#1 tip to avoid Xbox red ring of death is to prevent Xbox overheating.
#2 never try to re-solder Xbox your own unless you are knowledgeable at it or you have a repair guide with you.
#3 Don't wrap the damaged Xbox 360 console with a bath towel, it will not do good to your Xbox.

Source: http://www.e74online.com/ just sharing to also contribute helpful information to Xbox lovers like me. Thank you!

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

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

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.

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:

Heres the box with the problems

(IMG:http://www.mplsgaming.com/tutorials/360/e74/CIMG2750.jpg)
Case off, remove all of the screws, including the little black ones on the RF unit and for the x-clamps

(IMG:http://www.mplsgaming.com/tutorials/360/e74/CIMG2751.jpg)
Unplug the SATA and DVD power cables, unplug the fans

(IMG:http://www.mplsgaming.com/tutorials/360/e74/CIMG2753.jpg)
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.

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

(IMG:http://www.mplsgaming.com/tutorials/360/e74/CIMG2764.jpg)
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.

Clean the GPU off

Clean the heatsink off

(IMG:http://www.mplsgaming.com/tutorials/360/e74/CIMG2767.jpg)
Use the higher percentage rubbing alcohol

(IMG:http://www.mplsgaming.com/tutorials/360/e74/CIMG2768.jpg)
Apply artic silver, do the standard X-Clamp fix.

(IMG:http://www.mplsgaming.com/tutorials/360/e74/CIMG2769.jpg)
Now the parts we need exposed (underneath the stock x-clamp) are accessible.

(IMG:http://www.mplsgaming.com/tutorials/360/e74/CIMG2770.jpg)
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.


(IMG:http://www.mplsgaming.com/tutorials/360/e74/CIMG2771.jpg)
The motherboard is going to be HOT. Let it cool down.  Put the fans and the fan shroud back in, and test it out.

(IMG:http://www.mplsgaming.com/tutorials/360/e74/CIMG2772.jpg)
Woohoo!

(IMG:http://www.mplsgaming.com/tutorials/360/e74/CIMG2773.jpg)
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.

[brandogg]

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.

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

[brandogg]

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.

[jimwross]

Ok yeah, I guess it's always just worked for me so I haven't even thought about that!  (IMG:style_emoticons/default/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.

[[AD]]

How long do you heat the area up for?

[brandogg]

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.
