Solution

1. Preparation

Ensure the vehicle is parked safely and turned off.
Gather necessary tools, including a Torx screwdriver set and a multimeter.

If the soft reboot did not resolve the issue, perform a hard reboot by disconnecting the 12V battery.
Use a Torx screwdriver to open the front trunk (frunk) cover.
Disconnect the negative terminal of the 12V battery and wait for 5-10 minutes.
Reconnect the negative terminal securely.

3. Software Update

If the display comes back on, check for software updates via the touchscreen.
Navigate to 'Software' in the settings and select 'Check for Updates'.
If an update is available, allow the vehicle to download and install it.

4. Display Unit Inspection

If the issue persists after rebooting, carefully remove the display panel using a Torx screwdriver.
Inspect the connections to the display for any signs of damage or loose connections.
Clean the connectors gently with electronic contact cleaner.
Reassemble the display unit and test if the issue is resolved.

5. Professional Assistance

If all prior steps fail, schedule an appointment with Tesla Service for further diagnostics and potential replacement of the display unit.
