    Samsung 55" LCD TV LE55A956D1M - No picture

    Hi

    Looking at a Samsung 55" LCD TV LE55A956D1M with no picture, backlight is on and seems quite bright but no picture. Tried a factory reset with the remote and makes no difference. Makes the normal startup and shutdown chime. I was thinking it was a faulty main board and noticed its got a dimming board above the mainboard which I've never seen before. Looks like the main board is almost impossible to find (BN41-01063A) but the dimming board if freely available. Anyone any experience with this model of TV and could it be a faulty dimming board ? See attached photos.

    thanks

    Mal

    How about the pictures of the whole backside of the TV to show all the boards?
    The board in second picture looks to be the FRC (Frame Rate Conversion), the output is then fed into the T-CON board. You need to find out if you do have VDC to the FRC board and the T-CON or not.

      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
      by Tynan Dill
      I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

      Upon bringing it home and plugging it up, it showed a standby light.

      I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

      The screen seems to blackout and stay black, but with a flashlight I can see the display.

      With my Playstation 4 connected via HDMI, and running a game I can hear sound.

      Assuming...

      HP Pavilion 15-eh Board DAG7HAMB8F0 - CPU throttling to 0.4GHz (PROCHOT_EXT) and black screen

      Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
      Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

      Upgrading a Samsung ue55nu7096u with logic board from an ue55ru7105k -- good idea?
      by ohren
      I hope this is the right forum to post in despite not technically being a repair, but still a question of swapping boards.

      I thought I'd explore the possibility to upgrade an existing working Samsung ue55nu7096u with the logic board (and power board if needed) of a newer model (ue55ru7105k) of the same size and appearance (and resolution). The reason being I'd like the extra inputs of that board including component in, an extra HDMI port and bluetooth. Its panel is broken so I have no use for the board otherwise.

      The models launched in 2018 and 2019 respectively....

      Samsung UN55H8000AF - No Picture, Working Backlight, Replaced T-Con Board
      by ermals
      Hi all!
      I've recently run into an issue with my Samsung UN55H8000AF LED TV displaying no image. I've done quite a bit of research in terms of what could be wrong with it. Below are the steps I've taken prior to reaching out here for some assistance:

      1. I've tried replacing the T-Con board (BN95-01594A), twice and have still experienced the same issue with all the boards I've tested with.
      2. I've tried to remove one side of the ribbon cable that goes from the T-Con board to the panel and still not getting any image on left or right side.
      3. I've checked voltages...
