2-2. REPAIR 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 levers. (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.
2-3. EXPLANATION 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 over 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.
2-7
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 fan 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 primar y 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. 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, Fig.2 is the status of each mute.

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.

Use service test program. By selecting the TUNER TEST test frequencies will be stored as preset frequencies automatically.
1) If sensitivity of frequency counter is too low adjust to max. channel separation 2) RC network serves for damping the IF-filter while adjusting the other one. 4) MW has to be aligned before LW.
