    Samsung 50" Plasma PN50A450P1D vertical lines

    Looking for help in solving this vertical line issue. TV was off for 4 days and first power up shows a group of vertical lines (Multiple colors) going up the right side of the panel.

    From my quick reviews of the FAQ's and such it looks like it could be a simple repair but I am not sure. Before I take the TV down I would like to get a couple of possible solutions ready. I have access to DMM and other parts but am not that technical so any and all help is appreciated.

    Thank you,
    Rich

    Most probably is not repairable.

      It's either a panel issue (not at all uncommon for this Samsung model), poorly-seated connector on one of the address boards that run along the bottom of the panel in the vicinity of the defect, or a bad address board. It's hard to see the issue clearly in your pic because of the brightness, but I'd bank on a bad panel. My PN50A450 had vertical lines in a random pattern - bad panel.

        Thank you for your feedback. Here is a closer picture of the vertical lines. You can still see an image through the lines and the color pattern repeats.

        Does this help determine the potential problem?

        Thanks,

          A repeating pattern is a little more lucky, it may be just loose connector. It is likely to be a bad plasma panel though.

            Got the plasma down off the wall and took the back off. Checked and reset all ribbon cables and problem is still there. I notice that the main logic board feeds both E.F buffers with a 60 pin ribbon. Would I learn anything if I drove the E buffer with the signal meant for the F buffer?

            My fears is that the panel is gone but I don't have the knowledge to know when to "Pull the Plug".

            Thanks again,
            Rich

              Did you figure out what the problem was? I have the same problem.
