      You have main board problem, as to what it is at this point I do not know.
      You can try cooling and heating, press on the board, etc. to see if it will do anything.
      You can also check to see which command signal to the power supply board is missing, also try diconnecting the T-Con from the main board to see if the backlights will come on.

          i got nothing with the heating/cooling and pressing on the board. I was thinking main board issue. I'm going to order on and cross my fingers

                      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...

                      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 UN65KU6290F PS board blows fuses
                      by valvashon
                      Samsung UN65KU6290F (May 2017); received from local Buy Nothing group. Was listed as "just went dead" and they wanted it gone. I brought it home, didn't notice anything visually wrong with the power supply board, looked up the cost of a new one and that's about as far as it went. Family was tired of tripping on the foot of the set so I decided to dig in and repair or toss.

                      Can't believe that I didn't check it earlier but I found the main 8 amp fuse blown. Jumped across it with a 10 amp blade style fuse and you can see that it literally exploded inside the second I plugged...
