Then you will need to check the FETs that it protects.

I had 3 42" Samsung hp-t4254 and 1 hp-t4264 and 2 hp-t5054 and 2 hp-t5064 that I replaced the 6 1000uf, the 2 470uf, and the 2 2200uf caps and all 8 of them fired right up!
Hope this helps someone!Comment

Hi All,
First time posting here ... my name is Kevin but my friends call me Journey.
I have a Samsung 75" LCD model UN75RU8000FXZA that I don't remember the original fault other than it wouldn't power up anymore.
After it sat for many month's I decide to look at it again. The motherboard seemed to have power regulation issues. After much fussing I decided to just get a new MB.
It came a few days ago and I installed it now just cycles the power relay on and off ... when on the backlights light up and then dim and then relay kicks off and the whole things starts again.... -
Hi all!
I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅
I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

Hi everyone,
I am dealing with the problem of turning on and off my Dell e7470 notebook.
The battery charge light is solid white, I press the button, the power indicator and the light on the button are solid for 1-2 seconds and immediately turn off.
The system does not turn on, there is no post.
I removed the RAMs and changed them, changed the battery, RTC battery, AC adapter, removed them and waited, tried again, it does not turn on.
The problem continues in the same way.
I tried to turn on the Fn key, nothing came to the screen.... -
Hi All,
Need help.
I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.
So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard.... -
Hi. First time post. I've scoured the previous forums looking for info - there isn't much for my model
UN65MU8000FXZA
We had a power outage. Everything plugged into the Monster surge protector seems to be fine except my Samsung TV. It was dead when the power came back to the house.
Here's what I've looked at:
Unplugged main board from power supply - BACKLIGHTS COME ON.
Ordered new main board - still didn't work. Not sure if used MB was DOA
MAIN BOARD = BN94-12295K
PSB= BN44-00912 L65E8NR_MHS
There...
