• Reset all TV settings, go to (Home) > Settings
> General settings > Reinstall TV.
• Check the connections of the source/input devices.
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.
Poor picture from a device
• Make sure that the device is connected properly. Make
sure that the device's output video setting is the highest
possible resolution if applicable.
• Restore picture style or change to another picture style.
Picture settings change after a while
Make sure that Location is set to Home. You can change
and save settings in this mode.
(Home) > Settings > General settings > Location
A banner appears
If an on screen promotion banner appears occasionally
or the Picture style automatically switches back to Vivid
at startup, the TV is in Shop location. Set the TV to Home
location for use at home.
(Home) > Settings > General settings > Location

screen, with black bars on the top and bottom or left and
right side of the screen, press (Home) >
Settings > Picture > Picture Format > Fill screen.
• If the picture size changes all the
time, press (Home) > Settings > Picture > Picture
Format > Fit to screen.

try to check the signal resolution and output type of the
connected device, press (Home) > Settings
> Picture > Picture Format > Original.
Computer picture is not stable
Make sure that your PC uses the supported resolution
and refresh rate.
22.7. 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
22.8. HDMI - UHD
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.
• 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 off Ultra HD for this HDMI
connection.
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 > User
manual, press the colour key
