Anyone Repair Laser Disc Machines?

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.

try over at alt.video.laserdisc Guy by the name of Kurtis repairs machines, has machines for sale, and is generally a nice guy.

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.
