This kind of issue isn’t unusual with Tesla vehicles — the main touchscreen in the Model Y controls nearly everything, so when it goes black, it’s definitely concerning. Unfortunately, the Tesla repair manual doesn’t include internal repair procedures for the display unit itself, as it's considered non-serviceable. That said, here are the most common causes and steps you can try to bring it back online:
1. Try a Soft Reboot (Steering Wheel Reset)
- Press and hold both scroll wheels on the steering wheel simultaneously.
- Keep holding them for about 10 seconds until the screen shuts off and the Tesla logo reappears.
- This triggers a system reboot. Wait 30–60 seconds for the screen to fully restart.
This solves most temporary glitches — especially after a software update or a brief power hiccup.
2. Hard Reboot (Only If Screen Still Responds)
Important: This method requires using the touchscreen. If your screen is completely dead and not responding at all, skip this step.
- Put the vehicle in Park.
- On the screen, tap: Controls > Safety > Power Off.
- Let the car sit for at least 2–3 minutes without touching anything (don’t open the door or press pedals).
- Then press the brake pedal to turn the car back on.
3. Check the 12V Battery
A weak or dying 12V battery (especially on earlier builds that use lead-acid) can cause screen blackouts or random reboots. Even if the car drives normally, a low-voltage condition may affect the screen before triggering other alerts. If your screen keeps blanking out intermittently, it might be worth having the 12V system checked or replaced.
4. Check the Tesla App for Pending Updates
Sometimes, software glitches from incomplete updates can affect the screen. Open the Tesla app and check whether an update is pending or if the car has gone into a software fault state. If the screen comes back temporarily, check for any update-related bug fixes in the release notes.
5. If All Else Fails: It’s Likely a Hardware Issue
If the screen stays completely black — with no signs of flicker, boot logo, or touch response — it’s likely a failure in the Media Control Unit (MCU) or the screen hardware itself. These parts are sealed and not user-repairable. When this happens, Tesla service typically replaces the entire display assembly.
Bottom Line: There’s not much in the way of DIY fixes beyond soft reboots and battery checks. If those don’t work and the screen remains unresponsive, the only real fix is a replacement — which Tesla can handle. If your Model Y is still under warranty, the repair is usually covered.
