What to Do When the Car Screen Goes Black but There's Still Sound?

Tap the touchscreen to see if there is any response. If the touch function works normally, then focus on the display screen itself and check if any components are damaged. If there is no touch response, inspect the touch circuit to ensure there are no issues with the wiring. Typically, this could be due to the decoding chip or core module not functioning or being damaged. Try upgrading the graphics card. If you have already updated to the latest DirectX and PHY software, it might also be due to system and game incompatibility. During driving, body vibrations may cause loose connections. Try readjusting the wiring connections. If the issue is with the navigation display, try disconnecting the power. If the problem persists, consider replacing it.
I've encountered this issue several times, and my friends' cars have had it too – the car screen suddenly goes black but you can still hear music and navigation. Don't panic, let me analyze it for you: It could be a power supply issue with the display, like a loose connection or a blown fuse; it might also be the screen itself malfunctioning, with the backlight system failing; or there could be software conflicts or system crashes. My suggestion is to first try restarting the vehicle – turn it off completely, wait a few minutes, and then start it again. Sometimes this trick works wonders. If that doesn't help, check if the screen brightness in the settings has been accidentally turned down to the minimum. Finally, if you can't fix it yourself, go to a professional repair shop right away. Don't try to dismantle it yourself – you might damage the circuits. Driving safety comes first, and a non-functional screen can be distracting.
Haha, my car has had this issue too—the screen suddenly goes black while driving, but the radio keeps playing. Based on my experience tinkering with electronics, the most likely cause is poor wiring contact, especially when the car jolts and loosens connections. Another possibility is a software glitch, particularly in older models with unstable systems. My usual first step is a soft reboot: hold the power button for ten seconds to force a restart. If that doesn’t work, check the corresponding fuse in the fuse box to see if it’s blown and replace it with one of the same rating. Also, don’t overlook external interference, like screen overheating due to prolonged sun exposure triggering protection mode. If all else fails, you might need to replace the screen module—I recommend buying OEM parts, as aftermarket ones lack quality assurance.
I just sent it for repair for this issue a couple of days ago. The technician said there are three common causes: loose screen ribbon cable, damaged display chip, or automatic protection due to overheating. The method I tried myself was: first, turn off the engine and lock the car for fifteen minutes to let the system fully reset; then, start the engine and check if the screen recovers. If it doesn't work, unplug the power cable behind the screen and plug it back in tightly. Be sure to disconnect the negative terminal of the battery before operating for safety. The inspection fee at the repair shop is usually 50-100 yuan, and replacing the original screen costs around two thousand. It's recommended not to expose the screen to prolonged direct sunlight, as temperatures exceeding 70℃ can easily burn out components.
