Poor reception
If the TV picture is distorted or variable in quality, the
input signal might be poor. A weak digital signal is
seen as a picture that is breaking up in square blocks
and freezes occasionally. Much sooner than a bad
analogue signal, a bad digital signal will fall away.
• Check if the antenna cable is properly connected.
• Large loudspeakers, unearthed audio devices, neon
lights, high buildings and other large objects can
influence reception quality when you are using an
antenna. Try to improve the reception by changing
the antenna direction or moving devices away from
the TV. Bad weather might deteriorate the reception.
• Check if all connections, to and from your devices,
are properly connected.
• If reception on only one channel is poor, fine-tune
this channel with Analogue: manual installation. (Only
for analogue channels)
• Check if the incoming digital signal is sufficiently
strong. While watching a digital channel,
press OPTIONS and select Status and
press OK. Check the Signal strength and Signal
quality.

Sound
No sound or poor sound quality
• Check if the sound settings of the TV are OK, press
the volume or mute key.
• If you use a digital receiver (set-top box), check if
the volume on this receiver is not set to zero or mute.
• Check if the TV - the audio signal - is properly
connected with the Home Theatre System, if you use
such a system for the TV sound. Check if you
connected the HDMI cable to an HDMI1
ARC connection on the Home Theatre System.
• 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 (Home Theatre
System) speakers.
Sound with loud noise
If you watch a video from a plugged in USB flash drive
or connected computer, the sound from your Home
Theatre System might be distorted. This noise is heard
when the audio or video file has DTS sound but the
Home Theatre System has no DTS sound processing.
You can fix this by setting the Digital out format of
the TV to Stereo.
Press (Home) > Settings
> Sound > Advanced > Digital out format

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.
• This is an Ultra HD TV. Some older devices -
connected with HDMI - do not recognise an Ultra HD
TV electronically and might not work correctly or
show distorted picture or sound. To avoid the
malfunctioning of such a device, you can set the
signal quality to a level the device can handle. If the
device is not using Ultra HD signals, you can switch
