Yesterday I followed the tutorials here on the site where I did a reflow and then used the ifixit RROD kit. Now I tried turning it on and it instantly gives 1 red light with the E74 error. I have tried removing all accessories and the HDD and unplugged and replugged the cables but it keeps showing that 1 light. It also instantly started to feel very warm. Is there anything you guys can recommend me? I don’t want to just randomly try things from google as I do not want to risk damaging it even more. Thanks in advance guys!
Tamara, tell us more about how you did do the reflow. 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 here for more info on that. 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 on herefor some idea on how to reflow and do stay away from purposely overheating your console. Hope this helps, good luck.
