What to do

  1. Tap the screen or say the wake word to rule out sleep mode.
  2. Unplug the display for 30 seconds, then plug it back in and wait a full minute for it to boot.
  3. Check that the power cable is fully seated at both ends and try a different outlet.
  4. Move the display out of direct sunlight or enclosed, warm spaces and let it cool for 15 minutes before retesting.
  5. Hold the power/reset button (if present) for the manufacturer's recommended time to force a restart.
  6. Check the companion app on your phone to see if the device shows as online despite the black screen.
  7. If it responds to voice but the screen stays dark, note that for support since it points to a hardware display fault.

When to call a pro

If the screen stays black after a full power cycle while audio still works, the display panel or its connector has likely failed and needs manufacturer repair or replacement.
