2-2. REP AIR INTRODUCTION
PREPARATION FOR CD BLOCK
1. Set a disc for repair into product.
2. Tur n the product upside down on the jig (Parts
No.*MR2021JIG). Take care that the top cover will not
damaged, especially the 4 lever s. (Refer to "How to
disassemble MD2020")
3. For the top panel will not open while repairing, remove
the connecting wires of panel motor from the connector
(J812).
4. Repair and operate it on the upside down position of
the product.
PREPARATION FOR MAIN AMPLIFIER PCB (P704)
1. Main amplifier is BTL output.
2. For removing the main amplifier PCB (P704) from the
product, remove the wire (W802) from the terminal
(WU02) of microprocessor PCB (PU04). Connect
another wire with terminal (WU02) and GND as chassis
instead of the wire (W802).
REMARK
Remove the bottom case from the product, Do not output
signals of over 1W from both channels more than 10
minutes continuously.
2-6
2-3. EXPLANA TION OF CIRCUITS
FAN OPERATION
The voltage added to the diode (D852) is depended on
the resistance of the thermistor (R857) and resistors
(R855,R858). When the temperature of the heat sink
goes up, the resistance of the thermisor (R857)
decreases, and the voltage added to the diode (D852)
increases.
1. When the temperature of the heat sink is over 70
degrees Celsius, then D852 is on, through R852, Q851
is on, and the fan starts to revolve.
2. When the temperature of the heat sink is approx. 100
degrees Celsius or more, through R853, Q853 is on,
and the product is STAND-BY status. But, if the fan
revolve normally, the temperature of the heat sink will
not be over 100 degrees Celsius and not be STANDBY status. Therefore, the procedure of the o ver heat
protection circuit check is as follows;
(1) Connect the test point (J814) with a resistor of 680
ohm.
(2) If the product is STAND-BY status, this circuit is normal.
(3) Remove the resistor of 680 ohm from the test point
(J814).
FAN OPERATION CHECK
Keep outputting 2.5W from both channels of the product.
When the bottom case is closing. If the fan revolving starts
within 10 minutes, the function is correct working.
Otherwise keep outputting 1W from both channels of the
product when the bottom case is opening. If the f an revolving
starts within 5 minutes, the function is correct working.
REMARK
Do not output over 1W when the bottom case is open.
VCC CONTROL
The regulation of primary voltage is not so higher
intentionally for decreasing the no-load loss. Therefore, this
circuit is used for the product to keep the voltage tolerance
of the power IC. This circuit do not work when the output is
from 0 to approx. 1Vrms. Then VCC is supplied from D709
only. When the output is more than 1Vrms, through D701D704, R722, D706, and Q703 is on, current is supplied
from Q702. When the output is over approx. 3Vrms, D709
is off, and VCC is supplied from Q702 only.
SPEAKER PROTECTION
1. When either terminal of BTL outputs connect with GND
(chassis) by mistake, the speaker protection circuit will
work as follows. through R707-R710, Q704 or Q705 is
on, and Q706 is on. Then #5Pin for Q701 is 0V, power IC
(Q701) will be in power off. Therefore, the product will be
STAND-BY status.
2. When the VCC CONTROL circuit is working correctly,
maximum current of R825 is 1A, and voltage between
R825 load is maximum 0.33V. When both terminals of BTL
outputs are shorted on outputting over 0.25W, R825 is
supplied over 2A, Q807 and Q803 is on, and the product
will be STAND-BY status.
2-7
CD 5V ON/OFF CONTROL
The voltage for CD (CD 5V) is supplied from QX04 when
the following conditions are satisfied fully. (for noise and
laser protection)
1. Setting a disc on the product, and QU08 is on.
2. Closing top panel, and #78Pin for QU10 is 0V.
3. The product is in CD mode.
MUTE CONTROL
Mute signals output from microprocessor (QU10) are
"MUTE (Pin No.37)", "MUTE2 (Pin No .7)", and "DSC MUTE
(Pin No.5)".
Fig.1 is workable output terminals by each mute signals,

TOP PANEL OPEN SENSOR
1. The pulse (T=84msec, Duty 50%) is always added to LED
(QU15), from #30Pin of QU10, through RF28 and QU22.
2. Cover the sensor with your fingers, the collector voltage
of QU01 goes up over 0.7VP-P. and through RU71 and
QU09, the pulse of 5VP-P inputs to #29Pin of QU10. Then
the top panel will open.
3. Not needing to cover the sensor with your fingers, QU01
receives the light of LED reflected by lens oneself.
Therefore, the collector of QU01 adds the reverse pulse
through RF29, QU26 and RF32, for reduced incorrect
working. So, the voltage of residual pulse for the collector
of QU01 is suppressed to 0.1VP-P.
REMARK
When the sensor receives sunlight or a strong light as
incandescent, top panel might open.

POPS NOISE KILLER
RX72, CX70 and QX70 are the circuit to delay power supply
for approx. 2 seconds. Therefore, this circuit prevents pops
noise generation when power switch is on or off.
SUB WOOFER
Sub woofer output is composed a low pass filter of cut-off
frequency 150Hz octave 12dB. It is output 2V for AUX L,R
input 60Hz, 200mV (volume is maximum).
REMARK
Sub woofer output level is depended on volume control.
3 SERVICE MODE
1. How to set the service mode
(1) While holding the CLOCK and CLEAR buttons together,
put the mains plug to mains outlet.
(2) FL check mode will start.
(3) While in FL check mode, each time the FUNCTION button
pressed (within 2 seconds), the mode changes in the
following order.
TR FREQ (Tracking point frequency memory mode) ➛

register in each preset memory.
REMARK
User programmed frequencies will be deleted.
While in Tracking point frequency memory mode, press the
MEMO button. Press the CLEAR and the DISPLAY buttons
together. The display shows “CLEAR” 2 seconds. Then all
memories will be clear.

the laser pick up unit stop beam out. All operations are
available without the Disc.
(3) While in CD test mode, CD play is available in opening
the top panel.
(4) If any ERROR is happened, the displa y shows “CD ERRX”.
(X is a ERROR code.) The ERROR message will not be
clear until pressing STOP or POWER buttons.
Error Code Description
1 The sledge switch not turn on.
