    Samsung UN55E46000 has sound but no picture

    Good day, I am hoping for a little help narrowing my problem down. Currently my Samsung UN55E46000 is giving me some difficulty. Mainly there is no picture, when i turn TV on i hear the start up sounds but there is no picture.

    I have taken the back panel off and checked for bad caps but do not see any. Voltages from power board to main board are all OK based on the posted voltages, and the fuse has been checked to be fine.

    I was initially considering the inverter board, but I have noticed the following oddities that are making me consider it is the main board (BN41-01778A)

    1. TV turns on as soon as it is plugged in, and power button has only turned it off once after about 20 attempts. With the cover off I can also see that the backlight is working fine, as this comes on as soon as you plug in the TV and does not shut off until you have unplugged it (can't seem to get power button functioning properly)

    I do not want to replace both boards if I do not have to and I am leaning towards replacing the main board (BN41-01778A) before the inverter board (V546HK3-CPS1).

    I will try to post pictures tomorrow but I do not think they will help much, nothing is visibly wrong with either boards and I have checked and reseated all connectors. Any advice would be greatly appreciated!

      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 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...

      HP Pavilion 15-eh Board DAG7HAMB8F0 - CPU throttling to 0.4GHz (PROCHOT_EXT) and black screen
      by m1ch43lzm
      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...

      Samsung UN65js8500F, no sound, blank screen and T-Con board with one LED on
      by mrtek
      Hi I am new to this kind of repairs but I want to learn..I have a Samsung UN65JS8500F. the TV used to work and I tried to fix darker areas in the middle only ( img 1,2,3). I thought the led strip were bad..not the case. I did not research in advance what kind and where the LED were located. In this model they are located vertically on right and left side. Took the TV apart and put it back together. Now the tv shows no welcome screen and no sound is available thru the speakers. ..just a black screen..Backlight LED do turn on...also noticed a 5 blink code , not sure if that was there before. I can...

      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....
