Pioneer LC-V300 LaserKaraoke Autochanger

The service documentation seems to indicate that the autochangers store their last reported errors internally. Resetting that memory must be performed before putting the units back into service by opening the door, holding the up and down buttons at once and powering the system on. When the indicator lamp blinks you close the door and the autochanger reinitializes.

With that fixed I figured out why I could not get both autochangers to work when connected. The service documentation indicates that changer 1 addresses discs from 01 to 72 and changer 2 from 201 to 272. As it turns out I only got the second unit responding then I used the range 301 to 372. The service documentation also mentions a "wired remote jig" that takes the place of the autochanger commander and allows for manual control of basic and enhanced player functions like play, stop, side, chapter select, frame search, fast forward.... I did not however find a depiction of this wired test tool or a part number but this is MUCH more promising than being stuck with the commander.

I am still unable to get either player to play a disc. I have however learned that the "BGV" mode when enabled reserves slots 71 and 72 in the first autochanger and supposedly plays whatever disc is in there when the system is idle.

Hello, I recently purchased a LC-V80TL, 250 lasedisc changer at a going out of business sale here in Japan. Like you, i can't find much information about it. Luckily, it works well, I'm just stuck with 250 foreign karaoke laserdiscs. I would be interested in sharing information for operation and such.

Single tower unit, same controller and you have all the additional karaoke support components including the coin acceptor and amplifier.
You are correct in that there seems to be no documentation but at least the manual for the controller should be the same.
Unfortunately I've had a server crash about two weeks ago and I do not have access to most of my data currently. I ended up spending something like $15 to buy a PDF copy of the manual online.
