    Hi all.

    I have two of these beasties, both JVC 42" plasmas made at about the
    same time.

    Unfortunately, one has a burned out PDP (has big black line on the
    screen about 1/3 the way across and halfway down the screen) and the
    other has an apparently fried controller board but the PDP looks fine.

    I've got as far as determining that the base boards are not
    mechanically compatible but they do use the same PDP, with essentially
    the same pinout and specifications.

    I can't seem to work out how to separate the PDP and uber-fragile
    flexi cables with embedded LSI HV chips from the base plate with its
    incorrect screw locations, undid about 24 screws and no go :(

    Has anyone even attempted such a mammoth task? It seems feasible (the
    LCD I modded is easy by comparison)

    Thanks in advance.

    Conundrum..

    Ouch! GOOD LUCK!

    And just think, folks make fun, now days, of people with CRT based
    sets. At least you've got a chance repairing them relative to what
    you're contemplating going through!

    I'll believe I'll stick to my free 25" stereo (CRT) TV set that was
    given to me with a vertical oscillator/amplifier & a few electrolytics
    that needed replacing.. While it certainly won't look as impressive as
    a new plasma based set, it's certainly not as expensive and sure
    significantly less work and cheaper to repair. In addition, probably
    doesn't cause quite as much RFI as most plasma sets tend to do!

    Cheers,
    Mr. Mentor

    Plasma and LCD sets only look impressive to your neighbours who haven't got
    one, or if you see them in shops running on a Blu Ray HD DVD player.
    Otherwise, compared to a good (or even mediocre) CRT set, the picture they
    produce, is crap ...

    Done, and fixed. The panels are held on with lots and LOTS of thermal
    strip, separating the panel is time consuming and nerve wracking but
    possible (be careful of the pip though, $$$$$$$$. The replaced panel
    worked fine once I had replaced the blown bus IC's on the XY scaler
    boards (caused by the original bad panel blowing a driver chip) so its
    worth checking these (they are the first things to blow when a driver
    chip craters itself)
