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.

.T’he direction of movement of the pick-up (outer groove or

inner groove) can changed by changing the battery polarity.

The current during sled motor operation varies

according to the positional relationship of gears

(11 Oandll l).

If the current exceeds 20-50 mA , remove the

gear (lll)andgear(ll O).

Apply a small amount

of a FLOIL ( G-474B ) bonding

materials to the chassis shafts.

Install the gears as shown in the illustration.

Resetting the pick-up to the home position

The LIMIT switch is switched ON by the projection of the

rack gear secured to the returned pick-up, after which the

sled motor continues to operate (by the circuit)

for

approximately 20 -

30 milliseconds ; there is then again a

reverse operation, and movement to the position at which

the switch is switched OFF.

Rotation continues

for about 20- 30 milliseconds after the

switch is switched OFF,

and then the pick-up stop at home

position.

PARTS LIST

PRODUCT SAFETY NOTICE

Each precaution in this manual should be followed during servicing. Components identified with the IEC symbol ~ in the parts list

and the schematic diagram designate components in which safety can be of special significance. When replacing a component

identified ~, use only the replacement parts designated, or parts with the same ratings of resistance, wattage or voltage that are

designated in the parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed

parts are acceptably insulated from the supply circuit before returning the product to the customer.

CAUTION :

Regular type resistors and capacitors are not listed. To know those vakses, refer to the schematic diagram.

Regular type resistors are less than l/4W carbon type and O ohm chip resistors.

Regular type capacitors are less than 50V and less than 1000PF type of Ceramic type and Electrical type.
