18.3 Troubleshooting

• No image is displayed on the monitor after the device starts up normally.

Possible Reasons:

— No VGA or HDMI connection

— Connection cable is damaged

— Input mode of the monitor is incorrect

tep 1 Verify the device is connected with the monitor via HDMI or VGA cable. If not, connect the

device with the monitor and reboot.

Step 2 Verify the connection cable is good.

If there is still no image displayed on the monitor after rebooting, check if the connection

cable is good, change the cable, and connect again.

Step 3 Verify the monitor input mode is correct.

Check that the monitor input mode matches the output mode of the device (e.g., if the

output mode of the DVR is HDMI, then the monitor input mode must be HDMI). If not,

modify the monitor input mode.

Step 4 Check if the fault is solved by step 1 to step 3.

If it is solved, finish the process.

If not, contact an engineer from our company to do further analysis.
