, just don't go blasting 1000F right away. First heat the bottom of the board, moving the gun in small circles  or waves, slowly getting a little bit closer/warmer, then do the same to the top - first around the GPU, then on the chip itself. You need to keep the system still while you do this - place it on some type of rack or between 2 chairs or something so you can quickly switch between the top and bottom of the board.

e74 has nothing to do with the ana/hana chip. i have fixed it everytime (100% of the time) by reflowing the gpu.

Well, you got lucky then, in my case it was definitely a pin of the ANA-chip which lost contact because pushing it onto the mainboard made the 360 boot...
When I moved my finger away the screen got weird artifacts over the whole screen and the color changed slightly
And I did not take it under enough pressure to make the GPU balls get contact again(nothing like the penn-fix or so) and I did the X-Clamp replacement like 2 month before which fixed it the first time.
So it might have been the GPU in the first place but it was definitely the ANA-chip when it failed the second time...

I think its been pretty well established that the E74 Error has to do with the connection between the ANA / HANA / failure of the Scaler Chip to the GPU

You'd have to figure out how to attach it too... but I don't think its the ANA chip thats really getting to hot, i'm fairly certain its from the GPU getting really hot and melting the connection between the two...

Nice tutorial, Anyone know where to get a ANA chip heatsink from?

I used these they are perfect for the whole mainboard...
There are 8 in each pack.
I put one on each RAM block and one on the southbridge and combined 4 of them to "build" a bigger heatsink that perfectly covers the ana-chip
They are cheap and work very well.
I bought my copper heatsinks for 2.90€ which is approx 5 US$ aluminium costs a bit less

OFF is better as the thermal compound cant be used for temperatures higher than 120�C and if you heat it up too much the pressure might flatten the solderballs below the GPU which would wreck it, on the pictures he had them ON though

Kewl.  Thanx  biggrin.gif

On another note, I am glad to see confirmed that using Goo Gone is a good thing.

One of the hardest part of doing the 3RROD fix (at least for me) was the finger-breaking cleaning of the old Heat Sink compound using alcohol.. I came across a little can of Goo Gone Extreme in my wife's cleaning cupboard.  What took me almost 20 mins to do with alcohol, I can do in 2 mins with the Goo Gone.  And the results are 20 times better..

My only concern was that the strong cleaner in the Goo Gone might harm the structure or the circuitry of the GPU and CPU.  But I haven't seen any thing like that.  Knock on wood..  biggrin.gif


Thanx again.

Hi I am very interested in this method as I think it will solve my e74 error that has been troublesome to fix.

I was just wondering approximately what temperature the board must reach for this to work and what temperature would be TOO much?  I have a heatgun but I think I might pick up an infrared thermometer for doing this.  Thanks for any input

You just need the temp to get hot enough to melt the solder points, mine has two settings, both work, you just have to be careful to keep the gun moving so it doesnt burn the board / other parts.

I fixed my second 360 using this method it works very well
I started using my heatgun with the lowest step which is around 300�C to "warm" it up...
After like a minute I switched to 500�C and did this another 2-3 minutes
When you see the capacitors shaking you can decrease the temperature to 300�C and let it cool down for half an hour.
After it cooled down the solder of the area looked a bit different it had a yellow/golden shine
I did this twice once for the upper side and after cooling down the bottom...
360 works flawless, I will keep you updated

Wow, if your solder turned yellow, you probabley heated it too much - solder will still conduct in this state, but it is inhibitted somewhat... just my two cents... smile.gif

I just wanted to make sure that everything was liquified.
However it is quite hard to figure it out as you dont really see it when it does, the only sign is that the capacitors either start smoking or that the capacitor shakes when you move the heatgun.
This xbox was a quite hopeless one anyway so I didnt really have anymore I could do besides the oven trick but now it is working and will hopefully never die again

The caps started "shaking"???

