I have a Samsung lcd tv model LN37A550P3F that has a flashing power light on front of tv, I have taken off the back of the tv and looked at the power supply, I see no bulged or leaking caps, I try to turn it on and there is no clicking sound from power supply board but the blue glow light on the bottom front of the tv comes on and that's it, the power supply board is BN44-00216A

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.

As the Elitebooks (820, 840 all gens) only show flashing Power LED and flashing CapsLock (continuously) + a very soft "ticking" noise near the DC Jack,
I wonder if re-flashing the BIOS might be of any use here.
As far as I understood, steady flashing either means insufficient power or a CPU/GPU/Motherboard issue. I use the original 65watt power supply.
There are so many threads out there, but most of the solutions involve flashing codes, which I dont have or claim that you MUST use the original power supply, do a hard reset, reseat the RAM, clean the RAM,... -

un65tu7000fxza - I am experiencing the flashing red light on the power led. So I purchased the replacement kit for the mainboard and power supply. I still experienced the flash red power light. So I purchased a new ribbon cable, The flashing light stopped for a minute, I could hear sounds on the TV but no picture. I did the 60 second reset and it went back to flashing. What could possibly be the issue now? All the LEDs are lit up from what I can see.
Thanks for all responses.
