1. Before Repair

1. Turn off the power supply. Using a10 , 10 Wresistor, connect

both ends of power supplycapacitors (C701, C702) inorder to

discharge the voltage.

2. Before turning the power supplyon, after completion of repair,

slowlyapplythe primaryvoltage byusing apower supplyvoltage

controller to make sure that the consumed current at 50 HzinNO

SIGNALmode shouldbe shownbelow with respect to supply

voltage 230/240 V.

Powersupply

voltage AC 230 V, 50 Hz AC 240 V, 50 Hz

Consumed

current 70-270 mA 60-260 mA

2. Protection Circuitry

The protection circuitrymayhave operatedif eitherof the following conditions is noticed:

-Nosound isheard when the power isswitched ON.

-Sound stops during aperformance.

The functions of this circuitryis toprevent circuitrydamage if, forexample, the positive and

negative speakerconnection wires are shorted, orif speakersystems withanimpedance less

thanthe indicatedratedimpedance of this unit are used.

If this occurs, followthe procedure outlinedbellow:

1. Switch OFF the power.

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

3. Switch ONthe power once again.

Note:

When the protection circuitryfunctions, the unitwill not operate

unless the power isfirst switched OFF and ONagain.

3. Accessories

5. Operations

6. Operation Checks and Component Replacement /

Procedures

7. About the +/- 15 V Line Abnormality Detect

Function

1. Thismodel features the function that shuts downthe mainpower

source when itcheck the ± 15 Vline with the IC801

(microcomputer) and find the different voltage. (After power is

turned on, the unitenters the stand-bymode.)

2. When the unitenters stand-bymode with abnormalitydetected,

check the circuits arround the ± 15 Vline. (Speciallycheck the

abnormalityof the stabilizing power source circuit.)

3. To clear thisstand-bymode, short-circuitthe TP801 land on the

circuitboard. However, clearance of the stand-bymode and turn

on the electricitywhen the repairisnot completed maylead to

another trouble. Therefore, be especiallycareful to do so. (Donot

turn on the electricityfor along time.)

4. When the repairiscompleted, leave the TP801 open.

7.1. About the abnormalitydetect function with the operation LED

turned off

1. Ifthe operation LEDisturned off, there are possibilities of the

following abnormalities inaddition to the LEDitselfmalfunctioning

-Power amplifier´s malfunction bythe speaker terminal short-

circuit.

-Malfunction of cooling fan.

The unitfeatures the function that detects above abnormalities.
