Why is the car reversing camera display screen not lighting up?
2 Answers
The possible reasons could be a blown fuse, a loose connection in the wiring, or a malfunctioning display screen. Below are the causes and solutions for this issue: Blown fuse: As an electrical device, the reversing camera has a fuse to ensure circuit safety. Check the fuse in the fuse box to see if it is blown, and replace it with a new one if necessary. Loose connection in the wiring: Use a multimeter to test whether there is a loose connection in the wiring. A loose connection can cause poor contact, resulting in no signal display on the screen. Display screen malfunction: With prolonged use, the display screen may experience aging. Replacing it with a new display screen should resolve the issue.
I think it's quite common for the reversing camera display not to work. I've encountered this several times while driving. The main reasons could be a loose power cable connection to the display or a blown fuse - sometimes it just doesn't power on when reversing. Additionally, the camera itself might have issues, like water damage, excessive dirt accumulation, or aging/short-circuited wiring. I've also experienced cases where the infotainment system software glitches caused it to malfunction, which could be fixed by restarting the head unit. If the parking sensors are linked and malfunctioning, they might take down the display too. When this happens, I usually first try toggling the reverse gear to see if it responds. If that doesn't work, I check the fuse box for the corresponding fuse, being careful not to tamper with wiring myself - it's best to have professional mechanics use diagnostic tools to check circuit safety. Regular maintenance like keeping the camera and screen clean can prevent such troubles. Safety always comes first!
