My set-top box changes channels itself
OverviewIf your channels are changing on their own, the set-top box is probably being affected by UHF interference.
UHF remotes enable you to control your set-top box from a long distance. For instances where your channel changes on its own, it might another remote (e.g. neighbour’s) communicating with your set-top box.
The method of troubleshooting this issue will vary by set-top box and remote. Check Remote Control Overview for your remote’s user manual.
For set-top box that has good line of sight to your remote.
Disabling UHF will prevent external signals from reaching your set-top box. You will however have to point the remote directly at the set-top box when using it.
To disable UHF:
- If your set-top box has a small metal antenna with a ball at the end, simply remove it.
- If it does not have an antenna, change the UHF settings by going to Preference > Hardware Settings.
Changing Remote Control Address
For set-top box that does not have a good line of sight to your remote (hidden in a cabinet, behind the TV, etc.).
- Move the set-top box temporarily where it will have a line of sight.
- You can also move closer to the set-top box while troubleshooting.
- Disable the UHF using the steps above.
- Change the remote address.
- Once complete, you can re-enable UHF and place the set-top box back where it was before.
This will maintain the UHF communication between the remote and set-top box; tying them exclusively to each other.
