Wrong again.

you would be surprised. people have older units they like and they do
try to get them fixed.

A lot of times its the belts on the load mech. tray won't go in all the
way and then jams.

Also, laser problems will affect the spindle motor. Since its a servo in
effect, if the laser is not reading right the motor may not spin
properly either.

The first thing is to clean the laser. Taking the cover off the laser if
possible helps. I spray it down with canned air on the top and into the
side to try to get to the mirror inside and the sensor.

They i use optical head cleaner in a can and give it a quick squirt and
lightly brush off the top of the lens with a qtip.
you have to let it dry awhile before you try it.


Its never 100%, but i have brought many back to life by cleaning like this.

Yea, you can buy a POS DVD/CD player with no display for $30 on sale.
you get what you pay for.

If the brushes are still intact, i have disconnected the motor from the
driver and gave it full 8 to 12 volts and let it scream away.
If your lucky, it will re-seat the brushes or clean off the commutator.

Its not a high percentage repair, but what do you got to lose?
You might have to jump start it to get it spinning. I usually do
this with a variable supply and ramp up the voltage gradually.

DVD players usually do not work as nicely for CD's. I mean for FF and
such.

You don't need to pull the spindle to do this. Just remove the wires
from the motor to the control board and hot wire the motor while its
still in place.

Replacing the motor can be a little dicey. Always mark how much of the
shaft sticks out of the clamper so you can duplicate the setting.
if your too high it will rub, too low and the laser won't focus right.
Its a trick to gently pry the spindle off without breaking it or
distorting its dimensions. Its held on by compression only.
I try to use two flat blade screwdrivers and pry from opposite sides if
possible.


On some units, you can buy a complete laser sled with motors aftermarket
if its one of the more common sony ones.

If the problem is a dirty commutator, that might fix it. If the problem
is a bad solder joint where the armature wires are connected to the
commutator segments, it won't. Every time the motor stops with the
"dead" segment under the brush, you'll have to push-start it. Once it's
running, inertia will keep it going and it'll run just fine. Until next
time.

What's wrong?

Think the Pioneer product doesn't exist?

Think it doesn't sound good?

Operative word being "try".

If it does it once, it will probably do it again, after you fix it.

Replacment lasers generally cost more than whole players.

But for $60 you can get one with a nice display. Been there, done that.

by the time you pay minimum order or shipping, its going to be an
expensive motor unless you need other items from them.

No, the whole idea of cleaning it is with a high speed blast.
normal playing will not do this. Like i said, its a long shot
but possible

Bob, most Sony spindle motors have a pair of slots on the bottom where the brushes are.
Spray a little deoxit D5 in the slots, run the motor for a few seconds in each direction
with a 5 volt power supply, and test - it should start with 1 1/2 volts or less on it. Repeat if
necessary. This fixes about 90% of the no-start problems I encounter. The other 10%
require replacement of the motor, or more commonly the entire mechanism. MCM stocks
the more common Sony mechanisms; some are as cheap as $15. Andrews has all of them
but you may need an account to buy from Andrews - they're an OEM parts distributor for
Sony and a bunch of other companies.

Typically you have to unsolder the spindle motor and sled motor from the board under
them to get at the bottom of the motor to do this procedure. Do NOT unplug the laser from
the board it's plugged into; it can easily be destroyed by static electricity when it's
disconnected. New ones come with a solder bridge to prevent this; only after you connect
the new laser can you safely remove the solder bridge.

Best, Fred

Yes, but not often on CD spinners. Back in the '60's when we were
rewinding Mabuchi's for slot-cars, now...
