My Yamaha disc player (CDC-765)is 7-8 years old and has always performed flawlessly until now. At any any given time, the player gets "stuck" repeating the same note over and over until I manually advance it. It usually will play 5 or 10 songs before this happens. It doesn't matter what cd I'm playing so the problem is not the cd. If anyone can offer a possible solution or if a repair shop is needed, I would be most greatful. Thanks
