by PantherDaveHi 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.

I also think my parents said there was a thunderstorm and the TV failed after that.
Section 6 in the service manual talks about power and no screen,...10-30-2024, 10:09 AM -

by russpallHi there,
I've got a 39" LG 39LN540V that's just spontaneously stopped working! The symptoms are - when I plug it in, the red light will flash on twice, then go out, there's no visible picture, and I couldn't see anything using a torch on the panel either. If I press the power button (either remote or on TV), the red light comes on continuously. If I press power again, the red light flashes twice.
The TV is using a power board EAX64905301. I've attached a diagram of the power output, I've tested the voltages with a multimeter and I'm getting the following:

There's two other threads about this monitor with seemingly the same problem. The problem was resolved in one case by replacing the entire PSU board and in the second one by replacing an unknown IC.

The first one has pictures of the pcbs and I noticed that there's one IC and assorted caps not populated on mine (but the PCB itself looks identical) so I thought that'd warrant a new thread.
It's my dad's old monitor. He...-
