    Samsung UN55C7000WF - vertical lines on screen

    I have a working Samsung model UN55C7000WF that has two small vertical black lines down the middle and then a bunch of them on the right side. I've attached pictures of the two locations. I haven't taken it apart yet and thought I'd see if anyone knew what could be the cause of this i.e. capacitors, power supply, buffer boards, etc.

    Thanks.

      Power down the unit, with the remote hit in sequence MUTE,1,8,2 and power on the TV.

      This will put you into service mode. I think for these panels select the SVC menu option and run the test patterns.

      DDR PRE/POST
      FRC

      LOGIC

      If the lines are present on all tests you can run then its going to be the panel. I am pretty sure its the panel anyway as I have had 2 of these fail with lines like that. BUT never hurts to check anyway.

          Almost certainly a bad panel. Another Samsung with bad LCD panel.
          Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
          For service manual, schematic, boardview (board view), datasheet, cad - use our search.

              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 LE32C530F1W with vertical lines on Screen
              by Kambi13
              Hello all, I'm dealing with a Samsung LE32C530F1W that now has vertical lines on the right side. It started with a ghost image on the top of the screen and then I tried the old trick of masking a few contacts in the flat cable that connects the T-Con board to the screen with some tape. It worked for a while and now out of the blue it turned into what you can see in the pic. I was able to get my hands on a known good T-Con board but the problem still persists. Now, what I've noticed is that the cooper colored flat cables that are directly connected to the screen itself are very hot to the touch...

              LCD SAMSUNG LE40A656A1CXXE - Vertical Lines on Half of The Screen?
              by ItalianSat
              Hello Everybody,

              I have a 40 inch LCD SAMSUNG LE40A656A1CXXE. Its problem is that there are Vertical Lines on Right Half of The Screen.

              Interestingly enough, when I move my mouse (in the case if connected to a PC) or when I am watching the TV, lines also move. At first appearance, I had thought that the problem might arose from loose vertical ribbons (COF), but when I opened up the TV for further investigations, I realized that the problem cannot be solved by touching them.

              Moreover, I detached the T-CON board for a new round of investigation. I personally...

              1/3rd of screen black with occasional vertical lines - repair attempt for learning! - Kogan KALED58RT9220SVA
              by Firentiosi
              Thanks for offering your assistance with this. I'm an electronics enthusiast with moderate level of competence (have a decent lab with two power supplies, microscope, DSO, hot air, good iron, can competently work at a component level on SMDs, design and solder own PCBs etc). I really enjoying fixing things and learning new stuff so took up a free 58" LED TV and have been googling and watching Youtube videos to see if I can fix this! I am happy to go down to individual component replacement/strip replacement etc - it's all in the name of learning.

              The issues are as follows: the...

              Samsung UE55JU6800K half screen dark
              by Chrissygizmo
              Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
              I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...
