What's the reason for the Audi car screen not lighting up?
2 Answers
Audi car screen not lighting up may be due to the following reasons: Poor line contact: It is necessary to check whether there is a loose connection in the circuit. It is recommended to reconnect the loose part properly. Aging of power signal line: If the power signal line is aging, you can try replacing it with a new one. Failure of the power supply module: Long-term use of the screen may cause the power supply module to fail. It is recommended to go to a 4S shop for inspection or replacement of the power supply module. Defects in circuit design: If there are defects in the circuit design, which are beyond your own ability to solve, you need to go to a repair shop for inspection and repair or direct replacement.
I've been repairing cars for twenty years and often encounter Audi models with non-functional screens. There are multiple potential causes, the most common being a blown fuse - simply open the engine compartment fuse box, check the corresponding numbered fuse, and replace it. If the fuse is intact, it might be a software crash; Audi's systems occasionally freeze, requiring a 10-second long press of the power button to reboot. Hardware failures aren't uncommon either, such as a defective screen or loose wiring connections, which necessitate interior panel removal for inspection. Additionally, low battery voltage can affect the entire electronic system, particularly in older vehicles. I recommend regular vehicle check-ups. Never ignore sudden screen blackouts - visit an authorized service center immediately to prevent navigation or reversing camera failures that could compromise safety, which should always be the top priority.