That's my biggest issue with the Heat Gun.. I never know how much is enough.  I am always worried about frying something, so I am pretty sure I use it too little..

What I have done is to use my heat gun (WAGNER Model #0283015 one setting  ON) about an inch or so off the  MB, using circular motions and concentrating on the selected area of the MB (NIC area for E-73, Ana/GPU for E-74, etc etc)..

But it has never fixed the problem..

So, you say I should look for the caps to start "shaking".. Could you give me a bit more detail??

Thanx

I used the heatgun in the same way as you but I warmed it up with the first setting and switched then to the second(500�C)
Well when the solder melted the capacitor is kind of swimming in the solder and as you are moving the heatgun around the whole time it kind of vibrates and slowly moves a bit because of the airflow.
You can compare it to a ripple of water when you blow at it...
You gotta stop then because otherwise it might move too far and then you will have to put it back in place...
it really takes a while so be patient and keep watching the bigger capacitors...
I guess I overdid it though because the color of the solder changed so be careful.
When I get my next E74 I will record a video...
The area depends as well putting pressure on the ana-chip fixed my first 360 so I concentrated on the ana-chip which fixed it.
This one was different though nothing brought it back to life so I heatgunned the area from the whole anachip over to the GPU from both sides.
After that it worked finally smile.gif

That's essentially what I did - I heated the ANA chip and both side of the GPU, using circular motions about an inch or two off the board.  I used alot higher setting than you guys did however - my heat gun goes anywhere from 300 - 1350C - I switched mine to the 1200 setting and only hit my board with it for about 1 minute total time between both sides of the GPU and the ANA chip - make sure to KEEP THE GUN moving or else stuff will fry - I never waited to 'see' the solder melt, I just assumed it would and that 1 minute at that high of a setting would be more than enough.

My settings may have been overkill, but you want solder to only be heated for a small amount of time or the discoloration will occur, so I pretty much just guaranteed that I could bring it up to melting temp very quickly.

...again, just my two cents.

Good luck everyone!

1350C?! That's insane! That kind of heat would destroy just about anything in it's path. Anyway, make sure you cover all the capacitors, eject/sync buttons, fan header, etc, with several layers of aluminum foil.

Yeah that sounds outrageous doesn't it?  I was in a hurry typing yesterday - I meant 1350F (which I believe is something like 732C or somethin like that).  If it was 1350C the gun would more than likely melt in my hand and cause me to spontaneously combust smile.gif So the 1200F setting is about 648C.

Sorry for the typo smile.gif

I told my brother how to do this over the phone to fix his xbox.

It already had the xclamp mod that I did to it... So took off the heatsink of the gpu and tin foiled around everything except the blue area in jimwross' picture below:

IPB Image

He had an old heat gun that only had low or high setting so I told him use low.

He heated in circular motions around the blue but focused most of the time on the red square, all for a total of 3 mins.  Hooked it back up after an hour and it works!  Did not need to heat the top.

Thanks everyone I think this is the best fix for E74 errors!!!  Hairdryer on ana chip is only temp fix

If I did it I would have taken pictures but I only told how to do it over the phone so I don't have any, sorry.  sad.gif

Does anyone know if this will work for error codes like 0020?  In theory it should work since blasting the bottom of the board with the heat gun would reball the solder, but has anyone used this tutorial for any other general 3RLOD error codes?

I have that error code and I cant seem to get rid of it with the x-clamp or the penny fix. How did you go about using your heat gun on your 0020 360?

