Right i had some guy bring round a broken 360 for me to fix no mention of what was wrong with it when he brought it round i found it had a E74 Error.
Which is the Hana/Ana Chip problem
So heres my solution this is a complete DIY fix so this is no permanant fix but ive found it to work very well the reason i tried this is microsoft didnt cover his console for warranty anymore.
So only try this is as a last resort try your best to get MS to fix it for Free
Things You'll Need:
1 x E74 Error'd Xbox 360
1 x Roll Of Electrical Tape
15 x Pennies
1 x Hairdryer
Step 1: Take the console apart taking off both sides of the case removing the dvd drive and white funnel for airflow.
Step 2: Locate the Hana/Ana Chip (it's too the right of your A/V connection)
Step 3: Get yourself some electrical tape and get 15 pennies and tape them up in this order
3 sets in 4's and 1 set in 3's
then tape them together as one so you should end up with a big stack
Step 4: Get yourself a hairdryer (not a heatgun as it generates way too much heat i found a hairdryer worked very well) now plug your Hairdryer in put it on the hottest heat setting and get it as close as possible to the Hana/Ana Chip leave it there heating up for a good few minutes you'll notice the outer casing get very hot when finished
Step 5: Plug the 360 back in still hot and see if she boots, if so goto Step 6 if not repeat Step 4
Step 6: Get the stack of pennies you made earlier and place them on top of the Hana/Ana Chip and tape it down with some electrical tape in the shape of a plus sign ( + ) then put the white funnel back on and apply pressure to make sure it fits snug tape it down with some more tape next put your dvd drive back in place you'll notice the back end will be slightly elevated
Step 7: Put the top part of the case back on leaving all the bigger torx screws out which you removed earlier (why leave them out you ask? i found if i put them back in after i tightened them i got a RROD Error 20)
Step 8: Put all remaing case back together and reconnect all your cables and test again and we should see the console boot.
This may not work for everyone!
This is taken from the idea of the penny fix by another member of this forum it still has the general idea of colder solder points which need reinforcing.

Should i leave the motherboard in the metal casing when doing this ??
should the hairdryer face the top part of the board or the botto part??
and just some contridtion
if u press down on tha hanan chip can't u bridge the BGA if its a bit get metleted

also answering questions i left the motherboard in the metal casing
i applied the hairdryer for at most 2 to 3 minutes so while i was putting the console back together it remained hot so it didnt e74 again before i got the pennies to apply the pressure
also the console i done this on has been playing fine all night with PGR4 GoW and Halo 3 also has been left at the dashboard for 2 hours for testing

1 set of pennies each set contains 3 pennies

ive got 2 e74 error consoles here, I've done the x-clamp to both and that fixed it for a day or two but just artifacts on me then gets the e74 on reset. i can get them to boot and play for about a day by tightening/loosening the screws. i haven't found anything permanent yet

it doesn't matter whether this is a temporary fix or not, all that matters is IT WORKS!!

If there is a problem in soldering on pins then we can resolder that pins. I think by resoldering, we will get better results.
BTW, resoldering ANA chip isn't something that everyone can do but a person with medium soldering skills can do it by spending an hour.
I've done it before without any problem.
Good luck

ANA chip isn't a BGA chip so I don't get the reason of putting pressure!
im guessing that it pushes the pins down onto the board a bit more and heating it up makes it cling to the board (not solder it to the board cause it doesnt get that hot, but just makes it stick a little bit)
but the E74 error is not always a broken connection on the ANA/HANA chip though, it may be the GPU, or anywhere in between the GPU and the AV port, it could be that something is damaged (ie, a bus or the ana chip) which is either corrupting or stopping the data all together

and do any of you experienced turbo-charged fan? this is when i applied this trick, i also put in the black screw driver but not so tight, just as long as it holds the board firmly

i gotta try this on a 360 i have with this error
i'll post the results here
thanks again

i think i'm trying the 2 penny trick after it cools down
Post by: shah87 on October 29, 2007, 02:06:00 AM
i restart the console, later after that the problem is starting again
then i decided to open the console and remove the pennies that were stacked above the ANA chip
after that, it works, no more graphical glitch after 3 hours of gaming, hope that it stays like that

Can I reflow the ana chip and it be cool?
In order to fix it permanently you will have to reflow the GPU and do the X-CLamp fix afterwards the cold joint that is causing this is in the upper part near the ERAM die...
The ANA-chip is not BGA it has got pins and the chance that the problem is the actual ANA chip is very very low...

The really issue is not the heat, please guys! these chips can run well in these temperatures. When the Xbox was designed the soldering used was of such that is solder melt point was well over 200deg C so unless your running at 200C or more your problem is the not really heat!
But then again, heat causes expansion and contraction at high and lower temp, and this is were the system fails. It causes micro fractures under the chip ( mostly if not always the GPU ) screwing it tight is a fix if the fracture is really small, but since its there is WILL grow bigger!!!!!!
if you reflow the chip correctly, you did fix the problem, but not the reason for the problem, its still there and no X clamp upgrade will remove the reason for failure. NOTE!! overheating you xbox with a towl is not a reflow! heat-gunning it is also not a correct reflow but ,might work the solder melts at 217.C anything under that is a total waste of time and effort.
I have seen Xenon's running 24/7 at 90.C and are still working, since there is no expanding and contracting of components, there is no real reason for failure.
so without removing the reason for failure, no fix you do on your X-Box will ever really be fix your X Box

I wish the moderators would delete all these stupid "overheat and crush" tricks! Reflow or Reball are the only real fixes. Cooling mods are the only real prevention. Aside from also making sure MS didn't flex the board on installation.
