I replaced the Hard Drive. Went through the TIVO guided setup. I had audio and video and all seemed to be working fine. Now I have no video, although the audio is working. What could have happened? I have checked to see if my VCR is working and that also gives me audio, but no video. I also have hooked the cable directly into the TV and get only audio, no video.

With some reluctance, I hooked up another television, and I have both audio and video. Obviously the other television is bad.

The real question is whether I could have really messed something up with my TV? The TV was about 8 years old so i'm not that worried about it, but I don't want to go get a new tv and damage it.

Was it really just coincidental?
