Need help with Toshiba 32AV502R TV. No picture or sound, just lines

[shaundh]

I'm having a hard time getting started trouble shooting this TV. When I got it, it would turn on (I get green light and backlight) but I got no picture or any sound. I just got some vertical greenish lines on the left side of the screen. I took the panel apart and touched the flex cables connected and there was no change. I switched inputs and no change or sound. So I guessed it was the main board. So I found a mainboard on ebay, installed it, and the exact same behavior as before. I was sure it was the main board because I got NO respose from volume, input, menu, nothing. But it's still doing the same thing. I have a meter and I'm going to test the voltages now, but I'm pretty stumped. Any advise on where to start?

This is what it looks like.

Update: I finally got sound from the TV. I kept switching through the inputs and turning up the volume until I got a noise from the Apple TV menu. I can hear clearly but there is no movement on the screen. There are greenish white vertical lines across the whole screen now. I'm guessing that the panel is bad. It's just strange that I can't seem to agitate the problem by touching the flex cables. So, am I right in assuming the panel is bad?

Bad panel.
