SERVICING NOTES
SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microamperes.).
Leakage current can be measured by any one of three methods.
1. A commercial leaka ge tester, such as the Simpson 229 or RCA
WT -540A. Follo w the manufacturers’ instructions to use these
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate lowvoltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery
operated digital multimeters that have a 2 V A C range are suitable. (See Fig. A)

Parts on Set
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated
by the charged electrostatic load, etc. on clothing and the human
body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
on the disc reflective surface by the objective lens in the optical
pick-up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be damaged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C during repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.

DISC EJECTION IN EMERGENCY
L
In case of emergency , remove the discs inside the Mec hanism Ass’y
(CD Changer) as follows:
(1) Disconnect the power of the Main Unit.
(2) Remove the Mechanism Ass’y. Refer to item
(3) Remove two top cover fastening screws at the rear of the
Mechanism Ass’y, and tak e off the Top Cover HS Ass’y . Refer
to Fig. A.
(4) Remove the left side adhesive label (Dust Seal EMA SL) on
the left side of the Mechanism Ass’y. Refer to Fig. A.
Note: Carefully remove it since it is used again later.
(5) Turn the Emergency Gear SL up or down until the disc lock
sleeve SL is lowered as shown in Fig. B.
Caution:Never use nail when turning the Emergency Gear
SL. Otherwise, the gear tooth may be broken.
(6) Raise the front section of the Mechanism Ass’y as illustrated
in Fig. B. Then carefully spread the Loading L/R MF Ass’y so
that the disc drops into the Stocker.
(7) While keeping the Loading L/R MF Ass’y spread, remov e the
discs.
Note: When removing the discs, take care not to scrape them
against other parts, to prevent damage.
(8) Re place the removed parts by reversing the above procedure.
Note: To prevent dust from entering the unit, reattach the
adhesive label on the opening for the Emergency Gear
SL.
(9) Perform the mechanism initialization as follows to clear the
disc information stored in the Mechanism Ass’y.
Press the DISC1 button while pressing the DISC5 button.
Then, the Unit enters the CD Playback mode and mechanism
Initialization operation begins and disc change operation starts.
After that, the Unit enters Standby mode.

NOTE:
• Due to standardization, replacements in the
parts list may be different from the parts specified in the diagrams or the components used
on the set.
• -XX and -X mean standardized parts, so they
may have some difference from the original
one.
• RESISTORS
All resistors are in ohms.
METAL: Metal-film resistor.
METAL OXIDE: Metal oxide-film resistor.
F: nonflammable
