    Samsung 37" plasma - bad colors inverted lines

    When I first turn it on the color is really washed out and the blacks are very light grey with lots of shadows and ghosting. After a minute the darks get darker but the color stays washed out light blue pinkish and ghostly inverted like.

    This is a Samsung LN37A550P3FXZA 37" plasma.

    Any ideas what board may be failing here?

      Thought it was a plasma but after opening I realize it's an LCD

          I would say AS15 chip fault. Post a picture of your tcon board. It can be tested.
          Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

              Samsung LS19A100, slowed down, colors changed, lines not very crisp
              by panoss
              In the above mentioned monitor, I removed the plug a few times and this resulted no power.
              I opened it, soldered the dc jack and worked again.
              But since then colors have changed, too bright (or something like this) and lines, eg letter, are not very crisp as they used to be, they are vague, like faded out.
              I checked voltages on the main board, they look ok (according to the service manual. It' attached at the bottom):
              IC600 (D9329)
              pin 1 (BST) 9.6V
              pin 2 (VIN) 13.5V
              pin 3 (SW(Switching output)) 4.8V
              pin 7 (EN)
              pin 8 (SS) 2.6V

              IC601...

              Verticle lines on Samsung PN42A400 Plasma TV
              by xNOTx
              Hello 👋 I have a tv with these red lines. I've tried cleaning and re-seating the ribbon cables but no luck! Tried all 4 on the LJ92-01485 board and on the bottom of the panel. Do you guys think it's the board?|

              Colorful LCD Vertical Lines on Samsung ue55es8090
              by Falki
              Hello there, ive recently found an older 55inch Samsung SmartTV.
              Sadly it has vertical lines at the left and one line in the middle-right.

              I have already tested out the connections and have looked at the soldered ribbons of the LCD panel to see if some contacts got loose by pushing them a bit but with no success.
              I have factory resetted the TV as well but also with no luck.

              I am afraid that it is indeed a LCD Panel issue but there are NO scratches or any impact-marks..

              A similar issue has been posted as well but also with no actual response ...

              Samsung Plasma TV with vertical lines (model PN50B430P2D)
              by afex
              This is my 2nd broken TV I'm trying to fix and haven't been able to figure out... currently going without any working TVs so am hoping to be able to fix one..

              This Samsung PN50B430P2D Plasma has this big block of vertical lines which will fade in shortly after turning the TV on. The lines will sometimes flicker a bit or fade in/out and sometimes it just stays present. The length of time it takes them to appear varies, sometimes its a few minutes and other times it appears immediately after powering on.

              I have attached an image of the TV with these bars displaying....
