E74 Fix

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.
