I cannot see some programmes.	Adjust the position or direction of the antenna. Save the desired programmes in Programme tuning or Programme Manager.

The screen overlaps or there are stripe patterns on all programmes or on a specific programme.	Turn the antenna toward the broadcasting station or connect the antenna correctly in accordance with the "How to Connect an Antenna" section.
The screen shakes after the momentary appearance of vertical/horizontal lines and net pattern.	Stop using items such as wireless telephones, hairdryers, electrical drills etc. The problem is caused by high-frequency electronic devices such as another TV or strong electro-magnetic sources.
A digitally broadcasted programme stops or its screen is broken.	This happens when a signal is weak or reception is unstable. Adjust the antenna direction or check the cable connection. If the signal strength is too low in Manual Tuning, contact the broadcasting station or management office to have the signals checked.
I cannot see digital broadcasts even though I am using a cable television.	Check your subscription information with your cable television service provider or ask for the signal to be checked. (Some products do not provide digital broadcasts.)
The screen is blank or the image is blurred when an HDMI cable is used.	Check that the HDMI® cable meets the required standards.

The stereo sound is not clear on an analog programme, or there is no sound from one of the speakers.	[Applies only in countries where sound multiplex broadcasting is available.] Select Mono in Multi Audio if you are out of range or sound multiplex broadcasting is not stable. Adjust the balance as necessary with the Navigation button in Balance.
The TV sound is not synchronized with the picture, or the sound sometimes breaks up.	If this happens on only some of the programmes, it may be caused by the broadcasting company's transmission signal. Please have your broadcasting services provider (wired/cable) diagnose the problem.
The volume changes when I change the programme.	The volume of different broadcasting stations' transmission output may vary. Set Auto Volume to On.
The sound does not work or only the background music is played in some programmes. (Programmes produced for export by broadcasting companies)	Set your language preference in LanguageAudio Language.
The sound does not play when I connect to the HDMI/USB port.	Check that you are using a high-speed HDMI® cable. Check that the USB and USB cable versions are 2.0 or higher. Use a normal music file (*.mp3).

Check that the current screen resolution supports the PC input. To use dual monitors, check that the PC or notebook supports dual-monitor mode. Reconnect the HDMI cable.
The sound does not play when the PC is connected with an HDMI cable.	Contact your video card manufacturer to check the HDMI audio output. (Video cards designed for use with DVI format files need to be connected separately with an audio cable.)
