pioneer laser disc player inoperative

I would first check the spindle motor. Try giving the disk a spin manually and see if it runs.

I don't remember if this is the same model, but one of the early players with a laser diode had a problem with the switch that determined whether an LV or CD was inserted. If you played a CD, the unit would then refuse to play an LV, until you took off the cover and manually reset the mechanism (flipped the tray).

Try cleaning the laser lens. Many (most?) CD/DVD players won't spin up unless they get an initial reflection from the disk.

tried cleaning with no results. however the laser does glow while searching for focus etc.

nope.tried that when i tested to see if motor froze up.

good thought. i believe i am on side #1. w/a laser disc installed pressing button for side#2 lights the indicator but nothing happens mechanically. both lights remain lit. i wonder which screws i need to remove to seperate the mechanical assembly from the top of the boards. thats because there's no removeable bottom plate under the boards for me to take voltage readings.

For what I suggest, you need only remove the top cover.

Does it actually achieve focus lock? I.e., the lens should pop up once and stay fixed, not repeatedly move up and down trying to find focus.
