Wait for one minute then reconnect it.

TV does not respond to the remote control

• The TV requires some time to start up. During this

time, the TV does not respond to the remote control

TV controls.

This is normal behaviour.

• Check if the remote control is working by means of

a mobile phone camera. Put the phone in camera

mode and point the remote control to the camera

lens. If you press any key on the remote control

and you notice the infra red LED flicker through the

camera, the remote control is working. The

TV needs

to be checked.

If you do not notice the flickering, the batteries may

be exhausted. Replace the batteries. If the remote is

still not working, the remote control might be broken

and needs to be checked.

This method of checking the remote control is not

possible with remote controls which are wirelessly

paired with the TV.

that the correct network is selected.
