1 Caution for AC Mains Lead

4

SA-PM19E / SA-PM19EB / SA-PM19EG

2 Before Repair and Adjustment

Disconnect AC power, discharge Power Supply Capacitors C506, C507, C508, C584 & C311 through a 10Ω, 5W resistor to ground.
DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices.
After repairs are completed, restore power gradually using a variac, to avoid overcurrent.

· Current consumption at AC 230V, 50 Hz in NO SIGNAL mode should be ~300 mA. (For E, EG)

· Current consumption at AC 230V - 240V, 50 Hz in NO SIGNAL mode should be ~300 mA. (For EB)

3 Protection Circuitry

The protection circuitry may have operated if either of the following conditions are noticed:

· No sound is heard when the power is turned on.

· Sound stops during a performance.

The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are
"shorted", or if speaker systems with an impedance less than the indicated rated impedance of the amplifier are used.

If this occurs, follow the procedure outlines below:

1. Turn off the power.

2. Determine the cause of the problem and correct it.

3. Turn on the power once again after one minute.
Note:
When the protection circuitry functions, the unit will not operate unless the power is first turned off and then on again.

4 Handling the Lead-free Solder

4.1. About lead free solder (PbF)

Distinction of PbF P.C.B.:

P.C.B.s (manufactured) using lead free solder will have a PbF stamp on the P.C.B.

Caution:

· Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70°F (30 - 40°C) higher. Please

use a high temperature soldering iron. In case of soldering iron with temperature control, please set it to 700 ± 20°F (370 ±
10°C).

· Pb free solder will tend to splash when heated too high (about 1100°F/600°C).

· When soldering or unsoldering, please completely remove all of the solder on the pins or solder area, and be sure to heat the

soldering points with the Pb free solder until it melts enough.

5 Precaution of Laser Diode

Caution :

This product utilizes a laser diode with the unit turned "ON", invisible laser radiation is emitted from the pick up lens.
Wavelength : 780 nm
Maximum output radiation power from pick up : 100 µW/VDE
Laser radiation from pick up unit is safety level, but be sure the followings:

1. Do not disassemble the optical pick up unit, since radiation from exposed laser diode is dangerous.

2. Do not adjust the variable resistor on the pick up unit. It was already adjusted.

3. Do not look at the focus lens using optical instruments.

4. Recommend not to look at pick up lens for a long time.

ACHTUNG :

Dieses Produkt enthält eine Laserdiode. Im eingeschalteten Zustand wird unsichtbare Laserstrahlung von der Lasereinheit
abgestrahlt.
Wellenlänge : 780nm
Maximale Strahlungsleistung der Lasereinheit :100µW/VDE
Die Strahlung an der Lasereinheit ist ungefährlich, wenn folgende Punkte beachtet werden:

1. Die Lasereinheit nicht zerlegen, da die Strahlung an der freigelegten Laserdiode gefährlich ist.

2. Den werkseitig justierten Einstellregler der Lasereinhit nicht verstellen.

3. Nicht mit optischen Instrumenten in die Fokussierlinse blicken.

4. Nicht über längere Zeit in die Fokussierlinse blicken.

ADVARSEL :

I dette a apparat anvendes laser.

CAUTION!

THIS PRODUCT UTILIZES A LASER.
USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT
IN HAZARDOUS RADIATION EXPOSURE.

6 Handling Precautions For Traverse Deck

The laser diode in the traverse deck (optical pickup) may break
down due to potential difference caused by static electricity of
clothes or human body.

So, be careful of electrostatic breakdown during repair of the
traverse deck (optical pickup).

l Handling of CD traverse deck (optical pickup)

1. Do not subject the traverse deck (optical pickup) to
static electricity as it is extremely sensitive to electrical
shock.

2. The short land between the No.4 (LD) and No.5 (GND)
pins on the flexible board (FFC) is shorted with a solder
build-up to prevent damage to the laser diode (Fig 1).

3. Take care not to apply excessive stress to the flexible
board (FPC board).

4. Do not turn the variable resistor (laser power
adjustment). It has already been adjusted.

Fig 1

l Grounding for electrostatic breakdown prevention

1. Human body grounding (Fig 2)
Use the anti-static wrist strap to discharge the static

electricity from your body.

2. Work table grounding (Fig 2)
Put a conductive material (sheet) or steel sheet on the

area where the traverse deck (optical pickup) is placed,
and ground the sheet.

Caution :

The static electricity of your clothes will not be grounded
through the wrist strap. So, take care not to let your
clothes touch the traverse deck (optical pickup).

Fig 2

Caution when Replacing the Optical Pickup :

The traverse has a short point shorted with solder to protect
the laser diode against electrostatics breakdown. Be sure to
remove the solder from the short point before making
connections.

mechanism.

4. Perform disassembly according to the following procedure
for disassembly.

9.23. CR16 mechanism disassembly procedure

9.23.1. Gear for servicing information

· This unit has a gear which used for checking items

(open/close of disc tray, up/down operation of traverse unit
by manually) when servicing. (For gear information, that is
described on the items for disassembly procedures.)

· For preparation of gear (for servicing), perform the

procedures as follows.

· In case of re-servicing the same set, the “ gear for servicing”
may be took off because it had been used. So, the “gear for
servicing” must be stored.

1. Remove the gear attached to top cover of CD loading
mechanism.

If no error is found, only the message, “CD TEST” appears on the display.

(*1) TPS operation (music search) detects the blank sections between music selections. Therefore, do not use tapes with the
following conditions:

· A blank section that lasts only 4 seconds or less.

· No blank sections (recording through microphones, etc.).

· Music selections that have extremely low pitches or prolonged silent sections (such as classical music).

· and/or Music recorded with fade in/out effect.

3. Insert a cassette tape to the unit.

4. Supply DC9V to the plunger, and turn the power ON and OFF. (→ Power +PL, -PL) (Cf. Fig. 5)
a. FWD PLAY: Supply the plunger power in a flash. (ON: approx. 5msec)
b. FWD FF: Supply the plunger power in a flash at PLAY mode. (ON: approx. 5msec)
c. STOP: Supply the plunger power in a flash at FWD FF mode. (ON: approx. 5msec)
d. REV PLAY: Supply the plunger power in a normal timing at STOP mode. (ON: approx. 200msec)
e. REV REW: Supply the plunger power in a flash at REV PLAY mode. (ON: approx. 50msec)
f. STOP: Supply the plunger power in a flash at FF mode. (ON: approx. 50msec)

Repeat the operation (→ FWD PLAY)
(Note) Other operation may start if a timing of supplying the plunger power is missed.

· The voltage value and waveforms are the reference voltage
of this unit measured by DC electronic voltmeter (high
impedance) and oscilloscope on the basis of chassis.
Accordingly, there may arise some error in voltage values
and waveforms depending upon the internal impedance of
the tester or the measuring unit.

· Importance safety notice :

Components identified by
characteristics important for safety. Furthermore, special
parts which have purposes of fire-retardant (resistors), high­quality sound (capacitors), low-noise (resistors), etc. are
used. When replacing any of components, be sure to use
only manufacturer´s specified parts shown in the parts list.

Caution !

IC, LSI and VLSI are sensitive to static electricity.
Secondary trouble can be prevented by taking care during

repair.

· Cover the parts boxes made of plastics with aluminium foil.

· Put a conductive mat on the work table.

· Ground the soldering iron.

· Do not touch the pins of IC, LSI or VLSI with fingers directly.
