cause severe injury, irreparable damage to the TV or
void your warranty.

Sound issues
There is a picture but the sound quality is
poor:
Note
•
If no audio signal is detected, the TV will automatically
switch the audio output off - this does not indicate a
malfunction.
• Check that all cables are connected
properly.
• Check that the volume is not set to 0.
• Check that the sound is not muted.
• Check that the sound settings are set
correctly.
There is a picture, but sound only comes from
one speaker:
• Check that the sound balance is set to the
centre.
HDMI connection issues
There are problems with HDMI devices:
• 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, try
switching the source from one device to
another and back again.
• If there are intermittent sound disruptions,
check that the HDMI device output
settings are correct.
• If you use an HDMI-to-DVI adapter or
cable, check whether the audio cable that
comes with the product is connected to
AUDIO (mini-jack only).
