Hi all!
I have similar problem.
My device is NVR5216/5232-16P-4KS2E.
It is suddenly stopped working.
It is turning on but not booting up.
I tried to disconnect the cameras and HDDs but it's still the same.
Video of the problem:
I measured the power supply voltage but i am not sure if its the problem.(or i did it correctly)
Video of the measurement:
I hope some of you can help me out. I am super noob on this topic short videos (how to tutorials) would be super helpful or teamviewer/video chat what i would reshare here to help out noobs like me.
Greetings

I made further measurements.
For the board looking fine the voltage, but I could not measure any voltage on the 2 pin cable.

No noise at all.
Do you have any idea what kind of power supply should i use to check if its the problem? From an old pc power supply or something...?

YESSSS!
The problem is the power supply.
Should i buy a new power supply or should i try to fix it?

Good,
Repair power suply must be very complicated and need some tools....
So the beter is to buy a new one, you can find the model on it : DPS-200PB-185 B
Here for example : DPS-200PB-185 B For 190W Delta Electronics Server Power Supply - 365PowerSupply.com - Dell Power Supply | HP Power Supply | Lenovo/IBM Power Supply

I'd open it up and look for something obvious like a cracked solder joint that could just be reflowed. Other than that, circuit troubleshooting a switcher is a bit advanced.

I have already done that. I can not see any obvious damage. My skill set is way too low for a circuit troubleshooting process.
The new PSU is on the way. I will write here if its worked or not.

I would be sure to put the NVR on a good surge protector or better yet, and good Backup UPS.

I got 2 of APC BX1400UI one for the nvr one for my nas. I use them around 1 year.
