TROUBLESHOOTING

No Display

1. Check the fuse (FU500) on the digital PCB.

2. Check the fuse (FU100) on the linear PCB.

3. Check the jack (JK500) on the digital PCB.

4. Check the power switch (SW900) on the key PCB.

5. Check the flat cable between the digital and linear PCBs.

6. Check the back light.

7. Check the LCD.

No Display at Record Mode

1. Check the camera unit.

Defect of the Camera Unit

The camera unit must be replaced with whole unit when it is defective, because the precise adjustment is

required when the individual parts of the camera unit are replaced, and it can be done only at our factory.

(Except for replacing the outer case of the camera unit)
