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, par-ticularly tran-
sistors, 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 replace-ment.
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 dur-
ing 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 solder-
ing or unsoldering.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.

[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 1k
/1W (1-215-869-11)
Wrap insulating tape fully around the leads of the resistor to pre-
vent electrical shock.
1k
/1W
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
[LCD type judging method]
The LCD type can be judged by measuring resistance between 4
pin and !¢ pin of CPC-9 jig.

[How to connect the extension cable]
1) Remove the PK-43 board and the liquid crystal indication
module. (See page 2-2E.)
Note : Be careful not to breake the flexible board of the floppy disk drive.
2) Install the Extension cable (J-6082-427-A) on the rear cabi-
net. (See Fig. 1.)
3) Install the floppy disk drive. (See Fig. 2.)
4) Open the lithium lid. (See Fig. 3.)
5) Mount the flexible board on CN013. (See Fig. 3.)
6) Install the PK-43 board. (See Fig. 4.)
Note : The floppy disk drive and PK-43 board could be destroyed unless
the flexible board is connected normally to the connector.
