I've had a Sony 5-Disc DVD player model# DVP-C660 for three years now. I've never had a problem with it until now. Whenever I put in a disc it gives me a "No Disc" message. I have to open and close the disc tray up to ten times for it to finally accept the disc and play it. This is not a problem with my DVDs since this happens with every one I have. Is there anything I can do myself through the service menu without having to take it in to get repaired and be charged more than I paid for it?
