    Samsung ln52a750r1fxza bad picture

    Hello Guys.

    I'm looking for some kind of support with my Lcd Tv.
    It is a Samsung Model LN52A750R1FXZA.
    Every time when I turn on the screen looks like double, specially letters.
    One phrase looks normal side and next to looks like Big one.
    The screen show four horizontals background lines like couple inches tall.
    On the Middle the screen looks black spot.
    10-15 minutes later the black spot almost gone and the images looks little bit better.
    25 minutes later (not all the time), the screen looks better but with a horizontal line crossing on the top like 10 inches
    I put in the pictures and the order start, 10 minutes later, 20 minutes later.
    Suspect for me t-con board?

    What do you think guys.
    Thanks

    That can possibly be the TAB bonding problem, does it change if you the flex the panel?

        Looks similar to the tab bond issue on the Sony 46 and 52 inch KDL series. They use Samsung panels.

        Could be fixed. Mine are still good after 1 year.

          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...
