I have been all over site, web, tech support etc.
they will not provide me info related to motherboard diagnostics.
was on line with support, they stated motherboard was culprit.
advised to take it to a repair man and they could fix as is out of warranty.
DVR is powering up but will not load, there is a red led lit on board (led #4)
looking to see if i can resolve myself?not having luck identifying motherboard either.

I've tried everything I can think of.
both forum spots are dead ends.
most do not dive that deep into troubleshooting.
tried to google motherboard and had no luck.
mac address comes back to company in china but again, no luck on info.
system is a Q See 814 4 channel nvr/poe 1tb HDD
will not post/beep on power up.
12.5vdc and 47.2vdc inputs OK.
do not know much beyond there
thought one of my fellow supporters would have an idea

"that's the coin cell battery right?"
Yes. You can get them at Kmart, BigW etc, etc.

Or, take one out of an unused comp.
