  • Plasma Monitor Faulty "Video Driver"

    .

  • #2
    42" plasma screen
    Does it at least work with composite video? With R/G/B Cables? because normally drivers dun cause such problems......and it doesnt seem like its a controller problem...

    from what i hear....Once a plasma go bad....it goes bad!

      Well, it seems the plasma went bad.
      Meaning, what happeneds in plasma (unlike lcd) is that if an image is projected for some time its burnt in the screen.E.g: the logo of a chanel (CNN 4 example) will be burnt forever if you wont pass the channel every once in a while or if your plasma doesnt have protection software(on her bios) meaning. The new plasma have several utilities for protection:
      1. screen orbitier- a utility which will move all the pixels for 1 ms or so every once in a while (or it will blink the screen with white/black)
      2. DPMS - will reset the screen power fuse.
      note u can turn both OFF! , my guess is or the guys u bought it from didnt used such or their pixels got defected other way around.

            Your best bet is to :-

            a) Find where the drive lines for that section of the plasma are ( they may be all around the edge, I've not had one apart for years ).

            b) Patch a working sections lines to the bad area.

            c) If the area now lights up you know the display itself is fine and you can look at the drive cirsuits.

            d) If that doesn't work, bin it. You'll never fix it.

            With these things unless you're very lucky with your source of the display, the price will give you a clue to how likely a fix is. $3,000 display for $200...you work it out.

            Good Luck

            Cheers

              Don't worry too much, plasma also has a half-life of 3-5 years (meaning that it permanently loses half the brightness) so you only need wait 3 years and you'd need to buy a new one anyway. Plasma is a crappy technology at the moment; you get blurry pixels, quick burn-in, short half-life and it's expen$ive.
