How do I fix e74 error?
I have the74 error and I'm not sure how to fix this.
Bu iyi bir soru mu?
Having just repaired this on my friends Xbox 360, I followed the guide for RROD repair (as it had that first and then had e74). I found a picture of the HANA chip on Google with a hint to apply pressure on it when the Xbox is warming up. It took no time at all, and presto—we have working machine! I don't know how long it will stay working, but for now, it's fine.
The problem with e-74 is very similar to the RROD. Instead of the solder joints being messed up in the GPU or CPU, it's the solder joints on the HANA chip—the small black chip behind the GPU (closer to the fans). To fix this you can try to reflow the solder by heating the chip up to roughly 217 C for 20-30 seconds (best done with a thermocouple type thermometer to monitor the actual temp of the board) then letting the board sit for 30 minutes to completely cool down. When you reassemble the Xbox, apply fresh thermal paste to the GPU and CPU. I would not worry about doing the X-clamp fix, since your problem is not with the GPU or the CPU. I hope this helps.
I would just like to highlight three useful information about fixing Xbox 360.
#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.

Why wouldn't a few seconds of a heat gun on a medium setting at each set of chip pin's be enough to re-flow the solder? Solder melts fairly quickly under a heat gun.
I recently fixed a problem with a video card in my 2007 Mac Pro by setting my oven to 400 degrees and letting the card sit in the oven for like 6 or 7 minutes. Worked like a charm!
Stick to unfolded paper clips in the fans of the 360 to stop the air flow it may seem like you will mess up your console but in reality you will reflow the solder and fix it! When you boot up your xbox with the paper clips in it you will wait about ten minutes or until the single red ring turns into to red rings. Once that has happened you have to unplug everything wait like two minutes, while your over heating it ,if your watching it, the graphics may get scrambled don't worry that is perfectly normal ( it is a sign of progress actually). After it overheats unplug everything from the back including the av cable, the power cable, and the paper clips. ( don't even bother to hit the power button before unplugging it). After that you will wait the two minutes and plug in everything again (excluding paper clips) and power it up you will notice that it works now.
