What's the device status?

If the device is 'bricked' - ie no longer boots properly, the best method to re-apply the firmware is to connect to the serial console.
This is available via a 4-pin connector on the main board.

To do this you need :
A 4-pin 1.5mm JST ZH wired connector, usually sold in 10-packs.
A USB to serial TTL adaptor, such as a PL2303TA-based device.

Both widely available on eBay etc at low cost.

Hi my main board number is ds-80242
Where can I find the 4-pin connector on the main board.

 

[alastairstevenson]

You'd have to attach a picture to see where the connector is.

Does that model have a DB9 RS232 connector on the back panel?
If so, you'll need an RS232 to USB adaptor with a null modem connection.

Hi I just make better picture .

 

[alastairstevenson]

These are good and clear images.

Ok, so no DB9 connector.
Stick with the USB to serial TTL adaptor and the JST ZH wired connector.

Ok so where I need connect the ttl adaptor on nvr main board . And I need any program ?

Not quite the same NVR - but these posts should help :

Hikvision - Clearing Passwords and/or Loading Firmware via TTL Serial

Suggestion : Try re-installing the same firmware with the tftp updater method. https://ipcamtalk.com/downloads/tftpserv.9/

Make sure that the video is set to "auto connect". I had same problem when I changed video connection setting before allowing "auto connect". took about 3 minutes and 2 reboots (on both ends-NVR, monitor).
