Sound
No sound or poor sound quality
If no audio signal is detected, the TV 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 TV 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 TV
to display content from an HDMI device.
• If the TV 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 TV and power reboot your source
device.
• If the picture and sound of a device connected with
HDMI is distorted, check if a different
HDMI Ultra
HD
setting can solve this problem. In Help, press the
colour key
Keywords
and look up
HDMI Ultra
HD.
• 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 TV 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 TV.
• Make sure that the audio and picture file formats are
supported by the TV.
Choppy playback of USB files
• The transfer performance of the USB storage device
may limit the data transfer rate to the TV which
causes poor playback.
Network
Wi-Fi network not found or distorted
• Microwave ovens, DECT phones or other Wi-Fi
802.11b/g/n/ac devices in your proximity might
disturb the wireless network.
• Make sure that the firewalls in your network allow
access to the TV'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.
Poor quality when watching streaming video
• The image/sound quality of stream video is
depending on the original video content provided by
streaming video apps.
• To ensure the best experience of watching
streaming videos, a fast and stable network
connection is essential. The recommended network
connection speed for the streaming videos are as
follows:
- Standard image quality (SD): 5 Mbps
- High image quality (HD): 10 Mbps
