    lg pa 650t pink ghosting

    can anyone help i get strange pinky coloured ghosting on my screen .seems to be getting worse ,its worse on white screens . the set is less than 3 years old and has been excellent . i found numerous threads with the same issue as mine and the fix for most seemed to be cracked coils on the x y boards . i checked mine and only found two coils that were ok . and i cant find any other dry joints .so im lost . im new to the forum and mechanically minded .but know very little about electronics . any help would be amazing x

        On your panel should be a sticker thats gives you the voltages VS/VA/VSC/VE see if your voltages match them

          Plasma Panel itself has aged.

          A temp cure is to increase the Vs while showing full-white screen--Till the fault JUST disappears, and NO MORE...

              Trust me it is the panel when they age they require more drive voltage to accommodate a brighter scene . I think it has to do with lack of The argon xenon gases inside the panel as a certain age they evaporate a little
              Did I leave the soldering iron on?
