Can anyone diagnose the cause of death of this Plasma?

    Hi All,

    I have a Mitsubishi XP-4015C, also known as a Leonardo 4:3 40" PDP, which has died a mysterious death. There's some kind of signal getting into it, but the display is now odd coloured lines. I'm attaching a picture in the hope someone knows what's failed.

    Question is, is this fixable, and if so, is it worth fixing?

    Pete

    I know nothing about plasmas but going by Leerock's suggestion that it is just a screen for calibrating purposes, is there a switch on the back that has been clicked or something on the remote to set the screen to this? I know on older videos etc they had switches to set a test screen, perhaps this has been turned on???

    actually the horizontal lines are what makes me think there is something wrong, gently grab the edges of the tv and squeeze the front and back together to make sure they havent come loose, do this around the whole screen, i've had lcd monitors do things like this before just because the case it was in was lose, clicking it back into place fixed it

    be careful not to squeeze to hard, im not taking responsibility if you break the glass and a shard flies of and hits your cat

    Well, I took the back off the thing; hoovered out several years worth of dust and put it back together again (making sure it was all seated properly as per your suggestion). The problem remains. I'm sure it's not a calibration thing, since the pattern of vertical lines are affected by whatever the input source is and there's also the horizontal corruption.

    Hi horny,

    The res is 640 x 480 (4:3), with the following inputs:

    1 x RGB via BNC connectors (R, G, B, VD, HD/CS)
    2 x RGB via VGA connectors (I assume 1 is a pass thru)
    2 x S-Video Inputs
    2 x Composite Inputs
    3 x Audio In Stereo Pairs
    1 x Serial Remote
    1 x Parallel Remote

    Yes. In fact the problem shows itself without anything connected. The pattern will change as the signal changes, so at start up the screen normally shows the current input on screen, and the produces one pattern. If I press the menu button on the side of the display, the pattern changes as I cycle through different options. When there's no OSD, the picture is black. Feeding a signal into it gives a pretty changing pattern of vertical stripes. At the moment it's expensive moving wallpaper...
