The picture is snowy, reddish tint to snow, almost a negative image sometimes.
If the menu and OSD are OK, that probably eliminates the panel and TCON board. That still leaves the A3U board which does all the switching and intial processing of the video signal and the B board which does final video process and panel drive. The is one simple way of narrowing it down: hook up a PC to the 15 pin VGA connector (make sure the PC is set for a 60 hertz refresh rate). If you can see the problem when using the computer input, it is most likely the B board. The B board is the most likely cause of video distortion problems. Please be sure to rate this solution. Thanks!

All inputs are effected. The menu and Display look pretty normal.
I assume this 15 pin VGA connector is inside the box?
Found it! Thanks!
I had to borrow a VGA cable and I tried hooking a PC up to the TV. The picture is bad that way, also. So I guess I need to replace the B board to fix this problem? Is it obvious which board is the B board? Where can I purchase the part?
Thanks for all the great help!
Does this happen on all inputs? Does it effect the On screen display and menu as well?
picture is bad
