    Vertical Lines -- Bad Picture -- LG 60PA6500

    Hello everyone!

    I just got done replacing the control logic board on my LG 60PA6500, checking all the caps on my YSUS with an ESR meter, and replacing the Y-Buffer boards.

    I have these bad spots where the picture is terribly messed up. What do I do?!

      Cry.

      Good chance the panel is faulted on the flexible ribbons at the base, there's a chip embedded which fail or burn out.

      Is this the original fault and why the ctrl bd was replaced? Tried the auto-gen test patterns on the ctrl bd?

          The original fault was the "no picture, only sound" issue. Unfortunately, it has evolved into this now...

              check the bottom edge boards on that side... especially where the tabs attach to the boards. Maybe someone "washed" the screen and caused the "initial issue". The connection areas along those boards should be clean / similar. But as was suggested, "crying" might be your only choice... that and selling the boards that you bought / know work.

                  SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
                  by JJAAMM
                  This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

                  Problem
                  TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

                  Sony XBR-85X950G Gray horizontal lines and vertical picture shift diagnosis?
                  by noisykid
                  5.5 year old 85 inch Sony Bravia X950G started showing gray horizontal lines across the bottom of the screen and the picture shifts slightly vertically when it happens. The lines sometimes get bigger/smaller vertically and bounce back. See the video for the problem. It seems to be happening after it warms up after an hour or so. Happens regardless of source. Right now there's nothing but power cable connected and it's happening. We did hook up a new Nintendo Switch to our HDMI switching receiver today, and played for a while with no issues, but this problem didn't occur til a few hours later while...

                  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...

                  BenQ 2765HT vertical lines, no picture
                  by hendue
                  Hello everyone,

                  I was trying to fix the monitor, which was giving me the following pictures:

                  It was somehow reactive, such that if I pressed the buttons, the lines changed in positions or if i moved e.g. a task window, it would somehow change the patter, too.

                  I swapped out the mainboard without any luck. So I thought that it has to be an issue with the panel itself and was trying to assess whats wrong on the control board of the panel.

                  Somehow, I managed to short the LVDS protection with a MOSFETS cooler on the PCB.

                  I turned around...

                  Insignia NS-50DR620NA18 w/ large vertical lines & no picture
                  by srs
                  I'm not sure what to do next and came here since y'all helped me fix a 50" plasma TV back in 2014, which is still working!

                  A friend gave me an Insignia NS-50DR620NA18 50" TV that suddenly developed large vertical lines on it. He said he had no idea what might have caused it and has replaced it with a larger TV. He was going to throw it away.

                  I did not notice any bulged or leaking caps on any board, the voltages produced by the power supply match the voltage that the pins are marked. The backlight leds are working. I have tried cleaning the ribbon cables...
