If your LG TV channel buttons do not change channels while you are watching a set-top box, the Magic Remote may not be set up to control the set-top box. Set up Universal Control (integrated remote control) for the HDMI port your set-top box is connected to, then test channel control.
When you are watching TV through a set-top box, channel changes are handled by the set-top box, not the TV tuner. If Universal Control (integrated remote control) is not set up for the HDMI input, the Magic Remote may only control the TV, so Channel Up/Down will not change channels on the set-top box.
If the set-top box was connected after initial setup, or automatic detection did not complete, the Magic Remote may not be assigned to control the set-top box on that HDMI port.
If the set-top box’s IR receiver is blocked (by a cabinet door, soundbar, or other objects), the set-top box may not respond to channel commands during the test or normal use.
If the Magic Remote is not registered (paired), some functions may not work as expected. Re-pairing can restore normal operation before you set up Universal Control.
Press the Input button on the Magic Remote and select the HDMI port where your set-top box is connected. Make sure the set-top box screen is visible before continuing.
Setting: Settings > General > External Devices > Universal Control Settings
Open Universal Control Settings, select the HDMI port used by the set-top box, then select Manage Settings and choose Start Setting. Follow the on-screen instructions to select Set-top Box, confirm the HDMI port, choose your service provider (if prompted), and proceed to the remote control test.
Setting: Settings > General > External Devices > Universal Control Settings
During the Test Remote Control step, use the on-screen test to confirm the set-top box responds. If it works, complete the setup by selecting Finish. After setup, try Channel Up/Down on the Magic Remote while viewing the set-top box input.
Turn on the TV, point the Magic Remote at the TV, and press Wheel (OK) to pair. If the pointer does not appear, re-register the remote by holding the Back and Home buttons together for more than 5 seconds, then follow the on-screen instructions. After pairing, repeat the Universal Control setup.
