    Sony KDL-40S4100 horizontal image tearing on right half of screen

    hi all. i have a sony bravia 40in tv, the image on it will produce 3 horizontal lines, and the image overlaps itself, and itll happen when the tv has been turned off for some time. also, on rare occasion, there will be no image at all. with the tearing, it will eventually clear itself up when its been on for maybe 5-10 minutes, and all is good from there, until its turned off for a while, or power is removed. the lines are more noticable with darker images.

    a side note, there is also no standby light when the tv is off, but i havent been too concerned about it since the tv turns on and off without it, by button and remote.

    so far, i have already replaced the TCon board, and the main board.

      That looks like a panel tab bond problem. Does the POWER led light when the tv is on?

              Maybe try the "cutoff tape" method, example there: https://www.youtube.com/watch?v=j7vl7-vZEL8

                  LCD panel issue with bad Gate drive which causes the double images you see on the screen, try tape off method as suggested.

                      Sony KD-65x7500D - double image - Tcon or Panel?
                      by rimwall
                      This TV was showing a fine image and pulsing with a partial double image (offset vertically) every few seconds. I taped 8 clock pins on one ribbon cable from the Tcon to the panel. It stopped the double image, but some pulsing in intensity was still visible. I then taped another 8 clock pins on the same ribbon cable and the image is now ‘fixed’. Although I understand this results in some loss of resolution, presumably because the clock signal degrades as it passes horizontally across the screen.

                      I am wondering - do these symptoms and ‘fix’ mean that it’s a Tcon fault or...

                      ViewSonic Pf815 (branded as P225f) Horizontal Deflection Issues - Running out of Ideas

                      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)....

                      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...

                      Sony XBR-65X900F black and white image on one side (fading saturation)
                      by NSkyLab
                      I though I've seen all possible kinds of failures but this one is new...
                      Colors saturation is gradual.y fading out on the left side of the screen (all colors are fading out). While B&W image is looking good.
                      I tried replacing TCon but nothing changed. So this is looking like the panel failure. Is there a chance it can be fixed?
                      Any useful measured can be done on the panel's narrow pcbs? Is there may be something similar to taping trick to fix this issue?...
