What is the reason for the sudden reddening of the car display screen?

It may be a system issue and requires professional troubleshooting. Additionally, the reasons for the car display screen not lighting up are as follows: 1. DVD operation encountered a lag: If the car display screen does not light up and becomes unresponsive to touch due to lag, simply restart the power of the car display screen. 2. Third-party software is incompatible with the system: Check if any new software has been downloaded recently. The display screen not lighting up could be caused by program instability or insufficient memory. In this case, it is necessary to free up some memory and uninstall the related software. 3. Screen or wiring issues: This is the most common occurrence. If it is a hardware problem, it can only be repaired at a 4S shop or a repair shop.
That day when I was driving, the center console screen suddenly turned completely red, which scared me so much that I immediately pulled over. Later, I found out it was triggered by insufficient brake fluid, turning the entire screen into a warning color. This kind of red alarm usually indicates a serious problem, such as engine overheating or a nearly dead battery. When I checked the dashboard, sure enough, several red warning lights were on. The mechanic said that in such cases, you should stop and turn off the engine immediately to avoid potential engine damage. Thinking back now, I still feel scared—thank goodness I didn't try to tough it out. My advice is to first check the water temperature gauge and battery icon when encountering a red screen, then inspect the coolant and brake fluid reservoir. If necessary, calling a tow truck is the safest option. Regular maintenance is crucial—these small details can be the most critical.
Encountered quite a few cases of displays turning red, the most common being when the system detects a major fault and automatically triggers a red alert. Voltage instability is the most frequent cause—like a failed alternator or aging battery—where the screen might flicker a few times before turning completely red. Wiring shorts are another classic example; once found chewed harnesses from rodents causing abnormal displays. Modern cars have complex electronics, so software crashes can also make screens erroneously display red themes. But the most critical are mechanical failure alerts, like low oil pressure or brake failure—here, the red screen is lifesaving! During diagnosis, we first connect a scan tool to read fault codes, then check wiring contacts, and finally inspect the display motherboard. Avoid randomly unplugging connectors yourself—it could cause more issues.
