When I try to open the door to my player there’s no response. The front display reads “open”, as if the operation is taking place, but no activity. I can turn the player on and off and everything is described on the display screen, but nothing mechanical takes place. Is this the end of my CLD-D704? I really hate using my spare player because I actually have to exert energy flipping the disc! Also, I lave a LD trapped in the ol’ 704. Any help would be appreciated.
