44DVB TroubleshootingSome problems will only occur when viewing DVB channels. Due to the different techniques involved in digitalreception, DVB signal quality can be poor even if you appear to have a strong signal when viewing analogueprogrammes.The DVB system requires a good quality signal to provide the best picture. When viewing analogue pictures, interferencesuch 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 madeup of large blocks, or to freeze intermittently. If the picture disappears completely, this could mean that signal qualityis very poor. If this happens often, you may need to improve your aerial system to provide a better signal. This TVcontains a complex microprocessor which enables you to view enhanced digital services. Occasionally this devicemay need to be reset. This can be done by pressing the standby button on your remote control.SymptomsNo DVB channels listed in the TV Guide after AutoSetup.Blocky interference.Picture freezes intermittently.I have a good aerial system, but still cannot receiveDVB stations.ChecksCheck that DVB transmissions are available from thetransmitter you are currently using.
