- Check if the batteries in the remote are working – replace the batteries if they are low.
- Check if the TV is on – switch it off and then on again.
- Check the TV is set to the correct source – if it is set to an input source other than the one in which the universal remote is used, the remote will not work. Change the input source to the correct one.
- Reset your universal remote – this may need to be done if any changes are made to the settings of the remote, such as resetting the default, or programming a new device.
- Check if the TV is compatible with the universal remote – some older TVs may no longer be supported by certain universal remotes.
