          so with everything hooked up and tv turned on or just hit the on button, carefully check the voltage of CP803S and the other 2 beside it, dont touch those with your hands, HIGH voltage.

                With everything hooked up the TV can't be turned on, the front red LED no light up, the power button not respond, the remote control no respond. The voltage on main capacitors is 166v.
                I know that this look like a main board problem, but I changed the MB 2 times and everything remain same.
                I disconnected the MB to PS cable and the LEDs light up and I connected the cable back again and the TV work perfect until I disconnect the power cable, after that the TV become unresponsive again.

                    I bought a new Power Supply Board and the TV works correctly. I'm trying to repair the original board and I have the boards side by side connected to the power, every measure until now are the same.

                      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....

                      Compatibility of main boards between different variations of samsung MU6100
                      by JSin21
                      Hoping someone here could possibly help. I have a few questions in regards to compatibility with main boards. But I'll give a quick short run down on what's going on first;

                      I have Samsung Smart TV UA65MU6100WXXY version DA01

                      Now years ago it started intermittently playing up after a lighting strike. Lighting hit the block of units i was living in at the time. Ever since that night the TV started having a mind of its own, It would randomly turn itself off or on, and all inputs stopped responding like HDMI, aerial, but USB still worked. Anyway, over the next few months...
