first i had no video with audio, then i used the hybrid xclamp fix. this got it working for a couple of days but eventually got the e74 error. so i used a heat gun on the hana and gpu, it fixed it for 2 weeks but stress testing showed it was not a true fix. so i heat gunned it even longer this time, its a 850f gun so i was kinda scared the first time and might have not reflowed the chips all the way. but now its working again so i hope it stays like this, i will stress test it for a month then call it fixed. good luck to all trying to fix there 360s.

I have a halo ed. box with the 2nd gen heatsinks and an HDMI out, it has the e74 problem. I have redone both heatsinks to remove the clamps and apply better thermal paste, i was hoping that would fix it. I havent seen anyone mention a newer board with these problems, will the heatgun method work, or more importantly is there any reason i shouldnt try it. Thanks for any advice

It should work fine. If you heatgun anywhere else on the board, be sure to take off the heatsinks. Just be careful and follow the directions.

My E74 error fix was this........... I X-Clamped the CPU only. I did not do the x-clamp to the GPU. I did the Arctic Silver on the GPU and did the same with the X-Clamp on the CPU. Works great for the moment. I have let it run non stop for 2 hours and counting. I am going to let it sit for a while longer turn off then start it back up again to see what is up. I will post my results later.

Thanks to all for this.....

My 360 was giving me all sorts of trouble....the main one was the one red light, followed by 3 rings every now and then....but the main light was always e74 one red....

I went about the x-clamp...this was very temperamental after this fix...it would work for awhile....id turn it on, play for awhile...then it would start having artifacts on the screen....id keep adjusting pressure on heatsinks and it would work for a little....then start to e74 on me!!!..

Then i came accross this fix....it worked 1st time

I didnt have a powerful heatgun...only one that went to 500c....this was more than enought though..

I heated the back of the board focusing on the gpu and ana side in up and down motions...keeping the heatgun quite close to the board....i done this for about a couple of minutes...back off for a bit and then reapplied....i heated it up to a stage where i oculd see a bit of fumes coming off...though that must be enough and stopped it.....waited about 30mins and made sure the traces were cold to touch.

Reapplied my heatsinks...tested and worked first go!!!...i had the 360 running all night just to make sure it doesnt have any weird artifacts and doesnt ring on me again...all fine...i turned off in the morning and back on, all perfect

....how do most on these boards test to make sure any fix is working properly...leave it on full all day long???

THANKS FOR REVIVING MY XBOX 360:)

On a side note: Can you really do much damage to the board heatgunning from the backside of it?....i mean all the danger stuff is on the top side like the big capacitors etc???....im really happy to fix my 360 though really need to know when to stop heatgunning...what do most go by ... im guessing too hot is no good...but no enough will make the ring come back eventually....

Please help - Did i fry my motherboard?

Hey guys, i tried to fix my E74 fix today.....i concentrated the heatgun on the gpu and ana chipsets, only for 1min on high but close to the motherboard...always moving the heatgun....this was only for the underside of the board as in this tutorial...i thought since the underside has no big capacitors etc it would be ok...

Anyway, i saw some smoke coming out so i though this would be a good place to stop...i then hear what seem to be a crackling noise???.....what would this be?....

What was an e74 to begin with....now is either a 2 red lights, or 3 red light error....

It takes a long time to display the rol now...the middle green light blink for ~10-20secs, then displas the RROD or 2lights.

Please advise what i done wrong?....my heatgun gets to 500c and it seems it fried my board...why the the console still go though>?

Also....how do i know when to stop heatgunning?....this is a big one for me...i fixed my last 360 heatgunning with no problems!

nsta · « **Reply #337 on:** April 16, 2009, 04:28:00 PM »

Could someone please reply to my email above, and advise if should just sell my 360 for parts now?....the crackling sound makes me think i blew the board....

Is there a video showing how to heatgun the board properly?....ie from behind in this message....i went from a 1 ring e74 to a 2 ring, then a 3rrod so im sure its dead!...

FYI the part of the board underside i heatgun looks verygold bronze, im guessing i fried something by heatgunning too close...is there a distance away to heatgun...i need to know when to stop!

I always thought that since we are heatgun the backside of the board that nothing would happen, though it seems something crackled and maybe popped for me?

Hi,

i tryed the method of reflow, but still get e74, but is strange..if i open all, and leave only the board and make a little overheating, like 15 mins, the e74 goes away. But this is not definitive, because is back again. Is like whne the gpu is hot, the stuff back to work..Any tip? the i reflowed no the back side of the board, the front of the board, is necesary reflow the back? with the xclamp put in on? thx!!!

I Will probably blasted for what im about to say.....but 95% of all my rrod adn E74 fixes have been repaired by only heatgunning the backside of the board, along with wilheims xclamp mod....the old one....this seems to be a proper fix that lasts and doesnt come back!!!

Do the back of the board focusing on the GPU and ANA chip ponly going up and down....ALWAYS MOVE THE HEATGUN....as it doesnt take long to fry something having the gun pointing at one area for long!...ive burnt a board like this before.

enito · « **Reply #340 on:** April 20, 2009, 10:08:00 AM »

Right, but is not dangerous apply heatgun with the xclamped put in on? like i see in the tutorial pictures?

i mean hot, with xclamp and plust the thermal paste, can be little dangerous?

thx

Yes it is not a good idea to heatgun the board with the x clamps on. Terrible idea actually, because if you actually DID achieve reflow then the force of the xclamps would probably squish the solder balls together and/or actually MOVE the whole GPU chip.. thats IF you achieved reflow.

Hey sorry please refer to the front page of the thread, do exactly as they have.,.....though PLEASE REMOVE XCLAMPS, REMOVE THE CPU/GPU HEATSINK AND ALL THERMAL PASTE..... then what i do is the wilhheim xclamp fix and ive nearly never had a problem right from the get go....95% success rate so far out of 57 machines!

enito · « **Reply #343 on:** April 21, 2009, 01:35:00 AM »

thx i do it today, and worked!!! thx for all replys!

Done this on 2 machines now along with the xclamp.

using m5 x 10mm machines screws from screwfix (UK) (Offer on at moment 1000 screws £4.92)
using m5 washers x 2 (none on base of board)
Thermal compound

And a 150c setting 1 to 560c setting 2 heat gun

stripped and cleaned, then heatgunned bottom of the board (1 of the boards flexed a bit like it was straihgtening out which freaked me out) 1min on low setting then approx 2 mins on high about an inch or so from the board using circular motions.

Then applied the new screws/washers/thermal compound and tightened. Both machines booted up first time with no problems.

One was a 3rrod no picture thed other was 1 rrod and E74

Time will tell how long the fixes last, if they come back a bit more time on the bottom of the board and as a last resort will do the top of the board but hoping to avoid.
