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.

Use the AC power adaptor (AC-L10, AC-VQ800, AC-SQ950 etc.).

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

1

Refer to 2-2. to remove the HS cover.

2

Refer to 2-2. to remove the jack cover.

3

Refer to 2-2. to remove the cabinet (R) assembly.

4

Refer to “3. DISCHARGING OF THE FLASHLIGHT POWER SUPPLY CAPACITOR” to discharge the flash power supply capacitor.

5

Refer to 2-3. to remove the mechanism deck and the lens block and the EVF block from the cabinet (L) block.

6

Disconnect CN302 (72P, 0.4mm) of VC-270 board.

7

Disconnect CN006 (27P, 0.3mm) of VC-270 board.

8

Supply +4.5V from the DC power supply to the loading motor and unload with a pressing the cassette compartment.

The capacitor (C2010) of the flash unit (MC1850) is charged up to the maximum 300V potential. There is a danger of electric shock by this
high voltage when the flash unit (MC1850 or ST1850) 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.

To preparing the short jig. a small clip is attached to each end of a resistor of 1k

Ω

/1W (1-215-869-11). Wrap insulating tape fully around the

reads of the resistor to prevent electric shock.

Connect the short jig with the capacitor directly.
1

Remove the power supply (Battery or AC power adaptor).

2

Short circuit between TP001 of the flash unit (MC1850) and the GND
(Chassis etc.) with the short jig about 10 seconds.

Perfect discharge can’t be done in this method. (Remaining voltage = Approx. 90V)

1

Connect the power supply (Battery or AC power adaptor).

2

Set POWER switch to “CAMERA”.

3

Connect the adjustment remote commander to the LANC jack, and set the HOLD switch to the “ADJ” side.

4

Select page: 0, address: 01. and set data: 01.

5

Select page: D, address: F4. set data: 04, and press PAUSE button of the adjustment remote commander.

6

Press FLASH (   ) button and set to the forced flash mode (   ), and press PHOTO button to pop up the flash.

Repeat step 9, until the flash dose not flash.
After completing repairs/adjustments, perform “PROCESSING AFTER COMPLETING REPAIRS/ADJUSTMENTS”

1

Connect the power supply (Battery or AC power adaptor).

2

Set POWER switch to “CAMERA”.

3

Connect the adjustment remote commander to the LANC jack, and set the HOLD switch to the “ADJ” side.
