I was reading in a tut somewhere and it said to use FlashX to flash the Xbox Tsop. When I downloaded it, I noticed it was for designed for the modchip, but I figured it would work fine for the Xbox Tsop since the tut said to use it.
I did manage to find good news. Last night while I was messing with my problem xbox (no audio, no video). I had all the lights in the house off. I had my TV and Xbox on. I noticed the black screen on the TV had a rolling image. You couldn't make anything out, and was barely visible. The image was rolling from right to left very fast, then slows down to a stop, and begins to roll from left to right. Keeps repeating this pattern. Well one time while booting my Xbox, the pattern was slowing down to shift directions. When the image stopped for a few secs to change directions, I noticed my Big "X" Xbox logo you get when you first boot the xbox. You could barely see it, but it was there.
It doesn't really help me at this point, but at least I know the xbox is still trying to send out the video.
