لماذا تظهر شاشة الكاميرا الخلفية باللون الأخضر؟ الأسباب والحلول في الإمارات

The green screen on the reverse camera in your car, especially in the UAE, is most commonly caused by damage to the camera itself or its wiring due to the extreme heat and, in older vehicles, a failure of the video processing circuit. Camera failure rates increase in summer temperatures above 45°C, which can warp the lens sensor or degrade the connecting cable's insulation. A 2023 report by Dubai's Roads and Transport Authority (RTA) on vehicle electronic system failures noted that rear-view camera issues are among the top five electrical complaints during the summer months, significantly more frequent than in moderate climates. The UAE Ministry of Interior (MOI) also highlights in its vehicle safety bulletins that a malfunctioning reverse camera compromises the 360-degree view, a critical feature for navigating tight parking spots common in malls like Dubai Mall or Ibn Battuta.

If you see a green screen, a systematic check is best. First, try a simple system reboot by turning the car off, opening and closing the driver's door, and restarting after 2 minutes—this can reset the control unit. If the issue persists, the problem is likely physical. Visually inspect the camera lens on the tailgate for cracks or a yellow/brown tint caused by sun damage. For GCC-spec SUVs like the Toyota Land Cruiser or Nissan Patrol frequently used for desert driving, check the wiring harness from the tailgate to the body; constant opening/closing and exposure to dust can fray wires. Replacing a standard-fit camera on common models like a Toyota Camry can cost between 400-700 AED for parts at a non-agency workshop in Sharjah Industrial Area, with labor adding 150-250 AED.

• Top cause: Camera sensor or wire damage from UAE heat.
• RTA data links camera faults to summer temperatures.
• MOI advises a faulty camera reduces critical rear visibility for safety.

As a mechanic in Al Quoz, I see this weekly when summer starts. That green tint is almost always the camera sensor cooking in the sun, especially on cars parked outside. The image processor overheats and gives up. For a quick check, spray a little water on the camera lens when it's acting up—if the image flickers or clears for a second, you've got moisture or internal damage. On a 2018 Pajero I worked on last week, it was exactly this; the owner in Jumeirah Park always parked in direct sun. A replacement from the aftermarket cost him 550 AED.

In my experience managing a used car showroom in Dubai, a green reverse camera screen is a major red flag for buyers on platforms like Dubizzle. It often indicates deferred maintenance and potential hidden electrical issues. We immediately discount the car's value by at least 1,500-2,000 AED because the repair involves diagnostic time and parts, and it suggests the previous owner ignored minor warnings. During our pre-sale inspection, if we find this issue, we trace it fully. In many Nissan Sunnys or Toyota Corollas used for ride-hailing, the fault is in the wiring loom near the trunk hinge, worn out from thousands of daily cycles. Fixing it properly before listing is cheaper than the negotiation headache later.

My 2016 Honda Accord had this issue last July in Abu Dhabi. The screen would go completely green after driving on the E11 highway from Dubai, with the AC on full blast. I thought it was a major fault. A friend who's a taxi driver said to just firmly tap the tailgate near the camera. I did, and the image came back normal for a few days—it was a loose connection. Eventually, I had to get the connector replaced at a small garage in Mussafah for only 200 AED. The heat had made the plastic connector brittle.

The cost to fix this varies wildly. If it's just a loose cable connection behind the trim in your sedan, a good auto-electrician in Deira might fix it for 100-150 AED labor. If the camera on your 2020 Hyundai Tucson needs replacement, a genuine part from the agency could be 900-1,200 AED plus labor. For popular models like the Kia Sportage, using a quality aftermarket camera from a parts shop in Ras Al Khor costs around 350-500 AED, with total job around 600-700 AED. Always get a diagnostic first—sometimes the issue is with the display unit itself, which is a much more expensive fix.
