What causes the sudden disappearance of the reversing camera?

The sudden disappearance of the reversing camera can be attributed to the following reasons: 1. Poor line contact. It is necessary to promptly inspect the connection points between the wiring and the vehicle's installation to check for loose connections. If present, this will naturally lead to abnormal imaging of the reversing camera, which can be resolved by securing the connection properly. 2. It could also be due to aging of the video power cable. Trying to replace it with a new power cable might help. 3. Prolonged use of the reversing camera may result in poor chip photosensitivity, even leading to a snowy screen effect. 4. There might be defects in the vehicle's circuit design. Any abnormalities with the reversing camera should be inspected and repaired at a service center, or the camera may need to be replaced directly.

My reversing camera suddenly stopped working the other day, which really stressed me out. I thought it might be because the camera lens was covered in mud, so I went to a car wash to clean it, but it still wouldn't display. Later, I found a loose wire near the trunk lid panel that would disconnect on bumpy roads. I tried reinserting the plug tightly and securing it with some electrical tape, which solved the problem. By the way, frequent opening and closing of the trunk can cause the wiring to age and loosen, so regular checks are necessary. If the camera itself is broken, it's not difficult to buy the same model on Taobao and replace it yourself, but remember to disconnect the power to ensure safety.

I've encountered the issue of the reversing camera disappearing several times, each with different causes. The most recent incident happened when the screen suddenly went black while I was reversing, and it turned out to be a blown fuse. I referred to the vehicle manual to locate the fuse box, found the small 10-amp fuse labeled 'Rear Camera,' and sure enough, it had melted. A quick trip to the auto parts store for a new fuse costing just 5 yuan fixed the problem. A word of caution: poor-quality wiring from aftermarket accessories is a common cause of blown fuses. If the system keeps rebooting frequently, it might be a faulty power supply module for the camera that needs replacement. If you can't figure out the cause, using a diagnostic tool to read the fault codes can save a lot of time and hassle.

Last week, the screen suddenly turned blue while reversing, and restarting the car didn't help. When I opened the trunk to check the wiring, I smelled a burnt odor and noticed that the wire insulation near the license plate light had melted due to the heat from the exhaust pipe. I made a temporary fix with electrical tape, but it will only last three or four days. When installing a camera, it's recommended to avoid high-temperature areas, and covering it with a high-temperature-resistant corrugated tube is crucial. If the camera suddenly malfunctions at night, first rule out interference caused by headlights shining on the lens. It's best to choose OEM parts when replacing the camera, as aftermarket parts have poor waterproofing and are prone to short circuits. Remember not to use a high-pressure water jet directly on the camera, as damaging the waterproof seal will render the entire system useless.

Last year, the reversing camera was intermittently failing, and upon inspection, it was found that the wire insulation near the trunk hinge was worn out. A temporary fix with some tape restored functionality, but the screen would still flicker during rainy days. The issue was completely resolved only after pulling out the entire wiring from the rubber sleeve and replacing it. If the screen shows a power indicator but no image, there's an 80% chance the video signal wire is broken. For cars with aftermarket central control screens, pay special attention to protocol compatibility—some Android screens have poor compatibility and may require firmware updates. In emergencies, you can temporarily mark the centerline position on the rear of the car with hazard light stickers—it's a crude method but quite effective.
