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.... -
Just starting to crack into this one and wanted to get the ball rolling.
At power on (plug in), power light on, relays click, repeat (sometimes)
After disconnecting Y-Main from SMPS power stays on and boot up jingle is heard from speakers
Removed Y-Main for inspection and testing

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... -
Hello, the problem with this TV is it has all the Y and X voltages, but does not produce any image.
It had a TON of cracked solder joints on these boards, fixed all that I could find, but in the last test I forgot to plug in the Y-SUS to control board flat cable, it was left dangling and possibly some pins shorted to the panel metal ground, the X-Main buzzed quietly then blew up in 3 seconds after powering up, annoying.
Two RJH30E2 shorted, they are 360V 35A 1.7VCE IGBTs, the problem is I don't have any 360V IGBTs, only 300V or 600V, would two RJP3065 fit in? It's...
