Old friend was throwing this away after lightning struck their house. Standby power light is on but no backlights will come on. However when I disconnect the main board from the power boards, the backlights immediately come on. This leaves me to believe problem is with the main board. Any help would be greatly appreciated.

Can anyone give insight on what usually means if you have no backlights unless you disconnect main board from power board -

Main board failure in my book. I am guessing that if you measure the PSon pin while turning the TV on it will not change. That voltage is generated on the main IC on the main board.Comment

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.... -
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... -
Hi, I did look everywhere to know if Samsung Y Main boards LJ92-01732A without rev marking is compatible with LJ92-01732A rev AA2.
If they are not compatible why did Samsung give them the same part number to begin with?08-04-2025, 11:35 PM -
Hello!
I just got a Samsung TV model HG75EJ690UB 75" and 4K
. It is a hotel TV, with a slightly different version of the Tizen operating system than the TVs at home.
Being a hotel, it is covered in many functions. With the service menu I can unlock some, but not others. For example, I can't install apps like Netflix etc...
The fact is that it seems that I can replace the main by a, say, "normal". I think the one that corresponds is NU7105, ref BN94-02635. At work, which is a convention center and a hotel, I have many TVs from 55" to 85" that...
