ATTENTION AU COMPOSANT AYANT RAPPORT

À LA SÉCURITÉ!!

LES COMPOSANTS IDENTIFIÉS PAR UNE MARQUE !SUR

LES DIAGRAMMES SCHÉMATIQUES ET LA LISTE DES

PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ DE

FONCTIONNEMENT. NE REMPLACER CES COMPOSANTS

QUE PAR DES PIÈCES SONY DONT LES NUMÉROS SONT

DONNÉS DANS CE MANUEL OU DANS LES SUPPLÉMENTS

PUBLIÉS PAR SONY.

SAFETY-RELATED COMPONENT WARNING !!

COMPONENTS IDENTIFIED BY MARK !OR DOTTED LINE

WITH MARK !ON THE SCHEMATIC DIAGRAMS AND IN THE

PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE

THESE COMPONENTS WITH SONY PARTS WHOSE PART

NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUP-

PLEMENTS PUBLISHED BY SONY.

1. Check the area of your repair for unsoldered or poorly-soldered

connections. Check the entire board surface for solder splashes

and bridges.

2. Check the interboard wiring to ensure that no wires are

“pinched” or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularly

transistors, that were installed during a previous repair. Point

them out to the customer and recommend their replacement.

4. Look for parts which, though functioning, show obvious signs

of deterioration. Point them out to the customer and

recommend their replacement.

5. Check the B+ voltage to see it is at the values specified.

6. Flexible Circuit board Repairing

• Keep the temperature of the soldering iron around 270°C

during repairing.

• Do not touch the soldering iron on the same conductor of

the circuit board (within 3 times).

• Be careful not to apply force on the conductor when

soldering or unsoldering.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following

safety checks before releasing the set to the customer:

SERVICE NOTE

1Ejecting with the cabinet (L) assembly removed

• Refer to “2. DISASSEMBLY”, and supply power with the

cabinet (L) assembly removed (however leave the flexible board

connecting the cabinet (L) assembly and main unit connected).

• Ejecting:

Operate the CS bracket assembly, open the cassette lid, turn

OFF the CC DOWN SW, and press the Eject button again.

• Loading:

Close the cassette lid.

(Turn ON the CC DOWN SW)

2Handling the VC. MR board

Never heat the VC and MR boards with hot air. (Malfunctions

may result.)

Also remove after dehumidifying.

3Special precautions on disconnection of connector

attached to the flexible board

• Apply force in the arrow direction and disconnect.

• Do not apply force in the direction as this will cause the solder

(of the pin) to float easily.

• When touching the pins with the solder iron, do not touch other

parts. (deformation may occur.)

• Ensure no folding lines are formed on the flexible board.

(This will cause the internal copper film to cut easily.)

Slide the CS lock plate in the arrow

direction, and open the cassette lid.
