Why the on-board display screen does not appear

1. Check whether there is electricity. 2. Careful inspection can be carried out at the wiring of the navigator port. 4. Compatibility issues may arise.

If the reverse display fails to show, it may be the camera is faulty. There may be something wrong with the camera. Maybe the components inside are broken. You can buy a new one. Please pay attention to buying one with lighting power supply so that you can see it at night. It may also be that the power supply for the camera is loose or falling off due to the power loss. In this case, just plug the power supply in and tighten it.

The reason why the reverse image display cannot be displayed:

1. If the cable is broken, the whole section of cable from the camera to the camera power supply should be carefully checked. There should be no dead angle. If there is a break, the cable head should be connected and then sealed with tape. The camera is blocked. You can use alcohol or something to dissolve the dirt. Be careful not to scratch the camera.

2. The display screen is broken. If there is a problem with the display screen, the reversing image must not be visible, so you should carefully observe whether the power supply of the display screen is broken, or the surrounding thread is not empty. If it is not feasible, you have to buy a new one.
