Due to the different techniques involved in digital reception, DVBsignal 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 assignal 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 freezeintermittently. If the picture disappears completely, this could mean that signal quality is very poor. If this happens often, you mayneed to improve your aerial system to provide a better signal. This TV contains a complex microprocessor which enables you toview enhanced digital services. Occasionally this device may need to be reset. This can be done by pressing the standby buttonon your remote control.SymptomsNo DVB channels listed in the TVGuide after Auto Setup.Blocky interference.Picture freezes intermittently.I have a good aerial system, butstill cannot receive DVB stations.ChecksCheck that DVB transmissions are available from the transmitter you arecurrently using.
