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

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

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...

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

Followed this tonight and it worked a treat

Glad to hear it.  When I initially tried to find info on how to fix the e74, there was little to nothing to go off of.

Just to confirm one point.

You use the Heat Gun on the motherboard with the Heat Sinks ON???  or OFF???

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  

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..  


Thanx again.

Just clean the googone residue off w/ alcohol afterwards

[Boobers]

That's exactly what I do for the exact reason..

We must think alike..

I am sooo sorry for you.

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.
