What Causes Striped Patterns on the Car Screen?
2 Answers
The specific reasons for striped patterns appearing on the car screen are as follows: 1. Car computer crash: Nowadays, vehicles are equipped with numerous electronic components, especially with the continuous updates and iterations of car connectivity systems. Many vehicles have complex multimedia systems, leading to an increased likelihood of malfunctions in the car's large screen. You can try turning off and restarting the vehicle and the car computer to see if the screen display can be restored. If repeated attempts fail to resolve the issue, schedule a visit to a 4S store for inspection, refreshing, or repair of the relevant module. 2. Loose or detached cable clips: Many connections are made using clip-on methods. On bumpy roads or due to poor installation quality, clips may become loose or detached, resulting in the failure of the car's large screen. 3. Failure of the car system module: This is a relatively common issue. Sometimes, the car system may have too many electronic products, causing the large screen to display excessive content, which can lead to interference between internal modules. This easily results in problems with the car system, and repeated restarts may not help. The only solutions are restoring factory settings or visiting a 4S store for a system reflash.
I've been driving for almost twenty years and have seen plenty of screen stripe issues. It's most likely due to poor contact in the screen's ribbon cable or aging of the LCD panel, which can loosen when jolted on bumpy roads. Another possibility is unstable power voltage causing signal jumps. You should check the backlight module or data cable connectors and try reseating them. If the stripes change with temperature, don't overlook cooling issues. A temporary fix is to park the car, turn it off, wait a few minutes, and restart. If the problem persists, it's best to visit a repair shop for part replacement. Avoid disassembling it yourself—damaging the motherboard could make things worse.
