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 leakage 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)

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.

EMISSION
T o check the emission of the laser diode during adjustments, nev er
view directly from the top as this may lose your eye-sight.
3. PRECAUTIONS FOR USE OF OPTICAL
PICK-UP (KMS-260A)
As the laser diode in the optical pick-up is easily damaged by static
electricity, solder the laser tap of the fle xible board when using it.
Before disconnecting the connector, desolder first. Before connecting the connector, be careful not to remove the solder. Also
take adequate measures to prevent damage by static electricity.
Handle the flexible board with care as it breaks easily.

4. Use the following tools and measuring devices.
• Check Disc (MD) TDYS-1
(Part No. 4-963-646-01)
• Test Disc (MDW-74/AU-1) (Part No. 8-892-341-41)
• Laser power meter LPM-8001 (Part No. J-2501-046-A)
or MD Laser power meter 8010S (Part No. J-2501-145-A)
• Oscilloscope (Measure after performing CAL of prove)
5. When observing several signals on the oscilloscope, etc.,
make sure that VC and ground do not connect inside the oscilloscope.
(VC and ground will become short-circuited)
6. Using the above jig enables the waveform to be checked without the need to solder.
(Refer to Servicing Notes on page 4)
7. As the disc used will affect the adjustment results, make sure
that no dusts nor fingerprints are attached to it.
Laser power meter
When performing laser power checks and adjustment (electrical
adjustment), use of the new MD laser power meter 8010S (Part
No. J-2501-145-A) instead of the conventional laser power meter
is convenient.
It sharply reduces the time and trouble to set the laser power meter
sensor onto the objective lens of optical pick-up.
5. CREATING CONTINUOUSLY-RECORDED DISC
* This disc is used in focus bias adjustment and error rate check.
The following describes how to create a continuous recording
disc.
1. Insert a disc (blank disc) commercially available.
2. Turn the JOG dial and display “CREC MODE”.
3. Press the
Display “CREC (0300)” and start to recording.
4. Complete recording within 5 minutes.
5. Press the [NO,CANCEL] button and stop recording .
6. Press the [MDEJECT] button and remove the disc.
