    LG 50PC5D Plasma Screen issue Left side is white with colored lines

    Hi all,

    I have this plasma TV that I repaired a couple of years ago (bad capacitors on the power board). I am having a different issue now.

    The screen went out on the left side (looking at the screen). It is mostly White with spaced lines (line colors are Red, green Purple and Red). When it first started it would sometimes be mostly black with the colored lines. It did happen to work the next day for a few hours or more, then reverted back to the issue where it stayed.



    Pictures included: (Looking at the back of the TV, the right side is on the right which is the same as the left side if looking at the TV from the front) Picture 8 is labeled with the connectors that I unplugged. Only one cable was unplugged at a time. Pictures 1-8:

    1. Problem that I have. Untouched.
    2. Rightmost 'power' cable unplugged from bottom board (see pic 8 for details)
    3. Right most 'power' cable unplugged (another view)
    4. 2nd to last right 'power' cable unplugged from bottom board
    5. Flat ribbon cable (right side) unplugged.
    6. All plugged back in and reseated. Same issue.
    7. Back shot of TV electronics.
    8. Close-up of back right side and labeled to correspond with the numbers above.

    I have checked all voltages and they seem within range but I am in the process of re-checking ALL of them just to be sure. This is all of the clues that I have right now. I can only think of three possible problems:
    1. Panel is bad. (Hopefully not as I get different results when different cables are unplugged.
    2. Control board is bad. I need to find a better way to test it.
    3. The long board on the bottom is bad. I need to find a better way to test it.

    Any thoughts? Any help will be appreciated!

    My vote would be for a bad control board; the evenly spaced vertical lines make me lean that way. I don't know of a test for the control board.

      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

I give you the photo of the panel, and the panel with the left ribbon unplugged and then the right. Thanks for your help...

      Vizio V555-H1 - Horizontal lines then double image bursts
      by jason123
      Hi there,
      I think it might be a bad panel but I thought I'd ask before I chuck it..

      thin colored horizontal lines bottom and thin section on top. As it runs warmer, you can see some ghosting or double image. Right hand side of the screen darker then brighter (backlight is always on, so it's the actual LCD that gets darker and brighter)

      Replaced the Main board, because I had one handy, no change.

      Is it worth replacing TCON? disconnecting ribbon on one side of the panel, the lines appear still on the other side (unplugged side.)

      Vizio V585-J01 dancing lines and image doubling
      by x_orange90_x
      I got this tv yesterday and it shows a screen full of colored vertical bars and horizontal lines that move, change, and dance around. When the set is powered on there is a slight buzz from the tcon. I removed one ribbon at a time and this was the result:

      Right side connected, left side disconnected = half image on right (somewhat distorted, see photo attached) white screen on left. NO buzzing from TCON

      Left side connected, right side disconnected = right side black, left side white with distorted horizontal lines near top of screen. Buzzing from TCON

      I swapped...

      Vizio M58Q7 colored horizontal lines
      by rapid911
      Hi guys, I have a Vizio M58Q7-J01 and now there are some colored horizontal lines on the screen. Could someone tell me if it's probably a panel issue or something related to other parts and can be fixed? Thank you in advance....
