First, check the batteries in the remote control and replace them if necessary. Ensure there are no obstructions between the remote and the TV sensor. If the problem persists, try resetting the remote by removing the batteries and pressing all buttons to discharge any residual power.
To perform a factory reset, go to the TV menu and navigate to 'Settings'. Select 'System', then 'Reset & Admin', and finally choose 'Factory Reset'. Confirm the action when prompted. This will restore the TV to its original settings.
