• SUPPLIED ACCESSORIES

Check that the following accessories are supplied with your camcorder.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following safety checks before releasing the set to the customer.

1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and bridges.

2. Check the interboard wiring to ensure that no wires are "pinched" or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair . Point them out to the customer and recommend their replacement.

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

AUS : Australian model HK : Hong Kong model CN : Chinese model JE : Tourist model

4. Look for parts which, through functioning, show obvious signs

of deterioration. Point them out to the customer and recommend their replacement.

5. Check the B+ voltage to see it is at the values specified.

6. Flexible Circuit Board Repairing

• Keep the temperature of the soldering iron around 270˚C during repairing.

• Do not touch the soldering iron on the same conductor of the circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering or unsoldering.

SERVICE NOTE

1. POWER SUPPLY DURING REPAIRS

In this unit, about 10 seconds after power is supplied (8.4V) to the battery terminal using the service power cord (J-6082-223-A), the power is shut off so that the unit cannot operate. This following two methods are av ailable to prev ent this. Take note of which to use during repairs.

Method 1.

Connect the servicing remote commander RM-95 (J-6082-053-B) to the LANC jack, and set the remote commander switch to the “ADJ” side.

Method 2.

Use the DC IN terminal. (Use the AC power adaptor.)

SELF-DIAGNOSIS FUNCTION

1. Self-diagnosis Function

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

2. Self-diagnosis Display

When problems occur while the unit is operating, the counter of the viewfinder or Display window 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.

3. Service Mode Display

The service mode display shows up to six self-diagnosis codes shown in the past.

3-1. Display Method

While pressing the “STOP” key, set the switch from OFF to “VTR or PLAYER”, and continue pressing the “STOP” key for 5 seconds continuously. The service mode will be displayed, and the counter will show the backup No. and the 5-character self-diagnosis codes.

By rotating the control dial, past self-diagnosis codes will be shown in order. The backup No. in the [] indicates the order in which the problem occurred. (If the number of problems which occurred is less than 6, only the number of problems which occurred will be shown.)

Turning OFF the power supply will end the service mode display.

Note: The “self-diagnosis display” data will be backed up by the coin-type lithium battery (CF-66/67 board BH001). When

this coin-type lithium battery is disconnected, the “self-diagnosis display” data will be lost by initialization.

Symptom/State

Difficult to adjust focus (Cannot initialize focus.)

Zoom operations fault (Cannot initialize zoom lens.)

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.)

Correction

Inspect the lens block focus reset sensor (Pin qs of CN551 of VC- 234 board) when focusing is performed when the control dial is rotated in the focus manual mode and the focus motor drive circuit (IC551 of VC-234 board) when the focusing is not performed.

Note: Use the remote commander RM-95 only for the model without the

focus dial.

Inspect the lens block zoom reset sensor (Pin qf of CN551 of VC234 board) when zooming is performed when the zoom lens is operated and the zoom motor drive circuit (IC551 of VC-234 board) when zooming is not performed.

Inspect pitch angular velocity sensor (SE451 of SE-101 board) peripheral circuits.

Inspect yaw angular velocity sensor (SE452 of SE-101 board) peripheral circuits.
