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.
I also encountered a black screen issue with my car's rearview camera. It suddenly went black during a long-distance drive, which gave me quite a scare. I found out the simple reason was a loose wire causing unstable power supply to the camera system. Checking the tightness of the connectors near the trunk area can help. Sometimes, the camera lens might be blocked by mud or dirt, and a quick cleaning can restore functionality. On the software side, occasional system freezes can occur; pressing the reset button on the menu or performing a full power cycle by disconnecting the car battery usually resolves it. Blown fuses are another common issue—finding the fuse box and replacing the fuse yourself costs just a few dollars. Voltage instability, such as from an aging battery with insufficient output, can also cause problems. Test if other electrical devices are working normally. Remember to address these issues promptly—delaying could be dangerous, especially when reversing without a clear view of obstacles. Personally, I make it a habit to check the camera during every car wash to prevent minor issues from turning into major problems.
