Checkpoints
Solution
1
Is the user trying to take a picture
within 80cm to the subject without
using Macro mode?
Advise the user to use Macro
mode.
2
Are 3 fixing screws for lens viewfinder
unit and lens unit removed?
(Removing these 3 screws is
prohibited)
Replace the whole lens unit.
3
Is the CCD soldering on the CA1 board
performed correctly? Especially, the
lens unit determines the position when
soldering, perform soldering by
covering the lens unit without soldering
only the CCD.
Re-solder the CCD correctly.
C A U T I O N
Camera may work fine even when the CCD is broken
and unable to read images. From the repairing
experiences of PhotoPC 500, main control board
(corresponding to CA2 board in case of PhotoPC-
750Z) is found defective from the abnormal symptoms
related to CCD. Even when the LCD monitor is not all
black but if red or green are strong, there is a high
possibility that AWB adjustment values are abnormal.
No.
Checkpoints
Solution
1
Is CA2 board defective?
Replace the CA2 board.
2
Is CA1 board defective?
Replace the CA1 board.
3

If color is obviously abnormal, perform 5100K AWB adjustment again. At
this time, follow the cautions below when using the Color Viewer.
*Avoid entering any lights. *Keep the distance between the Color Viewer
and lens within 1cm. (It is OK to let them attach each other) *Set the
volume of Color Viewer to the maximum, and wait about 10 minutes after
turning the Color Viewer On in order to settle the brightness.
