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.

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 temperatur e 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.

SAFETY CHECK-OUT

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

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 .

ATTENTION AU COMPOSANT AYANT RAPPORT

À LA SÉCURITÉ! LES COMPOSANTS IDENTIFÉS P AR UNE MARQUE 0 SUR LES DIAGRAMMES SCHÉMA TIQUES ET LA LISTE DES PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE REMPLACER CES COMPOSANTS QUE PAR DES PIÈSES SONY DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU DANS LES SUPPÉMENTS PUBLIÉS PAR SONY.

SERVICE NOTE

1. POWER SUPPLY DURING REPAIRS

In this unit, about 10 seconds after power is supplied to the battery terminal using the regulated power supply (8.4V), the po wer is shut of f so that the unit cannot operate. These following two methods are available to prevent 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 commander switch to the “ADJ” side.

Method 2.

Use the DC IN terminal. (Use the AC power adaptor. (AC-L10, AC-VQ800 etc. ))

2. TO TAKE OUT A CASSETTE WHEN NOT EJECT (FORCE EJECT)

1 Refer to 2-3. to remove the upper handle block assembly. 2 Refer to 2-5. to remove the cabinet (L) assembly. 3 Refer to 2-5. to remove the mechanism deck (Including VC-242D board and DD-138D board). 4 Remove DD-138D board from the mechanism deck (Including VC-242D board). 5 Remove the CN022 (27P 0.3 mm) of VC-242D board. 6 Supply +4.5V from the DC power supply to the loading motor and unload with a pressing the cassette compartment.

What to do when a user forgets a password

This camcorder has the forced log insertion function. A passw ord is inputted, and this function is set up. When this function was set up, this camcorder doesn’t move if the memory stick which memorize a correct logo isn’t inserted. To release the for ced logo function, the correct password must be input. This password is memorized in the IC1105 (EEPROM) on VC-242D board. Therefore, when a user for gets the password, replace the IC1105. This IC1105 memorizes the HRS METER data (Hour meter data: page A, address 00 to 13), too. Therefor e, replace the IC1105 in the following order to copy the HRS METER data.

Replacing procedure:

1) Note down the data of page A, address 00 to 13.

2) Replace IC1105 (EEPROM) on VC-242D board.

3) To page A, address 00 to 13, input the data noted down. (Refer to “HRS METER (Hours meter)” of “5-4. SERVICE MODE”)

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 , LCD screen or LCD window 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.

Note: The “self-diagnosis display” data will be backed up by the coin-type lithium battery of CK-093 board BT250. When CK-093 board is removed,

the “self-diagnosis display” data will be lost by initialization.

2. SELF-DIAGNOSIS DISPLAY

When problems occur while the unit is operating, the counter of the viewfinder, LCD screen or LCD window consists of an alphabet and 4-digit 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 “VCR 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.

3-2. Switching of Backup No.

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.) [1] : Occurred first time [4] : Occurred fourth time [2] : Occurred second time [5] : Occurred fifth time [3] : Occurred third time [6] : Occurred the last time

3-3. End of Display

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

when focusing is performed when the control dial is rotated in the focus manual mode, and the focus motor drive circuit (IC140 of LA-026 board) when the focusing is not performed.

Inspect the lens block zoom reset sensor (

Pin ws of LA-026 board

) when zooming is performed when the zoom lens is operated and the zoom motor drive circuit (IC140 of LA-026 board) when zooming is not performed.

Inspect pitch angular velocity sensor (SE601 or SE602 of SE-108 board) peripheral circuits.

Inspect yaw angular velocity sensor (SE600 or SE603 of SE-108 board) peripheral circuits.
