Nakamichi OMS7 cd player not working

Hello guys and gals. I have an old Nakamichi OM7 (not the II) that has stopped working. Sometimes, you put in a cd, it will play some of the first song, then gets staticky and muffled sounding. Other times it will pull the cd in, spin it to determine tracks, then just jack it back out, like it hates the cd I picked. A few years ago I had a Luxman D105u cd player that started skipping all the time and getting static, I replaced the laser pickup, and it was fine. This Nakamichi is far more complicated inside (that Luxman cd player was empty inside) and I can't find parts for it. Anyone have any suggestions on repairing it? Do you know of anyone who carries parts still?

Yep, A great cdp in it's day. I have the same generation OMS-4 with the same problem. My best guess is it's laser tracking failure (pick up failure). Or it could be the logic controller portion that fails also. Lot's of these are just plain wearing out due to age. It uses the a Sony KS-**** laser pick up assembly with real glass optics. Almost impossible to find and when you do they are pretty pricey. You could see what a reputable repair place might be able to do for you, but honestly as much as I loved those generation cdp's, newer units better them in many if not all regards. Had the top off mine not too long ago and WOW what a solidly built, well designed unit. You just don't see that attention to detail anymore until you hit the ultra high-end stuff.
Good luck perhaps it's something simpler and won't cost much to repair. But, I doubt it, it's a Nak, parts are scarce and competent people aren't in every repair shop. I've been looking for a donor player for a few years and they seem to exhibit the same problems. I want to get it working for old time sake, but I'm not spending an arm and a leg on it.

Toss it in the garbage....simply not worth it.CTC BBQ Amplifier, Sonic Frontiers Line3 Pre-Amplifier and Wadia 581 SACD player. Speakers? Always changing but for now, Mission Argonauts I picked up for $50 bucks, mint.

ES labs wants $350 for the laser pickup. That is more than I paid for the entire deck on ebay.Alex Cagann

Move the decimal point to the left and it would be worth it. At that price it makes a nice paper weight
