In this unit, about 10 seconds after power is supplied to the battery terminal using the regulated power supply (8.4V), the power is shut off so
that the unit cannot operate.
These following method is available to prevent this.

Use the AC power adaptor (AC-L200).

1

Remova the screw (M1.7) and front cover (227)

2

Insert the wire etc. in the hole.

1-3-1. Be sure to perform “DESTINATION DATA WRITE” after replacing VC-478 board.

Please refer to the “Aut-ADJ” manual (9-852-179-5s).

1-3-2. Be sure to perform “USB SERIAL No. INPUT” after replacing VC-478 board.

Please refer to the “Aut-ADJ” manual (9-852-179-5s).

1. Connect the extension cable (J-6082-656-A) between CN4006 on the MD-134 board and CN1005 on the VC-478 board.

When problems occur while the unit is operating, the self-diagnosis
function starts working, and displays on the viewfinder or LCD
screen what to do. This function consists of two display; self-
diagnosis display and service mode display.
Details of the self-diagnosis functions are provided in the Instruction
manual.

When problems occur while the unit is operating, the counter of the
viewfinder or LCD screen shows a 4-digit display consisting of an
alphabet and numbers, which blinks at 3.2 Hz. This 5-character
display indicates the “repaired by:”, “block” in which the problem
occurred, and “detailed code” of the problem.

Faulty disc is used.

Disc access error

Codec IC dose not return any reply

Difficult to adjust focus
(Cannot initialize focus)

EEPROM data are rewritten.

Drive fault

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 of IC for steadyshot.

IC for steadyshot and micro controller
communication abnormality among.

Shift lens initializing failure.

Abnormality of thermistor.

Abnormality when flash is being charged.

Fault of writing to or erasing the
flashmemory

Self-diagnosis Code

Repaired by:

Correction

Use the InfoLITHIUM battery.

Use a compatible disc with the camcorder.

Clean the disc with the supplied cleaning cloth.
Use a compatible disc with the camcorder.

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

Retry turn the power on by the power switch. If it does not
recover, check the focus MR sensor of lens block (pin ql, wa of
CN5302 on the LD-215 board) (Note1), (pin qh, qk of CN5302
on the LD-216 board) (Note2).  If it is OK, check the focus
motor drive IC (IC5404 on the LD-215 board) (Note1), (IC5404
on the LD-216 board) (Note2) .

Make EEPROM data correct value.

Inspect or replacement of the mechanism deck, IC (IC4201 on
the MD-134 board) and drive block

Inspect the lens block zoom MR sensor  (pin qh, qk of CN5302
on the LD-215 board) (Note1), (pin w;, wa of CN5302 on the
LD-216 board) (Note2). when zooming is performed when the
zoom lever is operated, and the zoom motor drive circuit
(IC5404 on the LD-215 board) (Note1), (IC5404 on the LD-216
board) (Note2) when zooming is not performed.

Check both C: 32: 60 and E: 61: 10 of the self-diagnosis code.

Inspect PITCH angular velocity sensors (SE8202 on the CM-076
board) (Note1), (SE7202 on the CM-077 board) (Note2)
peripheral circuits.

Inspect YAW angular velocity sensors (SE8201 on the CM-076
board) (Note1), (SE7201 on the CM-077 board) (Note2)
peripheral circuits.

Refer to [1-6-1. E : 62 : 02 (Abnormality of IC for Steadyshot)
Occurred] (Note 2).

Inspect the steadyshot circuit (IC5703 on the LD-216 board)
(Note 2).

Note 2:
1. Inspect the EEPROM (IC1840 on the VC- 478).
2. Perform the STEADY HALL adjustment. (Note 4)
3. Replace the lens block. (Note 5)

Refer to [1-6-2. E : 62 : 11 (Shift Lens Overheating (Pitch))
Occurred] (Note 2).

Refer to [1-6-3. E : 62 : 12 (Shift Lens Overheating (Yaw))
Occurred] (Note 2).

Refer to [1-6-4. E : 62 : 20 (Abnormality of Thermistor)
Occurred] (Note 2).

Checking of flash unit or replacement of flash unit. (Note 3)

Inspect the flash memory (IC4302 on the MD-134 board).

DCR-DVD406E/DVD408/DVD408E/DVD808/DVD808E only.

DCR-DVD506E/DVD508/DVD508E/DVD908/DVD908E only.

After repair, be sure to perform “1-6. PROCESS AFTER FIXING FLASH ERROR”.

Perform adjustment by referring to “STEADY HALL Adjustment” in Service Manual, ADJ. After the adjustment, be sure to perform “GYRO Sensor
Sensitivity Adjustment”.

When the lens block was replaced, execute the necessary adjustment items referring to Service Manual, ADJ.
After the adjustment, make sure with the STEADYSHOT turned ON that the steadyshot functions appropriately in the handheld operation.
