CHECKING THE CD MECHANISM
Checking the operation of the CD mechanism
Disconnect the sled motor socket from the printed-circuit
board.
Apply a voltage of DC 0.7 V to the sled motor's
terminal.
Measure the current during sled motor operation.
The direction
of
movement of the pick-up (Outer groove
or inner groove) can be changed by changing the battery
polarity.
The current during sled motor operation varies
according to the positional relationship of gears
(107 and 108).
If the current exceeds 20-50 mA , remove the
gear ( 107 ) and gear ( 108 ).
Apply a small amount
of
a
FLOIL ( G-474B )
bonding
materials to the chassis shafts.
Install the gears as shown in the illustration.
