TABLE OF CONTENTS
SAFETY CHECK-OUT
After correcting the original service problem, perform the follow-
ing 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 leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow 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" indica-
tion is 0.75 V, so analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-
amples of a passive VOM that is suitable. Nearly all battery
operated digital multimeters that have a 2 V AC range are suit-
able. (See Fig. A)

Notes on chip component replacement
· Never reuse a disconnected chip component.
· Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.

SECTION 1
SERVICING NOTES
The laser diode in the optical pick-up block may suffer electro-
static 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 emis-
sion, observe from more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
1. Turn POWER switch on with no disc inserted and make Func-
tion switch to CD position.
2. Open the lid for CD.
3. Turn on S701 as following figure.
4. Press the [
] (CD) button.
5. Confirm the laser diode emission while observing the object-
ing lens. When there is no emission, Auto Power Control cir-
cuit or Optical Pick-up is broken.
Objective lens moves up and down three times for the focus
search.

CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra-
diation exposure.
CHUCK PLATE JIG ON REPAIRING
On repairing CD section, playing a disc without the CD lid, use
Chuck Plate Jig.

MODEL TYPE IDENTIFICATION
In this set, the routing of speaker lead wires and the boards have been changed in the midway of production, and the set is grouped into the
following four types depending on the specifications.
TYPE A: Original model.
TYPE B: To the original model, the routing of speaker lead wires is changed.
TYPE C: To the type B, the print patterns of board are changed.
TYPE D: To the type C, the shapes of boards are changed.
· Model Type Discrimination
Identify each type from the part number printed on each board by referring to the following table.
Also, each board is common to type A and type B, but routing of speaker lead wires is different. For details of different places, refer to "6.
Diagrams 6-10. Printed Wiring Boards MAIN/POWER SUPPLY Section (Type A, B) " (page 42, location A-1 and B-1).

· Precaution on Replacing the Boards
The supplied boards are all type D, and therefore if the board is replaced, use the board of type D only whichever model is serviced.
However, on the type D model, the number of pins of connectors that connect MAIN board to CD board, and MAIN board to POWER
board has been changed, and accordingly the type D is not interchangeable with type A, B, and C respectively.
Therefore, if even one of MAIN, CD, and POWER boards is replaced, replace all three boards simultaneously.
