    LG 47LS4500 No picture, has backlight & sound

    I've tested the t-con's smd fuse, got 11.85 v on each lead. (using dmm set to 200 and with grounding to chassis). The out voltage ribbon from psb to main has all 3 12-volts present. I am assuming these would include the power supplied eventually to the t-con. I've also disconnected each of the panel ribbons, one at a time, and found that when the right ribbon is disconnected, I get half-screen of black with colored lines dispersed unevenly. When I disconnected the other side, the entire screen was back to as it is when BOTH ribbons are connected.(glow/backlit).

    I'd guess a screen/panel fault. Not repairable.

      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 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 UN70NU6900F no picture and no sound
      by jchang
      Hi all

      I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.



      Symptom:
      No picture no sound.
      When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
      No sound at all.



      What I tried:
      1. I tried unplugging the left or right ribbon...

      by ChaosLegionnaire

      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...
