    Samsung HP-R4252 pink/blue lines, coax okay after 6 min

    Hello, this is my first time posting here. I found this site via a link to tom66's outstanding guide on troubleshooting plasma tv's.

    One day pink and blue vertical and horizontal lines started appearing on the screen for all inputs. After a few weeks it got so bad that I couldn't see any picture at all, except for coaxial inputs. Now if I wait about 6 minutes, and press a button that brings up a menu (like the guide) the lines get erased and the picture is great until the TV is turned off. This doesn't work for any other input.

    Here is a video of the problem, and it going away after 6 minutes and pressing the guide button:

    I would really appreciate some advice from the forum on what might be the problem.
    Thanks in advance,
    Joe

      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 55" UN55JS9000 - Pink vertical lines due to chipped LCD panel?
      by Anonmis
      Hello all, I was recently repairing my Samsung 55" UN55JS9000 tv from the common burnt backlight LED's and cracked light guide panel issue. After replacing the LED's and putting the TV back together, I tested the tv and all I was getting was sound but no image. Somewhere along the way (could be related to the next issue) the T-Con board became damaged and after replacing it I have made a little bit of progress but now have bright pink vertical lines and still no image.

      The bigger issue .... I took the TV apart again and realized that I likely didn't sit the LCD panel correctly...

      LCD TV Green/Pink screen problem
      by jimjoe123
      I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.

      Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.

      Then each time...

      Screen Display Vertical Multicolor Lines
      by Stanley1843
      Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed...
