CAUTION
Use of controls or adjustments or performance
procedures other than those specified herein may
result in hazardous radiation exposure.
WARNING!!
WHEN SERVICING, DO NOT APPROACH THE LASER
EXIT WITH THE EYE TOO CLOSELY. IN CASE IT IS
NECESSARY TO CONFIRM LASER BEAM EMISSION,
BE SURE TO OBSERVE FROM A DISTANCE OF MORE
THAN 30 cm FROM THE SURFACE OF THE
OBJECTIVE LENS ON THE OPTICAL PICK-UP BLOCK.
CAUTION :
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type.
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.
CAUTION:
The use of optical instrument with this product will increase eye
hazard.
ATTENTION AU COMPOSANT AYANT RAPPORT
À LA SÉCURITÉ!
LES COMPOSANTS IDENTIFÉS PAR UNE MARQUE 0 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.
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.
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
Unleaded solder
Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size.)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40°C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350°C.
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow) than
ordinary solder so use caution not to let solder bridges occur such
as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

SERVICE NOTE
1-1. SERVICE NOTE
1.POWER SUPPLY DURING REPAIRS
In this unit, about 10 seconds after power is supplied to the battery terminal using the regulated power supply (8.4V), the po wer is shut of f 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.
Use the AC power adaptor (AC-L15, AC-VQ800 etc.).
Method 2.
Connect the servicing remote commander RM-95 (J-6082-053-B) to the LANC jack, and set the commander switch to the “ADJ” side.
2.TO TAKE OUT A CASSETTE WHEN NOT EJECT (FORCE EJECT)
1 Refer to page 2-2 to remove the front panel assembly.
2 Refer to page 2-3 to remove the cabinet (R) assembly.
3 Refer to page 2-10 to remove the battery panel section.
4 Refer to page 2-11 to remove the EVF block.
5 Remove the VC-307 board.
6 Refer to page 2-15 to remove the lens block and the accessory shoe.

3.NOTES ON HANDLING THE OPTICAL PICK-UP
The laser diode may suffer electrostatic breakdown because of the
potential difference generated by the charged electrostatic load, etc.
on clothing and the human body.
During repair, pay attention to electrostatic breakdown and also use
the procedure in the printed matter which is included in the repair
parts.
The flexible board is easily damaged and should be handled with
care.

4.PRECAUTION FOR CHECKING EMISSION OF
LASER DIODE
Laser light of the equipment is focused by the object lens in the
optical pick-up so that the light focuses on the reflection surface of
the disc. Therefore, be sure to keep your eyes more then 30 cm
apart from the object lens when you check the emission of laser
diode.

1.SELF-DIAGNOSIS FUNCTION
When problems occur while the unit is operating, the self-diagnosis
function starts working, and displays on the viewfinder, or LCD
screen what to do. This function consists of two display; selfdiagnosis display and service mode display .
Details of the self-diagnosis functions are provided in the Instruction
manual.
Viewfinder or LCD screen
C : 3 1 : 1 1
Blinks at 3.2Hz
2.SELF-DIAGNOSIS DISPLAY
When problems occur while the unit is operating, the counter of the
viewfinder or LCD screen consists of an alphabet and 4-digit number ,
which blinks at 3.2Hz. This 5-character display indicates the
“repaired by:”, “block” in which the problem occurred, and “detailed
code” of the problem.

Make EEPROM data correct value. (Note)
Inspect the lens block focus reset sensor (Pin 7 of CN1201 of VC-
307 board) when focusing is performed when the control dial is rotated
in the focus manual mode and inspect the focus motor drive circuit
(IC1203 of VC-307 board) when the focusing is not performed.
Inspect the lens block zoom reset sensor (Pin qh of CN1501 of
VC-307 board) when zooming is performed when the zoom switch
is pressed and inspect the zoom motor drive circuit (IC1203 of
VC-307 board) when the zooming is not performed.
