    Samsung LCD LE40R86 vertical lines problem

    I have problem with LE40R86. I changed couple bad caps and now i can turn it on, but i have only vertical stripes on screen and after couple minutes i can hear clicking relay which turning off and on tv. I read about it and someone says that it could be problem with firmware on ic1803 (24C256).

    I have programmer, but cant find bios. So where can i find it?

    Or anyone have idea what else to do?

    thanks

      What caps have you replaced and what caps have you used to replace them?

      Can you post some pictures of the problem and all of your boards. Use the manage attachments function to upload pics.
      Do NOT touch heatsinks when testing for voltages as they may be LIVE!

          Please check the voltage regulators on the T-con. I repaired an LE40R74 with the same problem. Did you get TV as faulty or did you own it when it went wrong?

              Woah. Problem solved.

              Sorry guys, and thanks for fast reply.

              I bought faulty tv one month ago, and like i said i changed couple caps on power supply board. After that tv turning on but i had vertical lines. I tried with new t-con but had same problem.
              Last night i found some firmware and reprogramed 24c256 with my top853 programmer and thats it - problem solved.

              Original remote doesnt work, probably coz wrong firmware but with universal remote it works.

              I hope that my solution can help someone else too.

              Cheers!

                  Samsung UN46C8000XFXZA vertical bars/horizontal lines
                  by x_orange90_x
                  I posted about this previously but didn't get any response, and I have some troubleshooted a bit so I have more info.

                  The screen is full of horizontal "gaps" or lines that distort the picture badly, and after about 10 seconds of powering it on the screen starts to fill with red vertical bars that take on the horizontal pattern. After the screen filled with the red bars, they instantly vanished and then slowly started to reappear. I initially thought it was tab bonding failure, but after getting down to them and pressing each one I find zero change in the picture. I went...

                  Thin stable coloured vertical lines on Samsung UN65NU6900FXZC come and go
                  by polaro
                  Greetings,

                  I've bought a used Samsung UN65NU6900FXZC LED TV. It worked fine for some time and then developed, at first, a single very thin (1 pixel) vertical stable blue line, from top to bottom, close to the left edge of the screen. Now it's 3 lines on the left. When I connect HDMI sources the number of the thin lines grow. After disconnecting and cold discharging I am back to 2 lines. The lines disappear at a rate of 15-20 minutes per line. So it does not look like a damaged LED panel. Any advice? Thanks...

                  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...

                  Samsung LA46A950 aka. LN46A950 - intermittent vertical green lines / distortions
                  by 265chemic
                  Hi All,

                  I have a Samsung LA46A950 that intermittently was displaying issues with evenly spaced vertical green lines only on dark / black areas - this has progressed to more often and blue lines sometimes, as well as a little image distortion.

                  My initial suspicion was the T-CON board, which I took out and cleaned but the issue persists. A heat gun on all of the control boards makes no noticeable change. Ive also reseated the T-CON to panel ribbons (4 of them) and moving them while the panel is on doesn't seem to change the issue.

                  Below are some photos...