Hello everybody.  A few days ago I was playing and everything looked...not fuzzy, but choppy...not sure how to describe it.  A day after that I got the E74 error, and my next few tries turning it on kept turning up the E74 error.  Then, something else happened, it would start up like normal, but with a blank screen.  After about 30 seconds, the fan would get louder, and louder, and louder, until the xbox over heated and the fan shut off(which doesn't make sense really...that should be when the fan gets louder) and then the only thing to do was turn it off and google the problem.  Would this possibly fix that? or should I get a new AV cable or something?  SHould I try the RROD fix?(already done it once before a few months ago actually)

The chips dont have good contact with the chip dies, this can be cause by too many/few washers and too much/not enough thermal compound(size of a rice grain is perfect)
as the fans get louder it will for sure be the cpu heatsink as the cpu regulated the fanspeed.
If this doesnt fix the overheating issue you will have to do the same procedure for the GPU heatsink.
The E74 is a pretty weird error it might happen that you keep turning your 360 on and off and after like ten tries it boots up but the screen is covered by artifacts and the colors change until the screen is nearly black...
It can be caused by a faulty av-cable according to the faq but if you can see the E74 error message on the screen your av-cable will be fine.
So it will either be a pin of the scaler chip that has lost contact or a broken trace between the gpu and the ana-chip.
Just follow this tutorial it will fix it but make sure that you remove the gpu heatsink and the termal compound before doing that and that you isolate the capacitors in the area as they will blow at this high temperature.

I still can't seem to get this right..

Basically I am looking at two choices now...

Take a totally fracked up MB and use the Heat Gun on it until it melts or catches fire or whatever.  This will show me exactly how much heat the MB can take.  I know that paper burns at 451f (thanx to Ray Bradbury.. biggrin.gif)

Another, less destructive option, is to pick up a Infrared Thermometer and get the chips/MB up to the required temp..  If I go this option, what would the desired temp be??  I also see reasonably priced Infrared Thermometers that measure up to 1000f.  Would that be sufficient??

Thanx

If you have replaced the X-Clamps try loosening the screws.  The way I always trouble shoot this problem is the following:

1) Take the motherboard out of the metal case
2) Hook up the DVD drive and the RF / Power button board
3) Turn it on

If it doesnt give you the 2 Red Lights / Fans speeding up and turning off, then you know has something to do with loosening / tightening / mis-allignment of your x-clamp fix.

SO when you re-assemble the box, try putting the board back in to the metal case and leaving out the two middle LONG screws that attach the top plastic piece.  For whatever reason this seems to help if you get a stubborn 360 that keeps doing the 2 red light thing.

Hope this helps.

Hey.

You will start to notice slight colorization on the solder points (goldish color), thats how I tell when its good to go.  The board can take quite a bit as long as you don't get it close to the stuff that can melt / be destoryed (capacitors and plastic pieces), you really don't have to be over-cautious with it.

The chips dont have good contact with the chip dies, this can be cause by too many/few washers and too much/not enough thermal compound(size of a rice grain is perfect)

Agreed.  I wish i could edit my original post and change the heatsink thing around.

Oh well

The desired temp is a little bit higher than the melting point of the leadfree solder that they used which is 217-218�C(422.6-424.4�F)

I have had the E74 error for a few weeks now. I didn't know there were user fixes for it before now.

I started to notice problems while playing a game rental, fairly scratch tbh and was getting Unplayable Disc errors, I would have to open and close the tray a coupel of times, on each gaming session for it to boot. The following day when I was playing I had weird squares and couloured stuff pop in on my screen, it locked up I reset it and have had the E74 message displayed ever since.

It is highly unlikely to be the AV cable, I have both a VGA and Component cable and have tried them both with the same result.

I've been recommended to checkout the X-Clamp and airgun fix (will a larger hairdryer do the trick btw?), but just wanted to outline the issues before the problem appeared, just in case there is something else worth considering...

I mentioned this problem on a nother, though not so technical forum and was recommended to replace the DVD drive as it was believed to be casuing the E74 message. Someone else promptly jumped in and claimed that was not possible and recommended me to here.

