I have no motion, i.e play fast forward and reverse.. By looking at my
other deck that works , it seems that the white plastic gears are
not engaging. Is that a bad motor, a belt or somethign else

TIA

Who do you recommend to repair this?

I think I've heard of bad lamps causing this...

Are you trying to be funny?

Definitely not - in addition to motion sensing, they may use lamps as a sort
of fuse involving the front panel functions. In other words if a Play
indicator lamp would go out, the mechanical functions might be inhibited
altogether. I know it sounds stupid, and I'm trying to remember something
another tech told me 15 years ago, so I'm sorry I can't be more specific.
Just wanted to alert you to the possibility.

Concur. Not a Nakamichi, but had a similar problem with an old Accuphase
power amp. They have a small fuse-like lamp to illuminate the analogue VU
meters. I lost a channel at the same time one of the lamps blew (but didn't
make the connection at the time). Took me a while to figure out what caused
the channel to go. After a bit of digging around I found out that the lamp
doubled as a kind of fuse (still don't know what it was actually
protecting), but I replaced it with a $1.00 lamp from the US and the channel
recovered.

Cheers
