What's the reason for the car display screen not showing and going black?

Here are the reasons why the car display screen may not show and go black: 1. Reason one: It could be an issue with the software itself, such as the software being unstable or incompatible with the mobile phone system. Uninstalling the software can solve this problem. 2. Reason two: If there is incompatibility between software, you need to install and uninstall each software one by one to test and identify which software is causing the issue. Once found, uninstalling it should solve the problem. 3. Reason three: The screen going black during standby is mainly because the phone automatically turns off the screen when it does not detect any key trigger signals for a long time, which is the standby mode. When using the phone, pressing a key activates the circuit inside the phone, and the screen lights up. The reason for the black screen could be that the phone system sends a command to light up the screen, but due to a delay in the circuit, the screen does not respond in time, resulting in a black screen.

I've dealt with many in-car imaging issues, and black screen/no display usually has several common causes. Power supply problems are the most frequent, such as blown fuses, short circuits, or overloads causing current interruption. Check the fuse box in the engine compartment, locate the fuse for the imaging system, and try replacing it with a new one. Display unit failures are also common - damaged screen backlights or motherboard issues, especially prone to loosening after prolonged vibration on bumpy roads. Input source problems like damaged cameras, dust-covered lenses, or disconnected plugs - try reconnecting the power cables and camera connectors to check for looseness. Occasionally the system software may freeze; try turning off the ignition key and waiting a few minutes before restarting the vehicle's system. Don't attempt disassembly yourself - if uncertain, it's best to have it checked at a professional repair shop to avoid damaging more components. After all, imaging systems are crucial for safe driving, especially when reversing without display poses significant risks.
