Got a Panasonic TV and had it about 8 years - over the last 3 months it seems to randomly switch to a digital 'teletext' type thing and broadcast the audio of BBC1 - exiting it spits you out at BBC1 and you loose the channel you were watching.
Each time the TV is witched on it claims new settings/channels have been detected and we need to rescan - so we do...then once done and restarts, it tells us new channels are available...etc....etc....etc....
I'm not planning on taking it apart but is this a common issue with a tv tis 'old' (previous one was 23 years old and actually gave a better picture!) or has anyone else experienced this and able to suggest a cause and repair?
Thanks.
