    55LS4500-UA no video, has sound and backlight

    I had high hopes when I picked up this for $50. I am getting 12 volts on both sides of the t-con fuse. I removed the connectors one at a time from the t-con and took pictures. Any ideas besides a bad panel? I tried another t-con with no change.

      I would say bad panel due to bad TFT drivers.

          UN65TU700DF picture and sound but no backlight. BL tests ok but repl. PSU didnt fix!
          by triplefour
          this tv is throwing me for a loop. do samsung tvs no longer have the backlight self test feature built into the power supply?
          i tested the backlight with my LED tester and it lights up both strips. one of them reads 100v and the other reads 63.7v.
          unplugged mainboard from power supply but left backlight plugged in, and then plugged psu wall power in. expected to see backlights light up but see nothing.
          according to how ive diagnosed in the past, this would almost always be a bad power supply. replacement power supply was cheap like 20$ from ebay. but still i get not even...

          Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
          by Ierwin
          Hello everyone,
          Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
          The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
          He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
          I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
          Anyway I still fully expect that there has been something seriously damaged...

          TCL 65s425 sound/video working, no backlight
          by knoxrebel
          Tv shows no issues other than no backlight. Picture was visible with flashlight and menu navigation possible with audible responses.

          Polyester film Capacitor c620 27nf (on power supply board had visible brown discoloration, but is not shorted. Replaced with suitable spare and now working properly. (Apparently this is a known issue with this series.)

          Backlights tested independently with tester and registered ~140vs on each.

          by triplefour
          TCL 75S421
          PSU BOARD: 40-L402H8-PWD1CG
          it shows not even a flash of backlight when powering up.
          but the tv appeas to turn on and i can hear the sound of the menus moving and clicking. i can power down the tv with the button.
          testing the backlights with my tester all 4 strings lit up and showed similar voltage drops. around 110 or so.
          unplug mb and leave only psu plugged into backlights (PSU + BL SELF TEST MODE?) does not light the backlights.
          i do see 24v but 0v on PSON and BLON (i didnt write this down tho so cant be sure)
          with mb connected, PSON...
