43Some 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,interference such as signal reflection from nearby buildings or mountains causes ‘ghosting’, but still provides aviewable picture. For the DVB system, interference such as this can disrupt the flow of data causing the picture toappear to be made up of large blocks, or to freeze intermittently. If the picture disappears completely, this couldmean that signal quality is very poor. If this happens often, you may need to improve your aerial system to providea 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 remotecontrol.SymptomsNo DVB channels listed in theTV Guide after Auto Setup.Blocky interference.Picture freezes intermittently.I have a good aerial system, but still cannot receiveDVB stations.ChecksCheck that DVB transmissions are available from the transmitteryou are currently using.
