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 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 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.
• SUPPLIED ACCESSORIES
Check that the following accessories are supplied with your
camcorder.

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 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 remote commander switch to the
“ADJ” side.
Method 2.
Press the battery switch of the battery terminal using adhesive tape,
etc.
Method 3.
Use the AC power adaptor.
2. HOW TO TAKE A CASSETTE OUT
WHEN THE MAIN POWER CANNOT
BE TURNED ON
Note: To take a cassette out forcibly as follows when the main power
cannot be turned on, remove the cassette lid, cabinet (L) and cabinet
(R). Apply +4.5 V power from an external power supply to the
loading motor, as shown below. Refer to sections 2-1 and 2-2 for
the procedure to remove the cabinet (L) assembly.
Procedure:
1) Disconnect the CN2913 of VI-151 board.
2) Apply +4.5 V directly to the loading motor as shown to drive
the loading motor that ejects a cassette.
Loading motor
DC power supply (+4.5V)
Disconnect CN2913
of VI-151 board.

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 of CK-80 board BT7200. When this coin-type lithium battery
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 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.
