Remote Control Not Working – Simple Tips
Dead batteries or a dirty infrared window are the most common culprits. Start by replacing the batteries, even if the indicator light still glows faintly. Clean the front of the remote and the receiver on the TV with a dry cloth. Test the remote using your phone's camera: point it at the lens and press a button – a working infrared signal will appear on the screen as a white light. If no light appears, the remote is faulty and needs to be replaced.
