1. Turn off the power supply. Using a 10Ω, 10 W resistor, connect both ends of power supply

capacitors (C701, C703 and C702, C704) 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 voltage AC 230 V AC 240 V

Consumed current 50 Hz 70 ~ 250 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 system with an impedance less than the indicated

rated impedance of this unit are used.

If this occurs, follow the procedure outlined below.

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 then ON again.