If I can get it back up and running before the release of Grand Theft Auto IV, I'll be well chuffed. I have no experience with this sort of thing though. pop.gif

I had those weird squares and lines then e74 after reset... and heating the ana chip with a hairdryer only fixed my xbox for 1 day.  Hairdryers have a safety cut off switch at 140F (60C).  This only expands the solder to allow play for a day or so until it cools back where it was.  You need to reflow the solder using this guide (remove the gpu heatsink) using a heat gun.  As has been stated before, the lead free solder melts at 423F (217C).  I only had to heat gun the bottom side.  Please follow the first post by jimwross but remove the gpu heatsink before heat gun.

Yeah, that all sounds rather too much for me. I'll read it over and try and familiarise myself with the process though.

If it is the scaler chip, which can be determind by applying pressure to the chip then booting, and if it works at that point, then this confirms it is the scaler chip. Is it not just possible to somehow keep that pressure on the chip at all times once the case has been put back together, or is it really necessary to gut out everything and get a heatgun going?

I am thinking of putting the 360 back in its original white casing, and sending it off to MS and hopefully they just replace it without question for me. I suppose worst case scenario is that they send the console back to me not fixed if they notice the warranty seal has been broken.  wacko.gif

The whole reliability fiasco has really gotten me on a downer though, this is my 4th console, and I always wanted a black one to match my gear. I hanged on for ages and after 12 months of owning it I decided to replace the case, some 5 months later I get this problem.

Don't mention fraudulent warranty repairs, and don't attempt them either. You made the choices and threw your warranty out the window.

Please only attempt the heat gun fix, if you've A. got nothing to lose, and B. watch some videos and take your time. It can work if it's done right, but if done wrong it can absolutely destroy your board.

Yes, I'm going to have to try it out by the looks of it. I'll have a look and see if I can find a heat gun to order online now, hopefully they're not too expensive.

In regards to your warranty statement, I can understand such things should not be discussed on the forums. My point or more frustration is waiting for well over a year to try and make sure the console would not fail, after that I then persued the case replacement. So I'm sure at the very least you can understand my frustration. I should have just gone with the tacky black faceplate, shouldn't I lol

I'll post back soon, first of all I'll try adding pressure to that scaler chip mentioned and see if it boots, then post back here once I've had chance to try it out.

Don't ever bake your system again. That low of heat won't reflow the solder, but it will overheat just about everything in the system - also, if it were to get hot enough, you'd probably end up with foil stuck to the bottom of your motherboard.

You may be right but i think your wrong when your using a heat gun thats a hell of a lot hotter than a 200 degree oven the only components that may be affected are the caps and their more than likely solid so if you haven't tried it yet explain to me why it been running for over a week already maybe a fluke? i don't know but if it works for two or three months till the new one comes out i'm still ahead everything else lasted only a day if that and thats only an hour i've been playing for three or more hours

You need to heat the solder up to more than 219�C to reflow it.
you only heated it up to a max of 200�C which only softens the solder a bit.Your 360 might be fine now but it will more likely get rod again than an xbox which was reflowed.
The oven trick should only be used as a last resort and if you choose to do it you should at least do it right...
With the heatgun you can direct the heat right at the area which is assumed to be causing the issue which might not always be as efficent as the oven trick but at least you dont have to bother that much about blowing some of the larger capacitors.
When you see smoke coming from one of the capacitors you can just move the heatgun away and replace the component but when it starts smoking in the oven it will already be too late.

Maybe so but you should know that if the oven is set at 200 it could have been higher my guess it could have went to 250 i never checked temp all i know it was higher than 200  the purpose of the foil enclosure was to hopefully increase even heating of all joints across the m/b also i want to add the heat exhaust is a lot cooler than before ie not as hot it used to blow out hot air now more warm than hot

Instant re-heating doesnt have to do with the ANA chip.  Loosen up your machine screws a bit see if that helps.

well
did you put it into the oven with the heatsink installed?
If so you can be pretty happy that your 360 is working at all as it would have pressed your gpu onto the mainboard if it actually would have reached the melting point...
The fact that the exhaust air is not hot but warm is that you completely fried the thermal compound which doesnt conduct heat properly anymore(max temp 120�C)
If you didnt have the heatsink installed while baking it in the oven you must have done something wrong during the installation of the heatsink as the heat isnt transfered properly to the heatsink.
The cooler the heatsink is the hotter is the chip below....
The foil was actually a good idea as it isolates the components from the direct heat so this might have prevented components from getting too hot. Though this was not your intention
I also doubt that the oven gets up to 250�C when it is set to a 200�C
Check your solder for a golden glance if you see a golden glance you made it to reflow it...

