3-6. Adjust Specifications

[PW1 board (Side B)]

Note:
1. Voltage adjustment is necessary to repair in the PW1 board

and replace the parts.

2. Power voltage set about +3.0 V.
Preparation:
1. Connect CN104 on the CA2 board and CN502 on the PW1

board with extension cord.

2. Open the barrier switch.
3. Slide the slide switch to camera, and turn on the LCD.

1. IC501 Oscillation Frequency Adjustment

Adjustment method:
1. Adjust with VR501 to 200

1 kHz.

2. 5.0 V (D) Voltage Adjustment

Adjustment method:
1. Adjust with VR505 to 5.10

0.05 V.

3. 3.3 V (D) A Voltage Adjustment

Adjustment method:

1.Adjust with VR503 to 3.30

0.02 V

4. 3.4 V (D) B Voltage Adjustment

Adjustment method:
1. Adjust with VR504 to 3.40

0.03 V.

5. 12.4 V (L) Voltage Adjustment 1

Adjustment method:
1. Set the play mode.
2. Adjust with VR507 to 12.35

0.05 V.

6. 12.4 V (L) Voltage Adjustment 2

Adjustment method:
1. Set the view mode, and turn on the LCD.
2. Adjust with VR506 to 12.35

0.05 V.

[CA3 board (Side A)]

Note:
1. Voltage adjustment is necessary to repair in the CA3 board

and replace the parts.

2. Power voltage set about +3.0 V.
3. After adjustment, re-connect the flexible cable of the LCD

panel and CN171 as they were before.

Preparation:
1. Remove the sub-chassis to which the LCD panel is attached.

CN512 which is used for backlighting should always be left
still connected.

2. Open the barrier switch.
