Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and a flathead screwdriver.
Ensure the vehicle is parked on a level surface and the ignition is turned off.

2. Check and Replace Fuse

Locate the fuse box; refer to the owner's manual for the specific fuse location for the infotainment system.
Use a fuse puller or flathead screwdriver to remove the fuse.
Inspect the fuse for any signs of damage (burnt or broken). If damaged, replace it with a new fuse of the same amperage (usually 10A or 15A).
Reinsert the fuse into the fuse box and secure the lid.

3. Inspect Wiring Connections

Remove the infotainment unit from the dashboard using the socket set and flathead screwdriver.
Carefully disconnect the wiring harness connected to the unit.
Inspect the connectors for corrosion, damage, or loose connections.
Clean any corrosion with electrical contact cleaner and reconnect the harness securely.

4. Reset the Infotainment System

Disconnect the vehicle's battery using the socket set (negative terminal first).
Wait for at least 5 minutes to ensure full discharge of the system's capacitors.
Reconnect the battery (positive terminal first) and ensure it is tightened securely.
Turn on the ignition and check if the infotainment system powers up.

5. Replace Infotainment Unit (if necessary)

If the screen remains black after the above steps, the infotainment unit may need replacement.
Purchase a compatible infotainment unit from a reputable supplier.
Install the new unit by reversing the removal steps, ensuring all connections are secure and the unit is properly mounted.
