      Re: samsung not working

      The blinks mean nothing on a Samsung TV. They are normal. Have you checked other faults, like to make sure the PSU voltages are OK and if the backlight will power on by unplugging the connector between main board & power board.

              Something wrong on main board, check volt regs, and the CPU core voltages. Could be bad firmware.

                              Samsung Power Supply Board BN44-00874F
                              by Nicktronic
                              Hey everyone,

                              This power supply board is hard to find but there are repair kits available. This board had a blown fuse, FP801S, blown PFC MOSFET, QP802CS and ceramic cap, CP809. I replaced them with parts I already had and tested the rest of the parts that would've come in the repair kit and they were fine. I powered the board up on the bench expecting, in typical Samsung power supply board fashion, to see all my output voltages but, nothing. 0 volts on CNL801, CNM801 and CNT801. The only thing I have is 170vdc on the filter caps. No standby voltage either.

                              Anybody...

                              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...

                              Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
                              by Asraf Atb
                              Hi everyone,

                              Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

                              Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

                              I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....
