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.
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.
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.

• NOT FOR REPAIR
Capacitor
Short jig
SERVICE NOTE
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.
When installing a connector, don't press down 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
capacitor 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-FD85/FD90 is simply turned off. Therefore,
the remaining voltage must be discharged as described below.
Preparing the Short Jig
To 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 circuits between the positive and the negative terminals of
charged capacitor with the short jig about 10 seconds.

Countermeasure
Change the disk and turn off the main
power then back on.
Replace the floppy disk.
Format the floppy disk with the MVCFD85/FD90.
Checking of flash unit or replacement of
flash unit
Checking of lens drive circuit
Cause
Defective floppy disk.
• The type of floppy disk that cannot be
used by this machine, is inserted.
(Such as 2DD)
• Data is damaged.
• Unformatted disk is inserted.
