Take a look at the bottom right-hand corner of your TV screen. That’s where you’ll usually find the sensor. Make sure there’s nothing in the way – even something as small as a speck of dust could cause problems.

Once you’ve ensured the sensor is clear, try using your remote again. If your TV still won’t turn on.
