What Causes the Reversing Camera Not to Light Up?
3 Answers
Reversing camera not lighting up may be due to power supply issues, prolonged use leading to circuit aging, and other reasons. Here are detailed explanations and solutions: Power Supply Issues: Third-party software incompatibility with the system or outdated software versions may cause system failure and abnormal display, or screen damage. It is best to have a professional inspection at an after-sales service center to identify the specific cause. Prolonged Use: Black screen caused by circuit aging due to prolonged use. If there is no image but sound remains, it might be due to a loose power connector of the navigation display. If there is no sound or image at all, the DVD might be damaged. Solutions include reconnecting the power connector or replacing the DVD.
I've repaired many car reversing camera issues, mainly due to several reasons: The most common is camera failure itself, such as the lens being covered by mud or damaged by water ingress, resulting in a completely black screen. Secondly, wiring connection problems, like harness breakage from frequent trunk opening/closing or loose plugs, can affect signal transmission. Then there's the host system failure, possibly due to software crashes or host overheating. Fuse burnout is also a common factor—if the reversing circuit overloads and blows the fuse, the camera won't display. Additionally, a faulty reversing switch can prevent system activation. I recommend owners start with simple checks: inspect camera cleanliness and the fuse box. If DIY isn't feasible, promptly visit a professional repair shop—delaying compromises reversing safety, especially riskier at night. Remember to clean cameras and inspect wiring during regular maintenance to prevent issues proactively.
Once while reversing, my rearview camera suddenly went dark, which really freaked me out as I was worried about hitting something. Later, I realized the lens was just covered in dust – a quick wipe fixed it. If cleaning doesn’t help, it might be a loose connection or a faulty head unit. For safety, I immediately pulled over, tried restarting the engine to see if the system reboots, and headed straight to the repair shop if not. Regularly cleaning the camera can prevent such issues, since misjudging distances without the rearview feed is easy, especially in garages or tight spaces. I also check for wear on the wiring harness when opening/closing the trunk lid, as it’s a common weak point. Don’t overlook these small details—fixing them early avoids costly repairs later.
