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.

SAFETY CHECK-OUT

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

ATTENTION AU COMPOSANT AYANT RAPPORT

À LA SÉCURITÉ!

LES COMPOSANTS IDENTIFIÉS P AR UNE MARQUE 0 SUR LES DIAGRAMMES SCHÉMATIQUES ET LA LISTE DES PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE REMPLACER CES COMPOSANTS QUE PAR DES PIÈCES SONY DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU DANS LES SUPPLÉMENTS PUBLIÉS PAR SONY.

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, though 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.

1. POWER SUPPLY DURING REPAIRS

In this unit, about 10 seconds after power is supplied (8.4 V) 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 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 remote commander switch to the “ADJ” side.

Method 2.

Press the battery switch of the battery terminal using adhesive tape, etc.

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.)

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-69/71 board BH001). When

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

Correction

Remove the cassette, and insert it again after one hour. Clean with the optional cleaning cassette. Use the InfoLITHIUM battery.

Load the tape again, and perform operations from the beginning.

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 9 of CN1551 of VC-235 board) when focusing is performed when the control dial is rotated in the focus manual mode and the focus motor drive circuit (IC1553 of VC-235 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 0 of CN1551 of VC-235 board) when zooming is performed when the zoom lens is operated and the zoom motor drive circuit (IC1553 of VC-235 board) when zooming is not performed.

Inspect pitch angular velocity sensor (SE201 of SE-104/113 board) peripheral circuits.

Inspect yaw angular velocity sensor (SE202 of SE-104/113 board) peripheral circuits.
