I have a Philips DVP 3005 DVD player that has started playing up - it suddenly refuses to play certain discs, which it's played hundreds of times before. It tries to load them, then says 'no disc'. These discs work fine in other DVD players, and mine will still play other discs. I've tried using a cleaning disc, but it hasn't made any difference. The DVD player is about 3 years old and I bought it new. Does anyone have any suggestions other than 'get a new one'?
