The objective lens going up and down is normal. However, the laser does not appear to be lasing. Since this unit uses a HeNe (helium neon) gas tube laser, the beam should be a very bright red light. However, there could be a separate interlock switch for the laser that's not being engaged or that interlock switch may be faulty. Or, assuming a separate laser interlock switch that's good, the laser may be coming on when the door is closed, but the disc isn't being read because the lens may be dirty. All it takes is just enough accumulated dust or dirt to intercept the beam to prevent the player from detecting the disc and the optical servo circuit from locking onto the track.

It was the switch on the hinged side of the door that was not telling the player that the door was closed
