1. IMPORTANT SERVICE NOTES

BEFORE RETURNING THE VIDEO CAMERA RECORDER

Before returning the video camera recorder to the user, perform the following safety checks.

1. Inspect all lead dress to make certain that leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the video camera recorder.

2. Inspect all protective devices such as non-metallic control knobs, insulating materials, cabinet backs, adjustment and compartment covers or shields, isolation resistor/capacitor networks, mechanical insulators etc.

3. To be sure that no shock hazard exists, check for leakage current in the following manner.

· Plug the AC line cord directly into a 120 volt AC outlet (Do not use an isolation transformer for this test).

· Using two clip leads, connect a l.5k ohm, 10 watt resistor paralleled by a 0.15µF capacitor in series with all exposed metal cabinet parts and a known ground, such as a water pipe or conduit.

· Use a VTVM or VOM with 1000 ohm per volt, or higher sensitivity or measure the AC voltage drop across the resistor (See Diagram).

· Move the resistor connection to all exposed metal parts having a return path to the chassis (antenna

connections, metal cabinet, screw heads, knobs and control shafts, etc.) and measure the AC voltage drop across the resistor. Reverse the AC plug (a non polarized adaptor plug must be used but only for the purpose of completing these checks) on the set and repeat the AC voltage measurements for each exposed metallic part. Any reading of 0.45V rms (this corresponds to 0.3mA rms AC.) or more is excessive and indicates a potential shock hazard which must be corrected before returning the video camera recorder to the user.

AVANT DE RENDRE LE MAGNETOSCOPE Avant de rendre le magnétoscope à l’utilisateur, effectuer

les vérifications de sécurité suivantes.

1. Vérifier toutes les gaines de fil pour être sûr que les fils ne sont pas pincés ou que le matériel n’est pas coincé entre le châssis et les autres pièces métalliques dans le magnétoscope.

2. Vérifier tous les dispositifs de protection tels que les boutons de commande non métalliques, les matériaux d’isolement, le dos du coffret, les couvercles de compartiment et ajustement ou les boucliers, les réseaux de résistance / condensateur d’isolement, Ies isolateurs mécaniques, etc.

3. Pour être sûr qu’il n’y a aucun risque de choc électrique, vérifier le courant de fuite de la maniére suivante.

· Brancher le cordon d’alimentation secteur directement dans une prise de courant de 120 volts. (Ne pas utiliser de transformateur d’isolement pour cet essai).

· Utiliser deux fils à pinces et connecter une résistance de 10 watts 1,5 kohm en parallèle avec un condensateur de 0,15 µF en série avec des pièces du coffret métallique exposées et une masse de terre connue telle qu’un tuyau ou un conduit d’eau.

· Utiliser un VTVM ou VOM avec une sensibilité de 1000 ohms par volt ou plus ou mesurer la chute de tension CA entre la résistance (voir diagramme).

· Déposer la connexion de la résistance à toutes les pièces métalliques exposées ayant un parcours de

retour au châssis (connexions d’antenne, coffret métallique, tétes de vis, boutons et arbres de commande, etc.) et mesurer la chute de tension CA entre la résistance. Inverser la fiche CA (une fiche intermédiaire non polarisée doit être utilisée à seule fin de faire ces vérifications.) sur l’appareil et répéter les mesures de tension CA pour chaque piéce métallique exposée. Toute lecture de 0,45 V rms (ceci correspond à 0,3 mA rms CA) ou plus est excessive et signale un danger de choc qui doit être corrigé avant de rendre le magnétoscope à son utilisateur.

6-2. Precautions

(1) When replacing any part, always replace the cut washer that was

removed with a new one.

(2) This mechanism does not have control adjustment. If the control

cannot be set as required, clean and or replace parts.

(3)On the oil

a) Always use the specified oil. (Using another kind of oil can cause

various kinds of trouble.)

b) Always use clean oil, without any mixed-in dirt, to lubricate bearings.

(Using oil with dirt mixed in can cause the bearings to wear or to stick.)

c) One drop of oil is the amount shown in the Fig. 1, on the point of a

pin.

(4)Perform circuit repair, tape running adjustment, etc. with the cassette

controller assembly attached to the mechanism.

(5)When operating the mechanism separately, apply voltage to the

loading motor. However, the terminal voltage must be DC3V~4V. (When the mechanism is connected to the main PWB, do not apply external voltage to the loading motor. It may cause a trouble.) (Forcing the gears to turn by hand entails danger of breakage.) If the mechanism is separated from the unit, the capstan motor may rub and be damaged if spacing under the mechanism is inadequate.

