    Toshiba Plasma 42HP66 flickering and flashing

    Hi, I have a 42" plasma with video problems. It has sound, it turns on and off and responds to the remote and to input buttons on the set. The picture is very bad; it flashes and flickers and is distorted. I have the back off, as I hoped to find obviously bad components, but I do not see any. Suggestions, please?

      Looks like a bad Z-sustain board to me.
      Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

                  I thought I could easily find directions for testing the board, but I have not had any luck. Could someone point me in the correct direction? Also, will it hurt anything to disconnect the board and turn the TV on?
