My dad and I fixed the TV/Video problem over the weekend using one of the solutions suggested. Make sure you stay away from the red wire running from the back of the tube to the circuit board.
1. Take the cover off the back of the TV.
2. On the bottom of the TV is a circuit board that is mounted on top of a plastic tray. Remove the cables running from the speakers by squeezing the tab on the white plug and pulling them up and off the board.
3. Looking at the back of the TV, pull the board+tray out (barely secured in there) and flip it 180 degrees so you're looking at the front of the board.
4. Desolder and remove the TV/Video push button. It's labeled on the PCB, and should be the second button in from the left.
5. Place the tray back in the TV and make sure the other buttons still remaining on the baord are aligned with the buttons on the front of the TV.
6. Put the cover back and you're done.
TV works as good as new again. Of course I can't use the TV/Video button on the TV itself, but the remote handles that fine. 20 minutes max, and no repairman needed.

Ok you have sound and no picture. This denotes that since this is a plasma TV the circuitry that controls the activation of the screen may have become defective. You will need the schematic to show the voltage levels that need to be present on the cable that connects between the screen and the control circuit and a voltmeter to measure those voltages. I would suggest that you get a qualified TV technician to work on this problem, due to the technical nature of this issue.
I hope this helps,

if you're using antenna, (most likely)you need to adjust your antenna to where it picks up the best signal. The picture comes in clear with good audio and doesn't pixelate often.

Try resetting the TV by leaving it unplugged for an hour.
Plug it back in and check to see if it works normally.
If that doesn't work, rule out the Directv box by pressing the reset button near the access card. The box could be putting out a signal that doesn't have video or audio.
If everything fails, have the tech man come back to check everything that he did before you use the warranty on the TV.

If you want HDMI 'Auto' mode (the factory default), you need a combination of selecting the proper output mode (use the remote's 'Progressive' button to toggle between the four output modes: HDMI, RCA VGA, component video out and s-video. Once you're in HDMI mode (the led's on the front of the box are a dead give-away!), then you can press the front panel 'HDMI Select' button to move through the five available HDMI settings: 480P, 720P, 1080i, 1080P and 'Auto'. You're in 'Auto' mode when all four led's are lit.
