Troubleshooting guide

Digital broadcasts cannot be received.

¾ Digital broadcast may not have started in your region yet.

¾ The aerial may not be pointing in the direction of the TV station,

or the direction of the aerial may have changed due to strong

winds or vibration. If problem persists consult your local TV

aerial installer.

After DVB Auto Setup only some or no DVB

channels are found.

¾ Check to ensure your area is covered by DVB transmissions.

¾ Check that the aerial and antenna cable are designed for DVB.

If you live within 5-10 km of DVB transmission towers, a

combined VHF/UHF aerial should be adequate. Outside this

area, separate VHF and UHF aerials provide superior reception

performance. (> 8)

Picture regularly breaks up on some channels.

“No Signal” message is displayed.

¾ Check “Signal Condition”. If “Signal Quality” or “Signal Strength”

are displayed in red or constantly changing, check aerial. If

problem persists consult your local TV aerial installer. (> 60)

¾ Check that the aerial and antenna cable are designed for DVB.

¾ Interference (known as impulse noise) from household

appliances such as light switches, fridges etc. may cause

picture break up and/or audio distortion. Use a high quality

quad shielded coaxial cable fly lead between this unit and

antenna wall socket to minimise impulse noise pickup. If

problem persists consult your local TV aerial installer.

¾ Check aerial connection.

¾ Adjust the aerial reception with “DVB Manual Tuning” in the

Setup menu. (> 59)

Picture very infrequently breaks up on some or

all channels.

¾ Electrical atmospheric interference caused by local or distant

lighting storms or heavy rain with wind in “leafy” locations may

cause pictures to break up and audio to mute or distort

momentarily.

¾ Impulse noise interference from an infrequently used electrical

appliance, or a passing vehicle or lawn mower with a “noisy”

ignition system.

Data broadcasts cannot be received.

¾ If Italy is selected in Country setting, data broadcasts cannot be

received.

VIERA Link doesn’t work.

¾ Check the HDMI cable connection. Check that “HDMI” is

displayed on the front display when the power for the main unit

is set to On.

¾ Make sure that “VIERA Link” is set to “On”. (> 63)

¾ Check the “HDAVI Control” settings on the connected device.

¾ Some functions may not work if depending on the version of

“HDAVI Control” of the connected equipment. This unit supports

“HDAVI Control 5” functions.

¾ If the connection for the equipment connected with HDMI was

changed, or if there was a power failure or the plug was

removed from the household mains socket, “HDAVI Control”

may not work.

In this case, perform the following operations.

1 When the HDMI cable is connected to all equipment with the

power on, turn the TV (VIERA) on again.

2 Change the TV (VIERA) settings for the “HDAVI Control”

function to off, and then set to on again. (For more

information, see the VIERA operating instructions.)

3 Switch the VIERA input to HDMI connection with this unit,

and after this unit’s screen is displayed check that “HDAVI

Control” is working.

The operation on this unit (music playback etc.)

is interrupted.

¾ The operation on this unit may be interrupted when you press

buttons on the TV remote control that do not work for VIERA

Link functions.

To return all the settings other than the main ones

settings except for the ratings level, ratings PIN, language

settings, Slideshow Settings and clock settings, etc. return to

the factory preset. The timer recording programmes are also

¾ Select “Yes” in “Default Settings” in the Setup menu. All the

settings other than the tuning settings, clock settings, country

settings, language settings, disc language settings, ratings

level, ratings PIN, remote control code, etc. return to the factory

presets. The timer recording programmes are also cancelled.

(> 65)

country setting screen appears. All the settings except for the

ratings level, ratings PIN, remote control code and clock

settings, etc. return to the factory preset. The timer recording

programmes are also cancelled.

To reset the ratings level settings

¾ While the disc tray is open, press [DRIVE SELECT] to select

the DVD drive, then press and hold [¥ REC] and [1] on the

main unit at the same time for 5 or more seconds.
