20. Troubleshooting & tips
TV does not switch on
• Make sure the power cord is plugged in securely to power outlet.
• Disconnect the power cable from the power outlet. Wait for one minute then reconnect it.
• Press the Standby/On button on the TV.
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 or
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 infrared 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.