               A blow dryer isn't hot enough to reflow solder, your errors will probably be back soon.  To to the who baked his system - is that 200F or 200C? 200C (or even 250, if it may have been that hot) could possibly get some results, but it's still a very bad idea. When I use a heat gun (or used, rather), I isolate the GPU, putting many layers of foil around all (non-SMD) capacitors, exposed switches, etc, so only the necessary parts are heated (GPU and sounding/underside areas). Also, the heatsink *must* be removed or you can have the sink basically squash the GPU down in place, bridging many or all solder below it. You'll also need to replace the thermal paste afterwards, since the overly excessive heat will most likely ruin it.

no i didn't i removed everything from it though i might have done well to leave it attached to the metal  chassis seeing that the m/b layer thickness is shit then after it cooled down take it off and attache heatsinks and then reattach to chassis If it was the thickness of a real m/b i doubt anyone would have problems the m/b is so warped it pathetic i never reattached to chassis only top cover attach and snapped together

               Well my E74 UMM i used an electrial oven and a Ktype thermalcouple to measure the temperature on the board surface

What i did was try to simulate a reflow oven ( i had to use alot foil to protect the caps)
any way just to get you started i didn't get the E74 error fixed but i didn't damage the board anymore i think either

when the board surface reached about 200C i started a one minute timer and then turned off the oven and starting cooling the board about 3-4C/s

anywas i think i got close to what a reflow graph looks like but i didn;t fix the E74 i think i didn't fix it becasue my E74 lies with the ANA chip i insulated the ana chip from heat when i was doing this


So i have two thinks try and ""reflow"" and HOPE i don;t damage anythink this time aroudn again with out insulating the ANA chip or the south bridge

OR SWAP the ANA chip

which one do u guys think i should do

OHH the board still give E74 or ht i can do is place the heatsink on top it not screw it down just place on top and heat the board to around 180C that non melting point for unlead solder but it will get every think loose enough to touch back i think

ANY ideas

When you do it the next time heat it up to 230�C this is 10�C more than necessary to melt the solder and should definitely work...
make sure you isolate everything except the area from the whole gpu to the whole ana-chip.
Remove the heatsink and thermal compound from the chip, as it will otherwise press the gpu onto the board which will flatten the solderballs...
heating it up to less than 219�C will only fix it temporarily when it gets hot enough you got the same error again...
Maybe you should invest some money into a heatgun this will only heat up the area that you want to heat up
Swapping the ana-chip is not an option either as I dont think that the chip itself is fried

I think its been pretty well established that the E74 Error has to do with the connection between the ANA / HANA / failure of the Scaler Chip to the GPU


Yeah I think your dead on. After I got my replacement arcade I have been working with my old system. I knew from the start it was most likely the scalar chip, or the connection between them.

When I pulled it apart and looked how the fan cowling directed hot GPU air directly over the chip and the traces between them.

Explained to me why covering the exhaust for a bit while playing would reverse the discoloration which was the first symptom. When I removed the block and the fans spun up and quickly cooled the board the discoloration came right back. Also explained why I didn't see any symptoms of an overheated GPU, or damaged GPU ram which almost always show up as geometry artifacts and not a specific discoloration.

I made sure the GPU was seated and put better, as well of a lot less thermal compound on just the GPU heat sink.

