    Re: Samsung PS50C450 picture issues

    Measure the Vs and Vsc on the Y-Main Board as Alastair E recommends. The Vsc would be a -ve voltage while the Vs is a+ve voltage.

        At the beginning I did adjustment to Va and Vs.
        Va - was 53, adjusted to 57
        Vs - was 207, adjusted to 211
        Still same problem with picture.

        Andrew F. Ali explained to me that Ve could be also important in that case.
        Ve was 84, adjusted to 88, all problems with picture gone.

        Va, Vs and Ve are now 2 volts above nominals from label (see attachment) and picture is perfect.

        Thank you very much for all support.

                Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
                by TR103
                Hi, I have a Samsung UE50TU with:
                - sound and backlight, but no picture
                - when it arrived, it had a picture for a few seconds
                - it keeps rebooting
                - without ribbon cable between the two panel boards, it does not reboot but I have no picture
                - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
                - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

                - without cable between mainboard and lcd panel and with a jumpered...

                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...

                Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
                by Mgiffune
                I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

                I ordered a supposedly ‘new' Tcon board this time, and                ...

                Samsung QN75Q6DRA, No Picture, Has BL, and Sound
                by Dodgethis
                Hello all,

                This is my first post, but long term lurker on the form learning as much as possible about these TV's. I was given this TV as due to a power outage of constant On/off of power to TV. The TV originally would just click on and off (Typical Reboot Cycle). I opened the back of the TV, and troubleshooted by taking the 96 pin LVDS off one at a time to see if I had a picture on either side. I finally fixed the reboot cycle by finding the error on the left side of the screen off connector CN 1301, and the TV would stay on. Further troubleshooting led me to the driver boards where...
