    SAMSUNG UE43AU7020K BACKLIGHTS BUT NO PICTURE

    Hi
    Really stuck on this TV
    I'm thinking it's a bad screen ?
    Voltages all seems good
    Tcon 12v ok
    Remove one tcon cable at a time no half image on the screen just backlight and no picture
    even tried the tape trick still no luck

    Thanks

      If I disconnect lvds cable one at a time on the tcon
      CLK1 to CKL10 is 9.8v
      If both lvds cables are connected then
      CKL1 to CKL10 is 0.00v

          maybe the spi flash on the tcon bad, they are prone to be polluted, try at least a replacement board..

                      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 UN70TU6980FXZA no sound no picture but does have backlights
                      by stinger
                      When I turn tv on, the backlights come on but there is no sound or picture. I have read that these tv's have problems with the panels going bad but the "no sound" has me questioning if the main board is bad. Is there a way to troubleshoot the main board to determine if that is the problem?

                      Samsung LCD TV no picture backlight on no 12v at tcon
                      by shelby5041
                      hi
                      i have a samsung lcd tv

                      it powers on with sound and backlight but no picture

                      all voltages from PS are good 12v 3.3v and 5v

                      whats odd is that at the tcon i tested voltage across the fuse on the tcon and i get 0v

                      i figured main board issue..so i ordered a used main board....when i put replacement main board in i still have same issue

                      no 12v at the tcon fuse

                      i disconnect the panel ribbon cables to rule out any panel issues and i still have no 12v at the tcon fuse

                      the odds of having 2...
