12. Pictures cannot be taken.
Is the camera (CA100) installed in the right direction?
Reinsert the camera (CA100).
Check that IC603 has not come off.
Is there conduction between TP604 and TP606?
IC603 is mounted improperly.
Are all the pins of SO601 mounted properly?
SO601 is mounted improperly.
Replace the camera (CA100). Does the camera turn on?
The camera (CA100) is defective.
(Most likely poor contact caused by adhesive on pins)

on)?
Is 2.8 V applied to TP601?
Short terminal (TP601 to SO601 pin 23) and (TP601 to
SO601 pin 5) are defective.
IC603/IC106 is defective, or R602/C607 is mounted improp-
erly.
SO601:
1. Is 2.8 V applied on pins 4 and 7?
2. Is the voltage 0 V on pin 8?
3. Is the 13 MHz frequency sent to pin 1?
(when camera is on)
IC603 peripheral circuits:
1. Is 13 MHz frequency sent to R602?
2. Is 2.93 V applied to C607?
(when camera is on)
Is 1.8 V applied to IC603 peripheral circuit TP607 (when cam-
era is on)?
IC601 or peripheral circuits
are defective; R605/C609 is
mounted improperly.
Is 2.93 V applied to IC603 peripheral circuit R604
(when camera is on)?
IC103 or peripheral circuits
are defective; R604/C608 is
mounted improperly.
IC603 or IC106 is defective.
R606 and C610 are mounted improperly.
R606 is defective.
SO601:
1. Is 2.8 V applied on pins 2 and 3 (when camera is on)?
2. Are voltages of pins 2 and 3 within the range 0 to 2.8 V
(when camera being activated)?
Is 2.8 V applied to IC603 peripheral circuit R606
(when camera is on)?
IC603 is defective.
