Plasma tv help?

If I had to take a stab in the wind I would say that your DG board is going south... Open her up and check the cable that runs from the DG board to the D-board and make sure its tight. DG board failures fairly common on the Pana's

please keep in mind that I am no tv repairman as you read my response...

I pulled the back cover to do as you said. I have been crossing the numbers on the boards to determine what they are (by searching the internet). Of all of the bigger boards, nothing comes back as a DG board. I have a power supply board, ss board, j board, d board, and a sc board. Also, several smaller boards that I did not research yet. This tv was formerly used as a lobby monitor at a tv station (just showed their logo all the time). Could this be some different (commercial?) type of tv? Any more suggestions or ideas?

thanks,
John

The DG board is the main board, that has all the video inputs attached to it, all the other boards attach to this board. May also be the AV board.
