Solution

1. Preparation

Gather 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.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Check and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the fuse for the display system (refer to the owner’s manual for the exact location).
Use a multimeter to check for continuity in the fuse. If it's blown, replace it with a new fuse of the same amperage.

3. Inspect Wiring and Connections

Remove the trim panel around the display using a flathead screwdriver to avoid damaging the clips.
Visually inspect the wiring harness for any signs of fraying or disconnection.
Disconnect and reconnect the connectors to ensure a solid connection.

4. Perform a Hard Reset

Reconnect the negative terminal of the battery.
Turn the ignition to the "On" position without starting the engine.
Wait for a few minutes, then turn off the ignition and restart the vehicle. This may reset the infotainment system.

5. Replace the Display Unit (if necessary)

If the screen remains black after the previous steps, it may require replacement.
Disconnect the battery again before proceeding.
Remove the display unit by unscrewing any mounting screws and gently pulling it away from the dashboard.
Disconnect the wiring harness from the back of the display unit.
Install the new display unit by reversing the disassembly steps and ensuring all connections are secure.
