SAFETY-RELATED COMPONENTWARNING!!

COMPONENTS IDENTIFIED BY MARK !OR DOTTED LINEWITH

MARK !ON THE SCHEMATIC DIAGRAMS AND INTHE PARTS

LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE

COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS

APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS

PUBLISHED BY SONY.

ATTENTION AU COMPOSANT AYANT RAPPORT

À LA SÉCURITÉ!

LES COMPOSANTS IDENTIFÉS 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 PIÈSES SONY

DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU

DANS LES SUPPÉMENTS PUBLIÉS PAR SONY.

1. Check the areaof yourrepairfor unsoldered orpoorly-soldered

connections. Checkthe entire boardsurfaceforsolder 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, through functioning, showobvious 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.

1. POWER SUPPLY DURING REPAIRS

In this unit, about 10 seconds after power is supplied to the battery

terminal using the regulated power supply (8.4 V), the power is

shut off so that the unit cannot operate.

This following two methods are available to prevent this. Take note

of which to use during repairs.

Method 1.

Connect the servicing remote commander RM-95 (J-6082-053-B)

to the LANC jack, and set the commander switch to the “ADJ”

side.

Method 2.

Use the DC IN terminal. (Use theAC power adaptor (AC-L10,AC-

VQ800 etc. ))

2. TOTAKE OUT A CASSETTE WHEN

NOT EJECT (FORCE EJECT)

1Refer to 2-2 to remove the shoe cover.

2Refer to 2-3. to remove the cabinet (L) assembly.

3Refer to 2-3. to remove the mechanism deck.

4Disconnect from CN2303 (4P, 0.8mm) of MR-44 board.

5Add +4.5V from the DC POWER SUPPLY and unload with a

pressing the cassette compartment.

SELF-DIAGNOSIS FUNCTION

1. SELF-DIAGNOSIS FUNCTION

When problems occur while the unit is operating, the self-diagnosis

function starts working, and displays on the viewfinder, LCD screen

or LCD window what to do. This function consists of two display;

self-diagnosis display and service mode display.

Details of the self-diagnosis functions are provided in the Instruction

manual.

Note: The “self-diagnosis display” data will be backed up by the coin-type lithium battery (BT1050) of the control switch block (FK-4950). When the

control switch block is removed, the “self-diagnosis display” data will be lost by initialization.

2. SELF-DIAGNOSIS DISPLAY

When problems occur while the unit is operating, the counter of the

viewfinder, LCD screen or LCD window consists of an alphabet

and 4-digit numbers, which blinks at3.2 Hz. This 5-character display

indicates the “repaired by:”, “block” in which the problem occurred,

and “detailed code” of the problem.

3. SERVICE MODE DISPLAY

The service mode display shows up to six self-diagnosis codes shown in the past.

3-1. Display Method

While pressing the “STOP” key, set the switch from OFF to “VTR”, and continue pressing the “STOP” key for 5 seconds continuously. The

service mode will be displayed, and the counter will show the backup No. and the 5-character self-diagnosis codes.

3-2. Switching of Backup No.

By rotating the control dial, past self-diagnosis codes will be shown in order. The backup No. in the [] indicates the order in which the

problem occurred. (If the number of problems which occurred is less than 6, only the number of problems which occurred will be shown.)

[1] : Occurred first time [4] : Occurred fourth time

[2] : Occurred second time [5] : Occurred fifth time

[3] : Occurred third time [6] : Occurred the last time

3-3. End of Display

Turning OFF the power supply will end the service mode display.
