EVR Data Re-writing Procedure When Replacing Board

The data that is stored in the repair board, is not necessarily correct. Perform either procedure 1 or procedure 2 or procedure 3 when replacing board.

Procedure 1

Save the EVR data of the machine in which a board is going to be replaced. Download the saved data after a board is replaced.

DSC-F77/FX77

SECTION 6

ADJUSTMENTS

(Machine before starting repair)

Save the EVR data to a personal computer.

Procedure 2

Remove the EEPROM from the board of the machine tha t is going to be repaired. Install the removed EEPR OM to the replaced board.

PC PC

Remove the EEPROM and install it.

(Former board)

(New board)

(Machine after a board is replaced)

Download the saved data to a machine.

Procedure 3

When the data cannot be saved due to defective EEPROM, or when the EEPROM cannot be removed or installed, save the data from the same model of the same destination, and download it.

(Machine to be repaired)

Download the data.

Save the data.

(The same model of the same destination)

After the EVR data is saved and downloaded, check the respective items of the EVR data. (Refer to page 6-2 for the items to be checked.)

to “2. DISASSEMBLY”.

Note 2: When performing only the adjustments, the lens block

and boards need not be disassemble.

1) Connect the equipment for adjustments according to Fig. 6-1-

2) Connect the adjusting remote commander to cradle with LANC jack (J-6082-548-A).

Note 3: Setting the “Forced CAMERA mode power ON Mode”

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

2) Select page: D, address: 21, set data: 04, and press the PAUSE button of the adjusting remote commander. The above procedure will enable the camera power to be turned on. After completing adjustments, be sure to exit the “Forced CAMERA mode power ON Mode”.

1-1-3. Discharging of the Flashlight Power Supply

The capacitor which is used as power supply of flashlight is charged with 200 V to 300 V voltage. Discharge this voltage before starting adjustments in order to protect service engineers from electric shock during adjustment.

Discharge procedure

1. Press the FLASH button (SY -81 board S855 (CONTR OL UP)) and set the NO FLASH mode.

2. Fabricate the discharging jig as shown in Fig. 6-1-4 locally by yourself. Connect the discharging jig to the positive (+) and negative (–) terminal of the flash voltag e charge capacitor . Allow ten seconds to discharge the voltage.
