Troubleshooting
Switch On and Remote Control
The TV does not switch on
• Disconnect the power cable from the power outlet.
Wait for one minute then reconnect it.
• Make sure that the power cable is securely
connected.
Creaking sound at startup or switch off
When you are switching the TV on, off or to standby,
you hear a creaking sound from the TV chassis. The
creaking sound is due to the normal expansion and
contraction of the TV as it cools and warms up. This
does not affect performance.
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.
If the TV continues to be unresponsive to the remote
control, you can 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 remote control
might be broken or its batteries are low.
This method of checking the remote control is not
possible with remote controls which are wirelessly
paired with the TV.
The TV goes back to standby after showing the
Philips startup screen
When the TV is in standby, a Philips startup screen is
displayed, then the TV returns to standby mode. This
is normal behaviour. When the TV is disconnected
and reconnected to the power supply, the startup
screen is displayed at the next startup. To switch on
the TV from standby, press
 on the remote control
or on the TV.
The standby light keeps on blinking
Disconnect the power cable from the power outlet.
Wait 5 minutes before you reconnect the power
cable. If the blinking reoccurs, contact Philips TV
Consumer Care.
