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
Picked up another TV. Samsung UN43NU6950FXZA. No power and no standBy led on. Removed back cover and:
Main fuse = OK
Back light LED = OK. Power them with aux power source
LED output = OK 156V
I do get 12 V DC out of the power supply going to the digital section but no 5V or 3.3V. PS_on voltage is only 1.8V. I have looked everywhere on the PCB , I could not find i reference for 5V output.
Also removed connections to panel, speakers and remote but no luck. One strange thing is that even with the LED power supply working, backlight LED do not turn on...07-20-2025, 08:06 PM -
Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same... -

Hello,
I have an HP 15-eh1070wm laptop that came to me for the same reasons I am starting this thread. The charging LED appears when the laptop power adapter is connected and the power LED appears when pressing the power button, but nothing appears on screen.
First thing I did was take off the bottom panel and remove the battery and then press and hold the power button for 30 seconds and then reinstall the battery and power on. The fan spins and this time, the back light illuminates and a brief message appears on the screen for about 1 second saying something along like,...
