Dvb Troubleshooting - Daewoo DUB-2850GB, DUB-2842GB Instruction Manual

DVB TROUBLESHOOTING

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