Last thing was I grabbed a blow dryer and pre-heated the bridge between them just to see if it was the problem and I got it working fine until I threw the fan cowling back on and it cooled down. I have a heat gun, but I am reluctant about how much heat, how long, and how to orient the main board while I do it. Start small and work my way up I guess.

I cant promise anything but I guess it is the scaler-chip in your case as well...
I got an xbox that sometimes got E74 and when I kept turning it on and off it started up without the 1RLOD every once in a while(like 5-10 tries usually)
However this no video issue could also be the gpu...
So just put pressure on the ana-chip while booting or try what the other dude found out(nice investigation by the way)
If it boots then it is the connection of the ana-chip to the gpu...
Otherwise it might rather be GPU related then you will have to do the x-clamp fix penny fix or what so ever there are several fixes for this ceratain error(imo the X-Clamp replacement is the best besides a reflow though)

               hey.
i have the no video problem also with no 3rrod i tried the x-clamp fix and nothing it only works for about 5 to 10 minutes if i let it overheat, so i guess its some solder that is ruined, i've applied pressure on the mentioned chip and it doesn't give me image, so it must be the gpu am i right? it never gave me the e74 error by the way, just lost the reds and after a reset i had sound but blank screen.

thanks in advance

               I had the E74 1022 problem and fixed it with the x-clamp and heat gun trick.  But now I have created a new problem and a rather annoying one.  Now the xbox bots up fine and no video problems but now the audio is out of whack.  basically I am getting a buzzing noise kinda like the buzzing sound of an out of frequency radio station.  The buzzing is only affected by bright colors.  The brighter the colors on the screen the louder the noise gets.  Just an example when playing COD4, if a flashbang blows up in my face the sound is very loud and in contrast if the screen is black you can barely hear it.

Now I havent ruled out using a different A/V cable beacuse I havent had a chance to get another one to try.  The first fix I used omn my system was the x-clamp and It would only work for about a week or a few days at a time.  After reading this thread I used the heat gun and it wasn't til after I used this method that I started having the audio problems.

I am wondering what component I may have heated too much and if anyone else has had this kind of problem

Thanks

Hmm thats quite weird looks like anything still wrong.
Must be the scaler chip though as I dont see what else would cause anything depending on the brightness...

My question is when you take the heat sink off and are about to attempt the reflow on the bottom of the mobo, where is the mobo sitting? are you just sitting it between 2 chairs? is it propped up or is it lying flat on the table? Im just asking because if you heat the chips, would you not want pressure on the chip so it can be reseated or is it just a case of just melting the solder a bit?

I tried this and it worked for about a week (presumably it failed because i didn't do it for long enough the first time), did it again and now my xbox keeps giving me overheating errors (2 red lights) after 4/5 minutes of being on. I tried replacing the thermal paste again to see if that would help (in case the heat gunning damaged it), but to no avail.

Does anyone have any suggestions as to what I could try to fix it?

Hey lads,

Looking forward to trying this out tomorrow..

My only question is; I havent received an E74 error yet but im sure its coming! I had 3 red rings a few months ago and used the x-clamp fix and its been great until a couple of days ago. Now, after a while of playing i start getting blue and yellow colours coming all over the screen. Ive included a couple of screenshots to show you what im on about..

IPB Image (http://img710.imageshack.us/i/24122009043.jpg/)

When this first happened my mate who i was playing with told me to switch the xbox off and on again, i did this but when rebooted i just got a black screen.. i could still hear sound through my turtlebeach headset but none through the TV. I ripped the xbox apart and applied new thermal paste to both heatsinks and whipped it all back together.. it worked!! huh.gif I was over the moon but then, after a while of playing again.. i got the same problem! It seems to only happen when the xbox has heated up a little, it can sometimes go after i play through it but it always comes back within a minute or 2. Switch it off and back on after the problem and get the blank screen, if i leave it a while it boots up fine and soon after that im hit with the same problem again.

Now im just wondering if its worth me trying to use this fix or is this a different problem??

