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.
SAFETY CHECK-OUT
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.
ATTENTION AU COMPOSANT AYANT RAPPORT
À LA SÉCURITÉ!
LES COMPOSANTS IDENTIFIÉS P AR 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 PIÈCES SONY DONT LES
NUMÉROS SONT DONNÉS DANS CE MANUEL OU
DANS LES SUPPLÉMENTS PUBLIÉS PAR SONY.
4. Look for parts which, though 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 sol-
dering or unsoldering.

SERVICE NOTE
When installing a connector, don’t press down at wire of connector.
Be in danger of the snapping of a wire.
• NOTE FOR REPAIR
Make sure that the flat cable and flexible board are not cracked of
bent at the terminal.
Do not insert the cable insufficiently nor crookedly.
Cut and remove the part of gilt
which comes off at the point.
(Take care that there are some
pieces of gilt left inside)
When remove a connector, don’t pull at wire of connector.
Be in danger of the snapping of a wire.
[Discharging of the FLASH unit’s charging capacitor]
The charging capacitor of the FLASH unit is charged up to the
maximum 300 V potential.
There is a danger of electric shock by this high voltage when the
battery is handled by hand. The electric shock is caused by the
charged voltage which is kept without discharging when the main
power of the MVC-FD71 is simply turned off. Therefore, the remaining voltage must be discharged as described below.
Preparing the Short Jig
T o preparing the short jig. a small clip is attached to each end of a
resistor of 1 kΩ /1 W (1-215-869-11).
Wrap insulating tape fully around the leads of the resistor to prevent electrical shock.
1 kΩ/1 W
Wrap insulating tape.
Discharging the Capacitor
Short-circuit between the positive and the negative terminals of
charged capacitor with the short jig about 10 seconds.
