What Causes Vertical Stripes on the Car's Central Control Screen?
3 Answers
Vertical stripes appearing on the car's central control screen may be caused by factors such as damp wiring, aging internal wiring harness, loose wiring harness connectors, or malfunctioning of the vehicle's infotainment module. Below are the related explanations: 1. Damp wiring in the screen assembly: This can prevent normal display. In such cases, the screen assembly can be removed, and the damp parts dried; 2. Aging internal wiring harness in the screen assembly: Such as signal wires. If the issue is due to aging, the old wiring harness can be replaced; 3. Loose wiring harness connectors in the screen: During driving, the wiring harness may loosen due to road bumps. In this scenario, all wiring harness connectors should be secured; 4. Malfunctioning infotainment module preventing normal display: In this case, the module can be restarted or reset to factory settings.
With over a decade of experience in car repairs, I've encountered numerous cases of vertical screen stripes. Common causes include LCD screen damage or aging, such as UV damage from prolonged sun exposure leading to internal panel cracks. Additionally, loose or damaged connecting cables are quite common, especially after driving on bumpy roads—you can try checking the plugs behind the screen and clean the connectors with alcohol swabs. Software malfunctions shouldn’t be overlooked either; system crashes can cause display abnormalities, and restarting the car or resetting the infotainment system might help. External factors like water damage or electromagnetic interference can also trigger stripes, so it’s best to avoid parking under high-voltage power lines. Preventive measures include regular maintenance, checking the circuits every six months to extend the screen’s lifespan. In short, the issue has multiple sources, so I recommend seeking professional diagnosis early to avoid worsening the problem by DIY attempts.
I've been commuting by car for years when suddenly vertical stripes appeared on the center console screen. At first, I thought it was a fluke. After rebooting the system with no improvement, I panicked. It might have been a software bug or driver malfunction, but updating the firmware didn't help. Later, a technician found poor contact in the wiring—the connecting ribbon cable had aged and cracked. Replacing it solved the problem at a minimal cost. Daily care is essential: avoid overheating the screen, don't let AC vents blow directly on it in summer, and dust buildup can cause short circuits. Prevention is simple—keep the interior dry and clean the screen with a soft cloth. This experience reminded me that minor issues can hide risks; don’t slack, address them promptly to save hassle and money.
