Xbox 360 E74 Repair Guide
Chris, ' E74: AV cable error. There is a problem with the AV cable, try using a different AV cable. If the cable is known to be working then there is a 90% chance it's a scaler chip problem (the 'ANA' or 'HANA' chip connected directly to the AV cable) in rare cases it is the GPU.' Check on for more info on that.
I've been looking everywhere on the web, stores, people everything, but i can not find anyone that knows how to fix E74, all I can find is to over heat your xbox. Got the Xbox 360 one red light error? This error is also known as the E74 error, and it's mostly caused due to overheating problems. So now you know this, you'll be. The Xbox 360 is the second video game console produced by Microsoft, and the successor to the Xbox. The Xbox 360 competes with Sony's PlayStation 3.
What you have is basically a variation of the RROD. In your case it is not the CPU/GPU that is giving the error, but the HANA chip. A reflow of this chip might resolve it for a while at least. A permanent fix would be to reball the chip.
Check for some idea on how to reflow and do stay away from purposely overheating your console. Hope this helps, good luck.

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 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. Good Luck, Cody. To get a good reflow its best to heat the bottom of the board which can done with something as simple as a griddle(look on youtube youll see what i mean) and after the top of the board gets to like 100ish degrees c apply heat to the hana chip with a heat gun or something similar till the board gets to 217ish degrees c this will melt the solder and reflow it. There are videos on youtube if you just search xbox 360 reflow or something like that. Hope this helps. Good Luck, Cody P.S. Get board temps with a thermocouple type thermometer.

How To Fix Xbox 360 E74 Error
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.
