1. Turn off the power supply. Using a 10, 10 W resistor, connect both ends of power supply
capacitors (C701, C702) in order to discharge the voltage.
2. Before turning the power supply on, after completion of repair, slowly apply the primary
voltage by using a power supply voltage controller to make sure that the consumed current at
50 Hz in NO SIGNAL mode should be shown below with respectto supply voltage 230/240 V.
Power supply AC 230 V, 50 AC 240 V, 50
voltage Hz Hz
Consumed current 70-270 mA 60-260 mA

2 Protection Circuitry
TOP PREVIOUS NEXT
The protection circuitry may have operated if either of the following conditions is noticed:
No sound is heard when the power is switched ON.
Sound stops during a performance.
The functions 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 this unit are used.
If this occurs, follow the procedure outlined bellow:
1. Switch OFF the power.
2. Determine the cause of the problem and correct it.
3. Switch ON the power once again.
Note:
When the protection circuitry functions, the unit will not operate unless the power is first switched
OFF and ON again.

7 About the+/- 15 V Line Abnormality Detect
Function
TOP PREVIOUS NEXT
1. This model features the function that shuts down the main power source when it check the± 15
V line with the IC801 (microcomputer) and find the different voltage. (After power is turned
on, the unit enters the stand-by mode.)
2. When the unit enters stand-by mode with abnormality detected, check the circuits around the±
15 V line. (Specially check the abnormality of the stabilizing power source circuit.)
3. To clear this stand-by mode, short-circuit the TP801 land on the circuit board. However,
clearance of the stand-by mode and turn on the electricity when the repair is not completed
may lead to another trouble. Therefore, be especially carefulto do so. (Do not turn on the
electricity for a long time.)
4. When the repair is completed, leave the TP801 open.

7.1 About the abnormality detect function with
the operation LED turned off
TOP PREVIOUS NEXT
1. If the operation LED is turned off, there are possibilities of the following abnormalities in
addition to the LED itself malfunctioning:
2. Power amplifier´s malfunction by the speaker terminal short-circuit.
3. Malfunction of cooling fan.
The unit features the function that detects above abnormalities.

Indicated voltage values are the standard values for the unit measured by the DC electronic circuit
tester (high-impedance) with the chassis taken as standard. Therefore, there may exist some errors in
the voltage values, depending on theinternal impedance of the DC circuit tester.

Important safety notice:
Components identified by mark have special characteristics important for safety.
Furthermore, special parts which have purposes of fire-retardant (resistors), high-quality sound
(capacitors), low-noise (resistors), etc. are used.
When replacing any of components, be sure to use only manufacturers specified parts shown in the
parts list.
Caution!
IC and LSI are sensitive to static electricity.
Secondary trouble can be prevented by taking care during repair.
Cover the parts boxes made of plastics with aluminum foil.
Ground the soldering iron.
Put a conductive mat on the work table.
Do not touch the legs of IC or LSI with the fingers directly.
