Symptom/State

Non-standard battery is used.

Faulty disc is used.

Disc access error

Condensation.

Codec IC dose not return any reply

EEPROM data are rewritten.

Drive fault

Codec IC fault

Audio Codec IC fault

Difficult to adjust focus
(Cannot initialize focus.)

Zoom operations fault
(Cannot initialize zoom lens.)

The abnormalities in initialization of
the focus lens and the abnormalities in
initialization of the zoom lens occurred
simultaneously.

Handshake correction function does not
work well. (With PITCH angular
velocity sensor output stopped.)

Handshake correction function does not
work well. (With YAW angular velocity
sensor output stopped.)

Abnormality when flash is being charged.

Fault of writing to or erasing the
flashmemory

Fault of writing to or erasing EEPROM

Correction

Use the InfoLITHIUM battery.

Remove the power source. Reconnect it again and operate your
camcorder again

Remove the power source. Reconnect it again and operate your
camcorder again

Remove the disc, and insert it again after one hour.

Remove the power source. Reconnect it again and operate your
camcorder again

Make EEPROM data correct value. (Note 1)

Inspect or replacement of the hand disc drive

Inspect or replacement of the codec IC (IC2301on the VC-449
board) peripheral circuits

Inspect or replacement of the Audio Codec IC (IC2301 on the
VC-449 board) peripheral circuits

Inspect the lens block focus MR sensor (pin ql, wa of CN1701
on the VC-449 board) when focusing is performed when the
focus buttons of the touch panel are pressed in the focus manual
mode, and the focus motor drive circuit (IC1701 on the VC-449
board) when the focusing is not performed.

Inspect the lens block zoom MR sensor (pin ws, wf of CN1701
on the VC-449 board) when zooming is performed when the
zoom lever is operated, and the zoom motor drive circuit
(IC1701 on the VC-449 board) when zooming is not performed.

Check whether the flexible board of the lens is broken, and
check whether it is inserted imperfectly. If there is no problem in
the  flexible board, inspect the focus/zoom motor drive circuit
(IC1701 on the VC-449 board).

Inspect PITCH angular velocity sensors (SE7104 on the IR-057
board) peripheral circuits.

Inspect YAW angular velocity sensors (SE7103 on the IR-057
board) peripheral circuits.

Checking of flash unit or replacement of flash unit. (Note 2)

Inspect the flash memory (IC2401 on the VC-449 board). (Note 1)

Inspect the EEPROM (IC2602 on the VC-449 board). (Note 1)

Note 1: Refer to “ 12-2. Record of Self-diagnosis check” of “2-5. SERVICE MODE”, ADJ (9-876-940-51).
Note 2: After repair, be sure to perform “1-4. PROCESS AFTER FIXING FLASH ERROR”.
