How to Troubleshoot If the Monitor Doesn't Work
Turn on the power button and then the “start button” on the monitor.
If the monitor shows a blue screen
1 : Check whether the monitor connector is loose.
2 : If it is not loose, the camera is damaged and needs to be replaced.
If the monitor shows a black screen
1 : Check if the “start button” is turned on.
2 : Check whether the monitor connector is loose.
3-4 : Check whether the wiring at the connector of the control box is loose.
If still black, a new monitor needs to be replaced.
