Panasonic AG-LD20 Laserdisc player not playing LD's?

[Luke Perry]

Hi, I have a Panasonic multidisc LD player that plays CD's, cd video,
and Laserdiscs. It plays the CD's just fine but for some reason it is
not playing the laserdiscs. I took the cover off to observe what is
happening and it appears that the disc starts to spin up, then it
stops after 2 seconds or so.

I read about a similar problem with a Pioneer player and someone
suggested cleaning the rubber clamping thing that is part of the
spindle motor and I tried that but it is still doing the same thing.

Any hints on what could cause this? Could it be out of alingment or
anything else?


thanks
