    Re: 40" Samsung lnt4061f Vertical lines no backlight

    the 2.6V seems high, could it be caused by a out of spec voltage regulator? If a T-con expert could give me some advice that'll be great!

        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...

        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...
