Sansui cd-x711 cd-player several problems!
Hi!
I have a sansui cd-x711 cd-player from the late 80's that have several problems. When a disc is loaded the lens from the pickup goes up and down a couple of times before reporting "no disc". After consulting another owner the startup sequence is supposed to be: drawer closes, and spindle/motor engages the disc, the disc starts to spin, the laser head tries to focus, then the disc starts to play. In my case the disc never starts to spin, the optical pickup that is of the linear tracking type (coils and magnets), whatever starting position is, doesnt move to the center. Both the motor and the coils are connected to a "RF/SERVO(f) board. What could the problem possibly be? Would be nice to get it going, it is a very nice unit. Dual power supplies, optical and coaxial outputs, balanced xlr outputs, and should have a very nice sound too. All help appreciated, /Erik |
