Hikvision nvr stopped working

[jeffseine]

I have a hikvision nvr ds-7608ni-i2/8p nvr. Everything was working great, then all of a sudden it stopped working. The power supply runs fine, but i can’t access it locally or remotely. Nothing shows on the screen locally. There were no power outages, and it always runs on a ups.

Is it dead? Did somehow the firmware get scrambled and I can reflash it?

Is it dead?

Probably - if you don't even see the logo when powered on, nor the beep.

The power supply runs fine,

How so? The fan turning, or have you measured the output voltages?
It could be a failed power supply, if you are lucky.

I don’t get a beep or the logo.

I think the power supply is fine, because the fans run, I can hear the hard drives run up, and there is a red light that comes on, on the board.

That's a good indication, you're right.

I presume warranty isn't an option?

The way to determine if there is any internal activity would be to hook up to the serial console.
This is easy enough to do - but you need a couple of items :
A serial TTL to USB convertor. A PL2303HX-based one works OK, often sold 'for Arduino'.
A 4-pin 1.5mm ZH JST wired connector, usually sold in 10-packs.
