Hey, I have had this Panasonic SC-DK1 dvd mini system for five years now. Just recently the display goes blank and the dvd player won't read some disks until after the unit is wormed up after playing another disk for a while. I think the laser is going out but not sure. It plays all music cd's all the time. Where can I go to get the laser replaced or is that not possible? It is a hell of a system and I would hate to have to get a new one. Then I have a bunch of speakers with nothing to do.
