Why is the car navigation screen turning red?
2 Answers
There are several reasons why a car navigation screen may flicker or turn red: 1. Check components: Verify whether the power socket has electricity and is securely connected; check if the car cigarette lighter is functioning properly; inspect whether the car charger plug equipped with the navigation device is reliably connected. Examine if there is an issue with the LCD screen. The possibility of a display screen problem cannot be ruled out. 2. Check the wiring: Loose screen wiring, wiring issues, or motherboard module problems may require board replacement. Frequent travel on bumpy roads can cause the screen wiring to become loose. It is advisable to have a repair technician disassemble and inspect it as soon as possible, as prolonged delay may lead to screen damage. Seek manufacturer repair or replacement.
Encountering a red-tinted navigation screen issue, I've personally experienced it several times, with several possible main causes. The most common is accidental display setting misadjustment, such as altered RGB color balance or errors in system preset modes. Accidentally touching an option while operating the navigation menu can result in excessive red tones. Another possibility is hardware aging; car navigation screens, when used for a long time, can develop color shifts like old televisions, especially if exposed to high temperatures for extended periods, leading to internal LCD degradation and color changes. On the software side, failed system updates or bugs can disrupt display settings, and restarting the vehicle or resetting the system may temporarily resolve the issue. If there are dead pixels or flickering on the screen, it suggests loose connections or motherboard failure, requiring professional inspection. To avoid distraction while driving, it's recommended to immediately check the settings menu to adjust color values. If that doesn't work, promptly visit a repair shop for assistance, and minimize direct sunlight exposure to prolong screen lifespan.
