    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

      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...

      Samsung QN50Q60t lines on screen
      by jeyoung12
      Hi all
      I have lines on the screen...which is an age old problem that can be remedied by watching Youtube videos and getting out the tape.
      My issue (after successfully fixing a different sammy tv with a separate tcon board and isolating the side of the panel...):

      This tv has an integrated tcon...so it is a bit more confusing when trying to isolate the clocks.
      It has a c ribbon and i have taken each end out to see if that will isolate the lines. instead, it makes it much worse ALL over the tv!

      So....i don't know what end of the C ribbon to work with...
