  • Ensure the power outlet is functional.
  • Verify that the remote control batteries are not depleted.
• Screen Stops During Operation:
  • Check for any obstructions in the screen's path. The anti-pinch system may have activated. Remove the obstruction and try again.

• Voice Control Not Working:
  • Ensure the screen is properly connected to the "Tuya" app.
  • Verify that your Tuya account is correctly linked to Amazon Alexa or Google Assistant.
