    Samsung Plasma PN51D450A2DX display problem

    Hi everyone, this is my first post so go easy on me. I have a chance to buy this plasma 51 in 3D plasma for $150 with a display problem, see the attached picture, that's the only picture I have right now. Anyway the owner said the TV shop told him it was a bad Disply Panel. I'm not convinced of that, could it be a bad lower buffer or logic board? I need help in deciding to buy it or not. All the boards for this set are fairly cheap on ebay.
    Thanks for any help on this.

      If you're talking about the lines on the screen - I can't quite tell - then yes, it is a bad display panel and is unrepairable (without replacing the plasma panel, which costs a lot of $$$.) It is caused by the chips embedded on the FFCs for the plasma panel going bad. In this case, it looks like some kind of sustained EOS (electrical overstress) has damaged a lot of these chips. I *could* be wrong - there is the rare chance it's a control board issue, but I doubt it.
      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.

          Thanks Tom66,
          Yes, I did mean the white area and those vert lines on the bottom. So, it sounds like you're pretty sure it's not a buffer issue and most likely a bad display. I guess I'll pass on buying this one, too much money anyway. Many thanks for your fast reply and good advice. I have repaired many LCD TVs but fairly new at Plasma. Thanks again.

              Samsung QN75Q70TAF - Problem ON or WITHIN the Display??
              by KYBOSH
              Came across a 75" QLED TV with restart-backlight no boot and it was headed to the dumpster. Asked the owner to let me have a crack at it. They said the TV went out during or soon after a thunderstorm. I noted this but didnt out too much stock into it as it could have been anything.

              VERY big TV and i was worried about the display cracking during the moved as well as the repair but it was alright as i try very hard to handle with care.

              In the video (zip file) you can see' as the TV tries to start up, tbere are a lot of gaps in the backlight so I immediately suspect...

              un60j620dafxza - Samsung No Display Problem
              by stylishconsultant
              Hi All,

              Need help.

              I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.

              So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
              problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
              might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard....

              Problem with LG Plasma 60PM6700 - Random power downs
              by theone111
              I have an LG Plasma TV 60PM6700 for the past ~12 years.

              In the last ~3-4 months I have been having some issues.
              1. Problem: It started with random picture disappearing (sound still worked).
                Frequency: Happened about once a week.
                Solution: Had to turn off TV wait a few seconds before turning it on again.
              2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
                Frequency: Happened about once a week.
                Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
              3. Problem: TV shuts down
              ...

              Display problem on a Samsung U28E590D
              by Neptune06
              Hello,

              I have a display problem (bad size and color) on a Samsung U28E590D and i'm wondering if someone have access to the service manual for this monitor. I used a faulty Lenovo thunderbolt hub connected to it and now i suspect a problem on the HDMI part of this monitor. The main PCB board part number is: BN94-10748G.

              Thanks for your help.
