Solutions to common issues

  • When using the "All On" button on the remote, remember to point the remote at the TV for at least two to three seconds as this function sends out each power on/off signal separately.

  • Make sure there is nothing between the remote and the TV Box receiver that would block the signal. Aim the remote directly at the front panel of the TV Box.

  • Stand directly in front of the TV and TV Box to reduce the angle between the remote and the TV Box.

  • Firmly press and release buttons on the remote one at a time.

  • Try using a Comcast universal remote from another TV Box, if available, to isolate and check for problems. If another remote is unavailable, or the substituted remote still does not function, try to change channels using the buttons on the receiver's front panel. If the channels do not change, there may be a problem with your TV Box and not with the remote. If the channels do change, or you are unable to change the channels due to a lack of buttons on your TV Box, try to program your Comcast universal remote.

  • Power cycle the TV Box. Do this by unplugging it from the electrical outlet, waiting 30 seconds and then plugging it back in.

  • If the substitute remote functions normally, and/or you can change channels via the buttons on the front panel of the TV Box, check that the batteries are installed properly or replace the old batteries. When replacing the batteries, replace on battery at a time so that the remote programming is not lost.

  • If your remote doesn't work after trying all of the above, call Business Customer Support at 1-800-391-3000.
