Default Rowe AMI R-89

I've been experiencing an intermittent problem with my Rowe AMI R-89. It plays
perfectly but at times goes into a mode where it picks up a record and places
on it on the turntable, then picks the record up again without playing it and
repeats this process.

Other times the record does start to play then this process starts before the
record has played all the way through. The first time this happened a few
months ago I tried to troubleshoot it and the problem stopped and the unit has
played perfectly since then. Today it started acting up again. Any ideas what
may be causing this problem?

Thanks,
Ray

Believe it or not I have had this before

in one case it was the spring in the motor - if you look at the upper
part where the coil and the laminations of the motor are - the small
"rotor" is supposed to move sideways a small amount when the motor is
started. This acts as a clutch so as to stop the motor promptly when
power is removed. There is a small spring on the shaft that pushes it
back out when power is applied. if this spring falls apart or loses
its spring - the rotor stays in there and engaged with the gears and
it continues spinning by its momentum and allows the motors output to
continue rotating a few degrees after power is off. this is often
enough to make it go past the cam switch, which makes the software
restart the motor and the cycle to continue over and over and over as
we have seen here


The other thing to do is replace the triac (A BT139 works well) that
drives the motor AND the opto-coupler as well. (note - Im pretty sure
that used a standard transistor type opto (4n28 type) and it worked
just as well as the triac output one that was fitted by rowe - and
would be probably impossible to get easily) I have twice seen these
go leaky internally and cause the motor to "creep" forward at a very
slow rate when turned off - this then makes them go past the cam
switch triggering an unwanted restart.



both these advices would apply to any LASERSTAR mechanism as well as
the mechanics and electronics in these areas are pretty much
identical.

If you have a hardwired remote volume/cancel/ control hooked up I
would try completely unhooking it it to see if that was the source of
the problem.
