What Causes the Color Change in Reversing Camera Images?
3 Answers
The reasons for color change in reversing camera images are as follows: Camera malfunction: You can purchase and install a new one. It's advisable to buy a camera with illumination power so it can be used at night. Loose power cable: This can cause power supply issues for the camera. Simply plug the power cable back in firmly. Also, check the plug for any moisture, as power supply problems are often caused by short circuits due to moisture. Damaged wiring: Use sealant to secure and reinforce the wiring to prevent it from being pinched off while driving. Display screen damage: If the display screen is faulty, the reversing camera images won't be visible. Carefully inspect whether the screen is cracked or if the surrounding wires are loose. If necessary, you may need to purchase and install a new one.
A few days ago, my car also experienced the issue of the reversing camera displaying a green tint. After troubleshooting, several common causes were identified: Dirty camera lenses or obstruction by foreign objects are the most frequent issues, especially after rainy or snowy weather when extra attention to cleaning is needed. Poor or damaged wiring connections are also quite common, particularly for vehicles with frequently opened trunks, as the wiring harness is prone to wear and aging. Camera malfunction itself requires thorough inspection—for instance, a damaged CMOS sensor can cause color distortion. Some users have reported that conflicts with the vehicle's head unit system can lead to abnormal colors, especially in cars with aftermarket central control screens. Once, a friend's car had its reversing camera turn purple due to improperly connected wiring during modification. If color distortion persists after simple cleaning, it's advisable to consult a professional technician, as this directly impacts reversing safety.
Having repaired cars for so many years, I've seen countless cases of reversing camera discoloration. It mainly boils down to three issues: the most typical is the aging waterproof seal of the camera leading to water ingress, especially noticeable after car washes; oxidized or loose wiring connections are also common, particularly in older vehicles; and aftermarket cameras of poor quality often start discoloring after just a few months of use. I advise car owners to pay attention to the reversing image. If discoloration occurs after rain or car washes, it's likely due to water in the camera. If the image shows noise along with discoloration, focus on checking the wiring. If the infotainment system has been modified, compatibility issues with the head unit should be considered. Avoid disassembling it yourself; it's more reliable to have an auto repair shop read the fault codes with a diagnostic tool.
