    LG 32PC51 ( Plasma burn in and sparkles )

    Hey guys!

    So i got this plasma wich turns on perfectly but is having issues with the screen.
    On some input channels i get the "burning in" problem , so without anything connected to the tv and input is HDMI i see the comedy central logo but its gone when i use the menu or use TV input. ( snow )

    Also when i use the factory settings and reinstall the tv its completelt gone but the Menu itself will burn in inmediately. So after installing the tv with the correct language/country etc and i select HDMI 1 i see the menu in the background...like a burn in.
    Is the dynamics to high or is this something else? I almost want to degauss the tv if that was possible haha.....
    Is the screen getting to much power? I also get red sparkles in the lower left corner after 5 minutes , also around the lines of the menu i see also sparkles..

      Looks like image retention to me. Worth checking all panel voltages. May need LG firmware update flashed to fix.
      Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
      For service manual, schematic, boardview (board view), datasheet, cad - use our search.

        Thx for the reply! Checked the voltages and they were 5v to low , replaced some suspicious caps on the ps and altered the voltages to 195v

        Sparkles are almost gone , some 5/6 random sparkles!
        Anyways just looking for 1 minute at the menu and i get this...
        Can i fix this by myself?

            Seems like part of your picture is missing too. These 32" plasmas are pretty unique as the X,Y and Ydrive buffer are all on one board.
