1. Check the area of your repair for unsoldered or poorly-sol-
dered 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 transis-
tors, that were installed during a previous repair. Point them
out to the customer and recommend their replacement.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.
4. Look for parts which, though functioning, show obvious signs
of deterioration. Point them out to the customer and recom-
mend 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.

[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 re-
maining 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 k
/1 W (1-215-869-11).
Wrap insulating tape fully around the leads of the resistor to pre-
vent electrical shock.
1 k
/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.
SERVICE NOTE
· 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.
When remove a connector, don't pull at wire of connector.
Be in danger of the snapping of a wire.
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 installing a connector, don't press down at wire of connector.
Be in danger of the snapping of a wire.
