Troubleshooting
In DVB-T mode
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 stand-by button on your remote control or the power switch on the front panel.

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.
