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.
HDMI and USB
HDMI
• Note that HDCP (High-bandwidth Digital Content
Protection) support can delay the time taken for
a display to display content from an HDMI device.
• If the display does not recognise the HDMI device
and no picture is displayed, switch the source from
one device to another and back again.
• If the picture and sound of a device connected to
HDMI is distorted, connect the device to another
HDMI port on display and power reboot your source
device.
• If there are intermittent sound disruptions, make
sure that output settings from the HDMI device are
correct.
• If you use an HDMI-to-DVI adapter or HDMI-to-DVI
cable, make sure that an additional audio cable is
connected to AUDIO IN (mini-jack only), if available.
HDMI EasyLink does not work
• Make sure that your HDMI devices are HDMI-CEC
compatible. EasyLink features only work with devices
that are HDMI-CEC compatible.
No volume icon shown
• When an HDMI-CEC audio device is connected and
you use the display Remote Control to adjust the
volume level from the device, this behaviour is
normal.
Photos, videos and music from a USB device do not
show
• Make sure that the USB storage device is set to Mass
Storage Class compliant, as described in the storage
device's documentation.
• Make sure that the USB storage device is compatible
with the display.
• Make sure that the audio and picture file formats are
supported by the display.
Choppy playback of USB files
• The transfer performance of the USB storage device
may limit the data transfer rate to the display which
causes poor playback.
Network
Wi-Fi network not found or distorted
• Microwave ovens, DECT phones or other Wi-Fi
802.11b/g/n devices in your proximity might disturb
the wireless network.
• Make sure that the firewalls in your network allow
access to the display's wireless connection.
• If the wireless network does not work properly in
your home, try the wired network installation.
Internet does not work
• If the connection to the router is OK, check the
router connection to the Internet.
The PC and Internet connection are slow
• Look in your wireless router's user manual for
information on indoor range, transfer rate and other
factors of signal quality.
• Use a high-speed (broadband) Internet connection
for your router.
DHCP
• If the connection fails, you can check the DHCP
(Dynamic Host Configuration Protocol) setting of the
router. DHCP should be switched on.
Bluetooth
Unable to pair
• Make sure the device is in pairing mode. Read the
user manual of the device.
• Keep the wireless speaker as close to the display as
possible.
• Trying to pair several devices with the display at the
same time, may not work.
Bluetooth lost connection
• Always position the wireless speaker within a range
of 5 meters from the display.
Bluetooth Audio and Video synchronisation
• Before you purchase a wireless Bluetooth speaker,
inform yourself about its quality of Audio to Video
synchronisation, commonly called 'lip sync'. Not all
Bluetooth devices perform correctly. Ask your dealer
for advice.
