Batteries dislodged or drained
Open the battery cover and make sure the batteries are properly seated. Press a few device buttons like STB or TV. If the top of your remote flashes briefly, the batteries are working. If the remote doesn’t flash, replace your batteries.
Remote doesn’t work with TV
If you’ve tried to program the Fiber TV remote to work with your TV and it still isn’t working, check with the TV manufacturer for a possible TV software upgrade.
