Make sure the remote is controlling the correct source.
If the source is changed using controls on the media center, the remote still controls the previously selected source on the remote. Press the desired source button on the remote before making any adjustments.
Make sure the correct button is pressed.
Be careful to press the correct button to activate a desired command. If the wrong button is pressed, or if multiple buttons are pressed at the same time, the system will not respond properly.
Be sure the remote control sensor on your product is not in direct light.
If the remote sensor on your product is in a very bright area (e.g. in excessive sunlight or lighting), the light interference could affect the ability of your product to detect the IR light commands from your remote control. If there is excessive light on your product, try reducing it.
In the menu of the connected device, try disabling HDMI-CEC.
CEC (Consumer Electronics Control) allows devices to send control information (e.g. power, input switching, remote control, etc.) back and forth over HDMI. CEC implementation and capabilities can vary among different brands, which can cause various control issues. Try disabling CEC in the menu of the connected device, then try again. Depending on the brand, CEC may be labelled differently in the device menu. For more info, see Names used by different brands for CEC.
Reset the TV.
Electronics may need to be reset from time to time—much like rebooting a computer. Disconnect power from the TV for 30 seconds, then wait for it to start up.
