tv been fine, then out of the blue while watching it started to automatically flick through the channels without hoilding the signal of one. would even skip auto through the menu options. only way it would stay on a channel was if you held one of the channel select buttons down. would sometimes hold one on its own for a few minutes then start again. tv never given a problem before so seems rather strange that its started so suddenly. what should we do. please help..have 6 kids at it is raining alot at the moment.
