    Hi All,

    Had a lightning strike that tripped the breaker supplying my HIKVISION DS-7608NI-E2/8P.

    All of the POE ports are now dead, i.e. no lights blinking. Have checked the cameras and they work independently of the NVR. Disassembled the NVR and see no obvious damage.

    There really isn't much inside these. Was hoping there might be a supplier for the circuit boards, as the unit isn't that old. Or if anyone could offer other tips to look for the problem, I'd appreciate it.

    Forgot to mention, the unit powers on just fine, goes through the full boot process with no problems, just won't display live view cameras.

    If you have other method to power all your camera like a stand alone PoE switch, try plugging the NVR LAN port into the switch and see if it detects the cameras again.

    POE board may be fried but the main board could be okay still.

    I don't have a stand alone PoE switch, but I see your point, it would be a good way to test the board.

    Try a factory reset as well so you know your staring from point a, all settings like the internal poe ips addresses are back to 192.168.254.1-8
    sad as an eight port poe switch you will lose one via the nvr to the switch if your running eight cameras if less your ok

    Worth checking would be that the 48v feed from the power supply is still working. It's only used for the PoE board.

    I recently swapped out the PoE board for a spare I had (from a bricked NVR, I first bought the chinese edition, then the English) and it's working great. IT was real easy to do as well, as you probably realise. So, proof of concept.

    If you can get a camera powered, maybe with a 12v supply, and wire it to the LAN instead of the NVR PoE port, you can at least confirm that the main functions of the NVR operate normally, before going to the cost of buying a POE switch.

    After testing, I'd rather replace the POE board than use a POE switch.

    But, Does anyone know if there is a supplier for these particular POE boards?
