First of all, this is not a go get a ps3 thread. i like xbox and i just wan't some help on how to possibly fix mine.
I have the e74 error. My xbox turns on normally without the AV cable but when I plug it in I get the error and rings. I have tried using other cables and it still does the same thing. I also did the q-tip trick and that made it work for about 15 minutes until getting the rings again. Any ways to fix it?
