    Samsung Plasma HP-R4272C, picture horizontal lines

    I got a Samsung Plasma TV, model HP-R4272C, sound is good, but pictures look like many horizontal lines, but 1/6 of the horizontal is good as shown in the picture.
    I checked the VS,Va, all good. There are two y-buffer boards, each has three cable connectors as the second picture, I disconneted and connected them but not help. When touched the heatsinks at the y-buffer boards, the good picture position (The first of the lower buffer), the temporary is acceptable, but all others are very hot.
    Questions:
    1. Does this mean the y-buffer boards are bad? or the y-sustain board problem. Which one I should replace?
    2. Does this mean panel is bad ? But 1/6 of the screen looks good.

    Thanks

      It is most likely bad buffer boards.

          Sony XBR-85X950G Gray horizontal lines and vertical picture shift diagnosis?
          by noisykid
          5.5 year old 85 inch Sony Bravia X950G started showing gray horizontal lines across the bottom of the screen and the picture shifts slightly vertically when it happens. The lines sometimes get bigger/smaller vertically and bounce back. See the video for the problem. It seems to be happening after it warms up after an hour or so. Happens regardless of source. Right now there's nothing but power cable connected and it's happening. We did hook up a new Nintendo Switch to our HDMI switching receiver today, and played for a while with no issues, but this problem didn't occur til a few hours later while...

          TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
          by howardc64
          All left and right refers to looking from rear of TV (or looking from front with TV upside down)
          • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
          • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

          Samsung QN70Q6DTA Ghost or horizontal lines after tape fix horizontal line
          by Ihandyrepair
          Hi guys

          I just started fixing 4k TV few months ago. so I am still learning a lot
          I got this tv from friend complaint is ghosting or horizontal lines on image.

          never saw the original symptom but I took the tv back home. the funny part is that after bringing to home, the tv worked fine no issue for 3 weeks.
          then it started to show the ghosting white image.
          I started using the tape method, but this tv does not have a T con board and it has only 1 ribbon cable from main board to the tv panel.
          it has 3 thin small boards at the bottom of the...

          Samsung plasma 50" TV, model PN50C540G3F, has black horizontal lines
          by CyberNinja
          First, the black horizontal lines even overlay the TV's menu. Does this behavior indicate that it's the plasma panel that's defective? If not for the black lines, the TV works just fine. I've cleaned the 6 connectors between the panel and the Y-buffer board, causing no change in the black lines. Visually, the 12 ICs on the Y-buffer look brand new (no holes, etc.). I put my fluke meter in continuity mode and tried to perform the "short" test on the 6 panel ports and found many shorts. But I don't think I'm doing the "short" test correctly and I'm hoping someone can provide guidance....

          Hitachi 55HDS69 55" Plasma TV - No Picture But Sound
          by KYBOSH
          Picked up a bahemoth plasma TV not too long ago and just now getting around to looking at it.
          No picture but you hear the TV static (white noise) playing loud and clear.
          The back was already taken off (and no screws were provided) as the previous owner had already taken a look.
          But it seems they didn't get too far and just left it.

          When I first took a look I was amazed at how pristine the inside looked.
          Its as if the TV had been in a time capsule.
          Caps looked like they were just pulled off the self.
          Copper coils had no sign of corrosion on...
