Off until reception improves.

This is a characteristic of liquid 
crystal panels and is not a 
problem. The liquid crystal panel 
is built with very high precision 
technology giving you fine 
picture details. Occasionally, a 
few non-active pixels may 
appear on the screen as a fixed 
point of blue, green, or red.
Please note this does not affect 
the performance of your LCD.

If there is a problem with your TV please refer to the table below to determine the symptoms, then carry out the suggested check.
If this does not solve the problem, please contact your local Panasonic dealer, quoting the model number and serial number (both
found on the rear of the TV).

Some problems will only occur when viewing DVB channels. Due to the different techniques involved in digital reception, DVB
signal quality

 

can be poor even if you appear to have a strong signal

 

when viewing analogue programmes.

The DVB system requires a good quality signal to provide the best picture. When viewing analogue pictures, interference such as
signal reflection from nearby buildings or mountains causes ‘ghosting’, but still provides a viewable picture. For the DVB system,
interference such as this can disrupt the flow of data causing the picture to appear to be made up of large blocks, or to freeze
intermittently. If the picture disappears completely, this could mean that signal quality is very poor. If this happens often, you may
need to improve your aerial system to provide a better signal. This TV contains a complex microprocessor which enables you to
view enhanced digital services. Occasionally this device may need to be reset. This can be done by pressing the standby button
on your remote control.

No DVB channels listed in the TV
Guide after Auto Setup.

Blocky interference.
Picture freezes intermittently.

I have a good aerial system, but
still cannot receive DVB stations.

Check that DVB transmissions are available from the transmitter you are
currently using. If not, try directing the aerial at another local transmitter.

Check analogue transmissions. If picture quality is poor, you will need to
improve or change your aerial system to receive DVB channels. Consult a
local installer.

Blocky interference indicates that the signal quality is poor.
You should consider improving your aerial system.
To check the quality of your signal use the Signal Quality feature (see page
26).
Good quality signal – indication is green.
Poor quality signal – indication is red.

If you have tried the previous solutions and are still unable to
receive DVB channels, you may need to provide dedicated
aerial feeds to the TV and other equipment.
This can be implemented using an
aerial splitter or separate aerials.
