SERVICING NOTE

1) When repairing this device with the power on, if you remove

the main board or open the upper panel assy, this device stops

working.

In this case, you can work without the device stopping by

fastening the hook of the OPEN1 switch (S801) with tape.

2) This set is designed to perform automatic adjustment for each

adjustment and write its value to EEPROM. Therefore, when

EEPROM (IC803) has been replaced in service, be sure to per-

form automatic adjustment and write resultant values to the new

EEPROM.

Refer to page 12 for details.

SELF-DIAGNOSTIC

2) Remote controller LCD

2-1. GENERAL

This set uses the self-diagnostic system in which if an error occurs

in playback/recording mode, the error is detected by the model

control and power control blocks of the microprocessor and infor-

mation on the cause is stored as history in EEPROM.

By viewing this history in test mode, it helps you to analyze a fault

and determine its location.

There are two different methods to set the test mode:

1 Short BP801 (TEST) on the main board with a solder bridge

(connect pin @§ of IC801 to the ground). Then, turn on the

power.

This set provides the Overall adjustment mode (Assy mode) that

allows CD and MO disk to be automatically adjusted when in the

test mode. In this Assy mode, the system discriminates between

CD and MO disk and then automatically perform adjustments for

them in sequence. If a fault is found, the system displays its loca-

tion. Also, the Servo mode allows each individual adjustment to be

automatically adjusted.

6. ELECTRICAL PARTS LIST

NOTE:

• Due to standardization, replacements in

the parts list may be different from the

parts specified in the diagrams or the

components used on the set.

• -XX and -X mean standardized parts, so

they may have some difference from the

original one.

• Items marked “*” are not stocked since

they are seldom required for routine service.

Some delay should be anticipated

when ordering these items.

• SEMICONDUCTORS

In each case, u : µ, for example:

uA.. : µA.. uPA.. : µPA..

uPB.. : µPB.. uPC.. : µPC.. uPD.. : µPD..

• CAPACITORS

When indicating parts by reference

number, please include the board.

• RESISTORS

All resistors are in ohms.

METAL:Metal-film resistor.

METAL OXIDE: Metal oxide-film resistor.

F:nonflammable

uF : µF
