      These are know to have the main BGA chip fracture the solders and can cause all sorts of weird faults like lines, loss of inputs like HDMI etc.

      Could try heating that chip up and see what happens.

              HI, it seems a lost of Horizontal clock, it's much probably a panel fault unfortunately, can you make a photo of a good monitor and the broken tv showing the same image from PC vga? (one at a time).. you can dismantle the screen, putting apart the plastic and metal bezel, then put pressure on the outer screen flats R and L side (those glued on glass) and seeing if image restores. BYE.

                  Thanks everyone, tw2005 nailed it...I heated the main BGA chip and it cleared up the horizontal lines and restored the video.

                      TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
                      by howardc64
                      All left and right refers to looking from rear of TV (or looking from front with TV upside down)
                      • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
                      • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

                      Note: apologies I initially posted this request for help in the wrong forum! I am reposting it here and will take down the original posting.

                      Hi Everyone,

                      I've been working on repairing this beautiful CRT monitor off and on for the past several months and I'm really at a loss for what might be causing the problem.

                      Unlike other common Horizontal Deflection issues which result in a steady vertical line, when I turn the monitor on, there is a pulsing (somewhat segmented) vertical line. I've attached a photo that shows the issue (difficult to capture without video)....

                      Samsung UE70TU7020K Which lines to tape on a bad panel
                      by learnmore
                      Hello Community,

                      I'm working on a Samsung UE70TU7020K.

                      It looks like a bad panel. There is only 1 FPC cable from the Tcon (built into mainboard) to the panel.

                      I'm using a piece of tap a few mils (covers about 8-10 pins), at different locations and have had varying results but nothing that is remotely watchable (multiple lines across all the screen, half screen and total black out on screen). The buffer board is divided into 3 boards. I've disconnected the end board one at a time but each time the screen was totally black. I presume it's because the potential...

                      ASUS VA27EHE randomly unstable
                      by Sharx112
                      Hello community. I've got an ASUS VA27EHE with a Panda LC270lf1l01 panel that started to behave strangely. A bit of intro:
                      If you power on the monitor without any inputs it turns on, displays the ASUS logo, shows no signal and goes into standby normally. When you plug it via HDMI sometimes and more recently, most of the times, it distorts the bios logo with horizontal lines, then when loading into windows 50-50 the windows emblem also is in horizontal lines. And after the system loads it almost always works properly, lol. On some rare occasions a part in the top of the monitor is being distorted...
