    Tv Samsung 32'' LE32B450C4W no picture but sound

    Hello everybody,

    Apologies if this topic has already been discussed over and over.
    My Samsung 32'' (Model: LE32B450C4W) is having, what I think, the common issue of no picture but the sound is still ok.
    The screen is pitch black (no glare on the sides) and I tried the flashlight test. I can see there is a faint image after all.
    I opened the back of the TV to check the caps and they seem to be in a good order, no sign of a swollen top or any other visible damage.
    Do you think it is worth to replace the capacitors anyway or this issue could caused by other factors or components? If so, what is the actual component that is causing this problem?
    The warranty has expired, so I'm taking the risk to fix the TV on my own although I'm not an expert in this sector and my tools and skills are very basic.

    Thank you very much for your help.

    In this model, If you unplug the mainboard form the power supply the back light should go on automatically. If it does you have a faulty mainboard.

        Resolder connections on line of blue caps CI851 - CI865 next to backlight connections.
        Bad connection on any of these cause no picture

          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 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...

          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...

          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...
