DVR shutting itself down after a few seconds.

[iker höek]

Hello.

I've had this DVR for some years now of light use and it just started doing this.

It would turn on as normal, but shut itself down after a few seconds, before the "recording" LED gets lit and after the normal 3 short beeps, and the nothing until the next power cycle. Of course the next power cycle it just does the same.

I already tried:

1. Turning it off and on again.
2. Replacing the SD card.
3. Flashing the BIOS again.
4. Reseating all the connectors.
5. Pushing the reset button.
6. Checking the fuses.
7. Powering it on with a power bank and a micro USB cable (it does exactly the same)

I cannot connect wirelessly because it shuts down before I even find the network.

What are my options?

Thanks!

Switch Rear camera with Front camera, to see if it can reboot or not?
If it can reboot, it indicates that its front camera was faulty!

Hello.

Sorry I took so long but I was waiting for it to fail again, but it hasn't.

I don't know if a failure in a camera could come and go but if it fails again, I'll swap the out to check and report back.

Thanks!
