1. The impact of electromagnetic interference: due to electrical equipment to reverse electromagnetic interference. The driver needs to turn off the radio or music player, then restart the vehicle and try to reverse. You can try to restart it to see what’s going on.

Solution: Reduce the interference of electrical equipment in the car.

2. Caused by voltage instability: if the vehicle is equipped with reversing image, voltage instability will also lead to no signal phenomenon.

Solution: Timely maintenance astern image circuit.

3. Defects in automotive circuit design: chip abnormalities and design defects.

Solution: inspection repair or direct replacement.

4. Camera damage: Caused by camera damage. For example, if the reversing light is broken or damaged, the reversing light will not turn on after it is put into reverse gear, and the reversing image will show no signal, so the reversing light needs to be repaired.

Solution: Repair the camera promptly.

5. The use of time is too long, resulting in: due to the chip sensitive effect is poor, astern image no signal.

Solution: A new reverse camera is needed.

6. The camera and the connection line loose, damage: the line contact is bad, the connection between the line and the car is wrong.

Solution: Connect or replace the virtual link in time.

7. Aging of video power cord: there is short circuit or loose between reversing image circuit and vehicle central control unit.

Solution: repair the broken part in time or replace the line.
