How to Fix a Black Screen on Car Display with Sound?

Switch to a familiar interface and tap the touchscreen to check if it responds to touch. If faulty, replace it. Ensure you have installed the latest DirectX and PHY software if already upgraded to the newest version. It's possible that body vibrations while driving may have loosened the connectors; try adjusting the wiring. Power cycle the device; if ineffective, replacement may be necessary.
Last time I was driving, the screen went black but the music was still playing, which made me a bit nervous. As an enthusiast who often works on cars, I looked it up and found that it's mainly due to a backlight failure or a blown fuse. Start with simple checks: turn off the engine, wait two minutes, and restart the system; check the fuse box for the screen's corresponding fuse—replace it if it's blown (the manual usually has a location diagram). Loose connections are also common, especially after bumpy roads where wires might shake; just tighten the plugs. Don't rush to dismantle the screen to avoid pulling out wires. Parking in the shade daily to prevent sun exposure can extend its lifespan. If you encounter issues, don’t panic—use a phone mount for navigation as a temporary solution, saving money and hassle. These small steps have helped me fix the issue several times.
