1. Check the areaof your repair for unsoldered or poorly-soldered

connections. Checkthe entire boardsurfacefor 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 partswhich, through functioning, showobvioussigns

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 lead-

free 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.

2. POWER SUPPLY DURING REPAIRS

In this unit, about 10 seconds after power is supplied to the battery terminal using the regulated power supply (8.4V), the power is shut off so

that the unit cannot operate.

This following two methods are available to prevent this. Take note of which to use during repairs.

Method 1.

Use the AC power adaptor.

Method 2.

Connect the servicing remote commander RM-95 (J-6082-053-B) to the LANC jack, and set the commander switch to the “ADJ”side.

3. TOTAKE OUT A CASSETTE WHEN NOT EJECT (FORCE EJECT)

4. DISCHARGING OFTHE FLASHLIGHT POWER SUPPLY CAPACITOR

The power supply capacitor (ST-106 board C5605) of the flash unit is charged up to the maximum 300V 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 unit is simply turned off. Therefore, the remaining voltage must be

discharged as described below.

4-1. PREPARINGTHE SHORT JIG

To preparing the short jig. a small clip is attached to each end of a resistor of 1kΩ/1W (1-215-869-11).

Wrap insulating tape fully around the reads of the resistor to prevent electric shock.

4-2. DISCHARGINGTHE CAPACITOR

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

screen what to do. This function consists of two display; self-

diagnosis display and service mode display.

Detailsof the self-diagnosis functions areprovidedin the Instruction

manual.

2. SELF-DIAGNOSIS DISPLAY

When problems occur while the unit is operating, the counter of the

viewfinderorLCD screen consists ofan alphabet and 4-digitnumber,

which blinks at 3.2Hz. This 5-character display indicates the

“repairedby:”,“block”inwhich the problemoccurred, and “detailed
