Laser doesn't move?

Help,
I'm getting disk read errors. I tried running with the top off and
when I did I noticed that the laser doesn't move. When started or reset the
laser does not move back and forth on its tracks. The laser lights up and
the disk spins but the laser does not move around. It does sense a disk but
can't read it. I checked and my laser gear looks good, but the motor
driving the worm gear is not turning.
Is it normal when starting up, for the disc to make two half turns
first before it starts spinning fast? How can I check the motor that's
supposed to turn the worm gear that moves the laser? Should I be able to
read voltage from the solder pads on the motor or circuit board? - I can't.
Is there a fuse or something on the board that may be blown?
When starting up I get the electrons moving around and then the
browser screen and then Disk read error?
Should the laser move immediately to the center of the disk bed when
the PS2 is started up or turned on?