Sorry for the long post but i wanted to make sure i gave you all the info

Thanks in advance for your help  biggrin.gif

Hello All,
Just fell upon this forum because of this thread and this is a cool place.

One of my friends had his Halo Elite Xbox with the E74 (H)ANA chip problem,
so we did the heat gun and a hybrid x-clamp fix with a heat gun that did 600 F and 1000F
My friend is a very neat person so we covered everything with foil, and did 1 min on low power and 3 min on high power.  We did both sides with 40 minutes break in between each time.  Worked like a charm after that, I will report any other findings as soon as they come up, keeping fingers crossed.

Just as a general consensus how effective is this method, and for how long?
I am pretty sure the answer is not  100% effective and permanent but a high number would make me happy.

Thanks for the tutorial with detailed pictures! I used the same 'el cheapo' heat gun as the OP, set mode to Low (up to 750 degrees), only heat gunned the highlighted area on the bottom of the mobo. Heated it for about 2-3 mins, then cooled down for 10 minutes.

Booted and is playing games fine!

Thanks jimwross, i finally got my 360 going only after doing your method.

i previously heated chips before assembling heat sink, (the same way i tend to fix the dreaded RROD, tried 3 times, xbox would boot up then the screen goes fuzzy within a couple of mins.... i was almost ready to bin it, so i gave your method one last crack put cleaned chip & heat sink,,, repasted,,, screwed back to motherbord,,, whacked my heat gun on area as you pointed out,,, let it cool down...

Then blow me down with cotton socks,,, back online playing CODMW2 for last 7 hours,,, & its still running sweet...

I told my brother how to do this over the phone to fix his xbox.

It already had the xclamp mod that I did to it... So took off the heatsink of the gpu and tin foiled around everything except the blue area in jimwross' picture below:

IPB Image

He had an old heat gun that only had low or high setting so I told him use low.

He heated in circular motions around the blue but focused most of the time on the red square, all for a total of 3 mins.  Hooked it back up after an hour and it works!  Did not need to heat the top.

Thanks everyone I think this is the best fix for E74 errors!!!  Hairdryer on ana chip is only temp fix

If I did it I would have taken pictures but I only told how to do it over the phone so I don't have any, sorry.  sad.gif


I just did this to my launch 360 (oct 2005 build) and it worked! I was getting E74 error, I tried xclamp fix,pennies, towel trick, regreased gpu / cpu and still no luck, So finally I tried doing exactly as described in this post (only did bottom, removed gpu heatsink,cleaned off gpu grease before using heat gun). I also put foil around the blue outline areas just in case.

Not sure if this is a longterm fix but still must say Thanks for the info  smile.gif

Am hoping someone can help me make sense of this...

Initially, had E74 with 2 or 3 red lights (forgot by now)- did the xclamp fix.
When I hooked back up to test, I had just 1 red light E74.

Does this mean I didn't achieve correct even pressure with the bolts and washers (over tightened perhaps- the board seems a little warped when placed back in steel cage I/O's not lined up really well)
BTW just how tight should those bolts be torqued down???

I tried the heat gun method after got the 1 red E74 but nothing- have repeated a few times- perhaps not getting quite hot enough?

thanks for any help in advance,
Jason

99% of the time any problem that comes up with the xbox 360 (expect for drive issues) is GPU.  

Get your system fixed right by getting it reballed.  Reball is where you lift off the chip off the board clean the old solder, place new lead based solder, then resolder the chip back on.  Not sure how to do this?

We do it.

Quick update, This fix lasted 9 months before RROD (E74 again) so I'd say the heatgun trick is fairly effective, It ran flawless for those 9 months no crashes / freezes,  I used a heatgun again and it's back up and running.

I noticed when I took it apart the gpu heatsink bolts were a little loose so that may of been part of the issue this time around, but I used heatgun just in case.

2005 launch day unit still in action lol.

