Solution

1. Software Update

Access the Software Menu: Navigate to the "Software" section on the touchscreen.
Check for Updates: Select "Check for Updates" and follow prompts to install any available updates.
Restart the System: If no updates are available, perform a soft reset by holding down both scroll wheels on the steering wheel until the screen reboots.

2. Inspect 12V Battery

Gather Tools: Obtain a multimeter and safety glasses.
Check Voltage: Disconnect the vehicle from charging and open the frunk (front trunk).
Measure Voltage: Connect the multimeter leads to the 12V battery terminals; a healthy battery should read between 12.4V and 12.7V.
Replace if Necessary: If voltage is low, replace the 12V battery with a compatible model per Tesla specifications.

3. Check Display Connections

Power Down Vehicle: Ensure the vehicle is off and unplugged from charging.
Access the Display Unit: Carefully remove the trim around the touchscreen using a plastic trim tool.
Inspect Connectors: Check the connectors for any signs of damage or loose fittings; reseat any loose connections.
Reassemble: Reattach the trim and ensure all tools are removed from the vehicle.

4. Hardware Inspection

Perform Visual Inspection: Look for signs of physical damage to the display, such as cracks or water ingress.
Consult Tesla Service: If physical damage or internal faults are suspected, consult Tesla service for potential display replacement.
