    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.

                Panasonic P42S30 Plasma - Pink sparkles
                by Lintesir
                My parents' Panasonic P42S30 died recently, and they asked me to have a look at it. I was able to identify the SN-board as the culprit, as it was shorted. After removing Q401, Q402, Q421 and Q422 the short was gone, so I replaced these components and that got the TV working again. However, when testing the tv a bit, I noticed quite bad pinkish sparkles on some colors. For instance the greyish bar on this forum seems to trigger it quite badly. I made a fullscreen test picture with only that color, with the below result.

                There is about a 5cm high region at the top without any sparkles,...

                HANNSG Hi221 -- 2 secs to black feat. CCFL flicker & "burn" marks on power board
                by ttmi100x
                Greetings everyone,


                I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...


                The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
                Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.

                Upon closer inspection...

                Insignia NS-43D420NA20 backlight on no display - LCD panel burn failure
                by howardc64
                Eventually discovered a burn mark near lower corner of LCD. Here is a summary
                • Backlight on, no image
                • Disconnect right buffer board (view from front), left side display comes on
                • Masked off pin 7+8 (both ~12,5v on both left and right buffer board) from t-con to right buffer board (view from front) display works but have some lines
                • Buffer board is pretty simple
                Removed the front bezel to examine edge of the glass. Found burn mark on lower right (view from front). Plastic bezel covering the burn mark region shows heat signature on the inside surface facing the LCD panel. Last 2 pics. Bright...

                by Retro140
                Hello,

                So I was referred here when I made this poste over on AVForums: https://www.avsforum.com/threads/loc...lg-tv.3257234/

                To summarize, this is a commercial TV and I can't get a menu of any kind. I know the overlay is working because when I change channel, adjust volume, turn on sleep timer I do see text. But I have not ever seen the user menu nor the installers menu. I've tried a bunch of remotes(more info on the AVF post) and tried every button...
