Hi all, I previously posted in here about this TV, and thought I had the problem solved. I found some nasty cold solder joints and resoldered them, and lo and behold, I had picture. I had my cable box plugged in, so I decided to tune to it and see how the HD channels looked. When I hit the "TV-Video" button to switch to that input, the picture went away and never came back. I'm back to the old problem of no picture at all. I know the TV is working because I can hear the audio from the channel I've tuned to.
Any thoughts? Could this possibly be something in the circuitry related to tuning and inputs?
Thanks, Adam Dorsey
