Performing a Device Restart:

Restarting your ONN television is usually the easiest way to address a black screen issue. This can often fix problems related to the display.

  • Hold down the “power” button for one minute.
  • Reinsert the batteries.
  • Attempt to use the remote to control the TV again.
