SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH

MARK 0 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 SUPPLEMENTS

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, through 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

1. POWER SUPPLY DURING REPAIRS

In this unit, about 10 seconds after power is supplied (8.4V) to the

battery terminal using the service power cord (J-6082-223-A), the

power is shut off so that the unit cannot operate.

This following two methods are av ailable to prev ent 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 remote commander switch to the

“ADJ” side.

Method 2.

Use the DC IN terminal. (Use the AC power adaptor.)

Pull the timing belt in the direction of

arrow

with a pincette while pressing

the cassette compartment (take care

not to damage) to adjust the bending

of a tape.

Let go your hold the cassette

compartment and rise the cassette

compartment to take out a cassette.

2. TO TAKE OUT A CASSETTE WHEN NOT EJECT (FORCE EJECT)

1 Refer to 2-1. to remove the front panel assembly.

2 Refer to 2-1. to remove the cabinet (R) assembly.

3 Refer to 2-1. to remove the battery panel assembly.

4 Refer to 2-1. to remove the cabinet (L) assembly.

5 Refer to 2-1. to remove the cassette lid assembly.

6 Disconnect CN974 of VC-234 board.

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

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 or Display

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 (CF-66/67 board BH001). When

this coin-type lithium battery is disconnected, 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 or Display window shows a 4-digit display consisting

of an alphabet and numbers, which blinks at 3.2 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 or PLAYER”, 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.
