    I have a Pioneer CLD95 Laser Disc that does not recognize any disc. I
    have not done anything to it but look and read. I have done
    electronics for the last 30 years so I know better than to mess with
    something that I do not have a service manual or the right test
    equipment for.
    I was just hoping to determine whether it was worth repairing or not
    so I am looking for someone who knows what they are doing and is close
    to Florida to repair it.
    Is there any way to determine what might be the problem or how much it
    would cost to repair? The machine was working perfect one day then the
    next day it just stopped. Also is there anywhere I might obtain a
    service manual for this model since I plan on keeping either this one
    or just replacing it with the same model?

    Sling it out and buy a new one.
    Will be cheaper in the long run.
     
  3. Do you even know what a LaserDisc is? :)

    I'd love to know where you can go buy a new one. I haven't seen laserdisc
    players on store shelves in over a decade. These things are getting scarce
    and good ones are $$$.
     
  5. He probably doesn't even know what a LaserDisc "machine" is. Probably
    thinking of DVD.

    Ok this is fine he doesn't have a clue what a Laserdisc is but this
    doesn't help my problem.
     
  7. True. But there was another reply that suggested the cost to repair if it
    was a bad pickup, would approach the cost of a replacement LD player on eBay.

    You've cleaned the lens. Reseating connectors shouldn't hurt. Checking
    power supply voltages would be helpful if they are marked.

    The test that needs to be done is to measure the lsaer output power with a
    calibrated power meter. I don't know what the spec is but a measurement
    of 1 mW or more would probably mean it's OK, a measurement of under 0.1 mW
    would likely mean it's bad.

    Does the laser do a calibration of sorts and look for media before the
    control spins up the disc? If I recall the OP mentioned the disc didn't
    move. I don't recall if the OP mentioned anything about the sled having
    movement or if the device made any noise or otherwise just sat there and
    did nothing.

  10. From private email, it does try to focus but does not spin the LD or CD.

    I see that someone on the LD newsgroup commented that these pickups rarely
    go bad. As usual, a service manual and a quick check of some test points
    would probably narrow it down.

    I thought that back then the disc was not detected by the laser, but
    by a beam interruption led/opto-tr pair. If thats right, you may be
    looking at a problem with the beam break thing, control system or
    possibly spindle drive.
