Anyone Repair Laser Disc Machines?

[1ziggi1]

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.

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 $$$.

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.

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.

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.
