20.4. Troubleshooting
Switch On and Remote Control
The display 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 display on, off or to standby,
you hear a creaking sound from the display chassis. The
creaking sound is due to the normal expansion and
contraction of the display as it cools and warms up. This
does not affect performance.
Display does not respond to the remote control
The display requires some time to start up. During this
time, the display does not respond to the remote control
or display controls. This is normal behaviour.
If the display 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 display 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 display.
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 Display Consumer Care.

Computer picture is not stable
Make sure that your PC uses the supported resolution
and refresh rate.
Sound
No sound or poor sound quality
If no audio signal is detected, the display automatically
switches the audio output off — this does not indicate
malfunction.
• Make sure that the sound settings are correctly set.
• Make sure that all cables are properly connected.
• Make sure that the volume is not muted or set to zero.
• Make sure that the display audio output is connected
to the audio input on the Home Theatre System.
Sound should be heard from the HTS speakers.
• Some devices may require you to manually enable
HDMI audio output. If HDMI audio is already enabled,
but you still do not hear audio, try changing the digital
audio format of the device to PCM (Pulse Code
Modulation). Refer to the documentation accompanying
your device for instructions.
