1. Before Repair and adjustment

Disconnect AC power, discharge Power Supply Capacitors C954 and C955 through a 10

, 5W resistor to ground. DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices. After repairsare completed, restore power gradually using a variac, to avoid overcurrent. Current consumption at AC230V, 50Hz in NO SIGNAL mode should be less than 220mA.

2. Protection Circuitry

The protection circuitry may have operated if either of the following conditions are noticed:

- No sound is heard when the power is turned on.

- Sound stops during a performance.

The function 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 ofthe amplifier are used. If this occurs, follow the procedure outlines below:

1. Turn off the power.

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

3. Turn on the power once again after one minute.

Note:

When the protection circuitry functions, the unit will not operate unless the power is first turned off and then on again.

4. Handling Precautions for Traverse Deck

The laser diodes in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body. So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup).

4.1. Handling the traverse deck (optical pickup)

1. The traverse deck (optical pickup) is an extremely high-precision construction and

must not be subjected to impact, excessive vibration, or other types of rough

handling.

2. In order to prevent static electricity damage to the laser diode, use a short pin or

similar tool to short the optical pickup’s flexible circuit boards after they have been disconnected from the main circuit board.

3. Handle the flexible circuit boards with care; excessive force could cause them to be

broken.

4. Do not turn the pre-set variable resistor (for adjustment of the laser power); it has

been adjusted at the factory. (as shown in Fig.1 )

Fig.1

4.2. Grounding for electrostatic breakdown prevention

1. Human body grounding

Use the anti-atatic wrist strap to discharge the static electricity from your body.

2. Work table grounding

Put a conductive material (sheet) or steel sheet on the area where the optical pickup is placed, and ground the sheet. (sa shown in Fig.2 )

Fig.2

Caution:

The static electricity of your clothes will not be grounded through the wrist strap. So, take care not to let your clothes touch the traverse deck (optical pickup)

4.3. Caution when Replacing the Traverse Deck

The traverse deck has a short point shorted with solder protect the laser diode against electrostatic breakbown. Be sure to remove the solder from the short point before making connections.

CAUTION:

THIS PRODUCT UNTILIZES A LASER. USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