I had two Halo 3 Xbox's Getting E74 right after a RROD fix. SO, got my $9 Harbor Freight Heat Gun on low, and a couple minutes on the bottom side of mobo to hana chipwith foil covering everything and re applying artic silver xbox plays fine. Both were little slaves during some GTA 4 cutscenes and high speed drives to work the GPU. Each going strong after 3 hours of gameplay.

Ok, so I've followed the guidance in this thread because I originally had an E74 error with one red light.  After adding the x-clamp fix and heating the designated region with a heat gun on both sides of the board, I let my xbox cool down and am now getting two flashing red lights on the left side along with no video at all.

I've also ensured that I only added only enough arctic silver to cover the tops of the chips with a thin layer prior to reinstalling the heat sinks...

Will going through this whole process again fix this issue? Help!!!

This did work for me on three different Xbox 360's. One thing that was not mentioned was how long to do it for. I used the heat gun on high for 2.5 minutes and then let the 360 cool back down for several hours. After this I put it back together enough to run and gave it a shot.

One 360 was fixed after the first try with the heat gun, another took 5 times. Eventually all 3 went back to E74 after 1 - 6 hours of gaming on them so I repeated the steps and got them working again. Re-testing all 3 now by playing games on them to see if they stay fixed.

One thing I will add is DO NOT do the other method some have suggested of unplugging the fans and letting the unit overheat to try to fix the E74. You will only further damage the console.

I found a Falcon at a yard sale for $50 with several controllers and several guitars and the RB drum set.  Of course, when I got it home it had the E74 error.  I followed your tutorial and it seems to be working quite well now (several nights of playing).

However, I am having one strange issue.

After putting everything back together, I notice that the ring of lights on the console doesn't work at all.  There is also no light in the center showing that the console is on.
On top of that, I can't sync any controllers wirelessly to the xbox.  If I sync them on the play and charge cable then disconnect the cable, they work fine on wireless.

I wouldn't mind too much, except that I can't sync any of the wireless guitars or the drumset.  I've tried holding the sync button on the console, every order I can think of (controller/console/both) and nothing seems to work.

I even ordered a replacement ROL card (the card with the lights that plugs into the front of the console) and it has the same problem.

Any ideas of what I should try?

Thanks for the awesome E74 fix!!

I wouldn't suggest this but I figured what the heck.  Stripped everything down cleaned chips under heat sink.  I didn't have a heat gun or hairdryer so I used a hot butter knife that I bent the tip on.  Just heated the knife on the stove and when it got hot placed it on chip and think I could actually hear it re-flow the solder.  Plugged board back in and the thing booted up no more E74 smile.gif

Have  one I fixed for a little bit with the xclamp fix and I might try this to see if I can bring it back to life.  its way more dead though worth a try.

Wish I could have my Error420 nick sad.gif

I must have figured something out >:)  Just tried my Hot Butter Knife trick on one that basically had no signs of life other than 3 red lights of death and nothing at all would show up on the screen not even a error message.  The second one I tried this on had the xclamp replacement already done and that only lasted a few months before it died hard. Its been dead and in the attic for years, which is great because it hasn't been updated for years.  Think I might try to get some homebrew going by JTAGing it.  Just thought I would share what I found.  Others have probably already done this and just haven't read about it.

Thank God for backups.  Still have my backup from 2006 of my 360's Sammy DVD smile.gif  Gunna let this sucker run for awhile and see how it doe's.  Gunna have to pull my Sammy outta another box that has a totally different issue and get the firmware for this box back on it, the thing still has blades smile.gif

e74 is a bad gpu, i supply thousands of GPUs online as well as use them in my shop and we sometimes get e74 on them which is fixed by putting a new gpu on it

in the past i did flows on them and they worked for a while but e74 is an issue with the chip not the board

for example if you take a e74 gpu and put it on another console it will give it e74

I am starting to think this too. Reball or reflow, a few days later/weeks later, E74.
