    Similar problem, we have red lines thoughout picture, tried replacing main logic board, no avail. Looking at PSU and X/Y sustain boards. Any help would be great. Is claimed that the majority of probs w/ plasmas are power supply related.. any hints on checking this with a voltmeter?

After you remove the back cover inspect the power supply board for swollen or bulging capacitors. Pull and check any capacitors that you suspect to be swollen. Next, look for a sticker in the upper right hand side of the TV set. Use the values you find on the sticker to calibrate the voltages on the power supply board.

I think you have a frame fault on the tv. If you are capable check the picture frame board first. If not find a competant technician. Good luck.

I think its something on the picture frame board or on the line output board. I would sway to the line output simply because I think but not sure that error code is linked to the line output stage plus when you unplugged the cable the voltage seems within parameters. Good luck.
