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 .
ATTENTION AU COMPOSANT AYANT RAPPORT
À LA SÉCURITÉ!
LES COMPOSANTS IDENTIFÉS P AR UNE MARQUE 0 SUR LES
DIAGRAMMES SCHÉMA TIQUES 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.
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.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.

1-7-1. Self-diagnosis Function
When problems occur while the unit is operating, the self-diagnosis
function starts working, and displays on the viewfinder or LCD 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.
1-7-2. Self-diagnosis Display
When problems occur while the unit is operating, the counter of the
viewfinder or LCD 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.
1-7-3. Service Mode Display
The service mode display shows up to six self-diagnosis codes shown in the past.
1. Display Method
While pressing the “STOP” key, set the switch from OFF to “VCR”, 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.
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 [3] : Occurred third time [5] : Occurred fifth time
[2] : Occurred second time [4] : Occurred fourth time [6] : Occurred the last time
3. End of Display
Turning OFF the power supply will end the service mode display.

Self-diagnosis Code
Repaired by:
Correction
Inspect the lens block focus reset sensor (Pin qs of CN1551 of
VC-305 board) when focusing is performed when the control dial
is rotated in the focus manual mode and the focus motor drive circuit
(IC1554 of VC-305 board) when the focusing is not performed.
Inspect the lens block zoom reset sensor (Pin qg of CN1551 of
VC-305 board) when zooming is performed when the zoom switch
is operated and the zoom motor drive circuit (IC1554 of VC-305
board) when zooming is not performed.
Inspect pitch angular velocity sensor (SE751 of SI-035 board)
peripheral circuits.
Inspect yaw angular velocity sensor (SE752 of SI-035 board)
peripheral circuits.
