    Thomson 32LM051B6 flickering vertical lines/dots.

    Hi,
    Any ideas what's wrong with this Thomson TV? On menus the picture is fine, but when there is signal applied to any ports the picture is full of flickering/flashing dots.
    AOC L32W551T is probably the same TV. PSU is full of Chemicons.

      I think you need to check the capacitors on the main board about low voltage stabilizers.. and PSU

          Here are pics of the boards.
          I have started measuring the ESR of the caps on mainboard, but haven't found any bad ones.

              Clean and re-seat all connectors.

                          I cleaned and re-seated the connectors but that didn't repair the problem. I also tried to heat the main board while the TV was on but that didn't make any difference

                              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...

                              ACER BM320 Monitor - Horizonal Flickering Lines After a While
                              by reessi
                              Hello,

                              The monitor started off showing flickering thin (1 pixel) lines horizontally every say 3mm..

                              They are black on the right and gradually fade to nothing on the far left.
                              They start either after 5 mins or up to 2 hours after so annoying for testing.
                              They flicker continuously very fast! With a slight pause milli-second every second.

                              Initially I cleaned the LVDS cable and connected to the T-Con and then it worked fine for 3 weeks but not sure if this was just co-incidence.

                              I tested each half by removing the first the left flex from...

                              Hi guys…I need your help. My cousin ask me to fix her tv. The tv when I went to pick up showed 3 horizontal black line. So I know it was a bad panel issue but I could try to fix with the tape method so I said her I could fix easy. When I come back to home, I turned on the tv and now the tv show vertical line colored….and the problem is that I unplug the ldvs cable, first the right side then the left side I still have the lines. The lines never disappear. When the right side is plug in I don’t have nothing on the screen only this vertical lines, when the right side is unplugged I have picture...

                              Colorful LCD Vertical Lines on Samsung ue55es8090
                              by Falki
                              Hello there, ive recently found an older 55inch Samsung SmartTV.
                              Sadly it has vertical lines at the left and one line in the middle-right.

                              I have already tested out the connections and have looked at the soldered ribbons of the LCD panel to see if some contacts got loose by pushing them a bit but with no success.
                              I have factory resetted the TV as well but also with no luck.

                              I am afraid that it is indeed a LCD Panel issue but there are NO scratches or any impact-marks..

                              A similar issue has been posted as well but also with no actual response ...

                              Help. Sony kd-65x85dj vertical lines
                              by visionbluedemon
                              First. it has no picture at all. i solved it by covering the ckv lines using tape to to block the connections

                              Second. now has picture but with vertical lines that follow the image. tcon board ic overheating

                              tried blocking LC lines too, but same results



                              is it lcd panel issue or tcon board issue?...