(6)To install the cassette controller, push section A in the Fig. 2. Do not

push anything else.

(7)Do not deform any of the mechanical parts.

7. MECHANICAL ADJUSTMENTS AND CHECKS

The items discussed here relate to general on-site servicing (field servicing). Adjustments and replacements that require sophisticated facilities, jigs and technology are omitted. In addition, in order to maintain the characteristics that the unit has when it is new, not only are inspection and maintenance necessary, but it is absolutely necessary that, for example, the tape not be damaged, and always use jigs for adjustments that require them.

(1)Always set the power supply and state of the unit as follows Notes for mechanism adjustments and checks.

AC adapter used, with cassette controller assembly AC adapter used, without cassette controller assembly (Independent Mechanism) DC3V, without cassette controller assembly (Independent Mechanism) (2) When the mechanism is connected to the main PWB, do not apply external voltage to the loading motor. It may cause a trouble.

(3) Always run the tape with the cassette controller assembly attached.

7-1. Checking the playback (recording) winding torque AC adapter used, with cassette controller assembly

(1)Set the torque cassette with the cassette controller assembly attached, then, in SP recording mode (playback mode if a signal has

already been recorded in SP mode on the tape), confirm that the torque on the winding side is within the standard.

(If there is torque ripple, read the center value.)

0.70 +0.4/-0.3mN·m, ripple 0.5mN·m or less

10. ADJUSTING THE ELECTRICAL CIRCUITS

Before starting the electric circuit adjustment

• The adjustment methods described herein are used, in most cases, when the expendable mechanical parts, including the video head, have been replaced, at which time the electrical circuits need to be readjusted. Before adjusting the electrical circuits, make sure that the mechanism works properly (i.e., the mechanism is properly adjusted). Incase of the occurrence of any problem to the electrical circuits, be sure to use the specified measuring instruments to locate the area to which the problem is occurring, and then take the necessary action, including repair, replacement or adjustment, exactly as instructed in the electrical adjustment methods that will follow. Do not attempt to make adjustments without using the proper measuring instruments.

• This machine is configured so that the electrical circuits inside its PWB unit are composed, for the most part, of highdensity, small surface-mounted component parts for downsized machine body. To perform repair service or parts replacement, do so using a soldering iron, but in as short a time as possible; this is because surface-mounted component parts are generally so small in size and susceptible to heat, as compared with the large discrete parts used in TV sets, desk-top video decks, etc., that attempting to heat their electrodes for a longer time than is necessary with a soldering iron may result in their becoming defective. This applies particularly when replacing the laminated chip capacitors. For this purpose, ceramic soldering irons with a temperature regulator are recommended (iron tip temperature 250°C and soldering time 5 seconds or shorter).

10-2-3. Adjusting the camera unit

(1)Preparations for adjustments and items to be checked

1) Set up the light box so that the entire pattern is evenly lit. Set the color temperature to 3200°K.

2) Use test patterns that are not dirty nor discoloured.

3) If the electrical circuitry gets in trouble, be sure to pinpoint the trouble spot with a measuring instrument and repair or replace the defective part.

(2)Remote control for servicing RRMCG0033TASA

To adjust the camera section of this machine, the remote control for servicing (RRMCG0033TASA) is used. The adjustment is made in such a manner that the remote control writes necessary data by way of the microprocessor to the specific addresses on the

PROM (IC2).

1) To adjust the camera: Press the "CONTINUE" key first and then the "CAM ADJ" key. This will show

CAM ADJ

on the LCD screen, thereby having the camera unit ready for the adjustments.

2) Descriptions of the displays

CAM ADJ (Indicates the camera adjustment mode.)

(Address value) (Data value)

* The address values for this machine range from 0000 to 07FF. * The data include byte data (the last two digits are effective) and 2-byte data (the last three digits are effective).

3) Descriptions of the remote control keys

"FF" key: Increases the address and data values. "REW" key: Decreases the address and data values. "PLAY" key: Specifies addresses and calls the data.

This key also fixes the data values.

"STOP" key: Clears the data to enable the selection of address.

VL-WD650U

4) Operation flow

FF or REW PLAY PLAY STOPFF or REW

Address is selected and specified, with the data called. Then the called data are selected and fixed. The operation flows in this sequence.

5) When the adjustment is complete: Press the "CONTINUE" key to let the "CAM ADJ" display disappear from the screen. Note: Before terminating the adjustments, make sure that the adjustment mode is neither the auto-focus function adjustment

mode nor the camera signal system adjustment mode (these modes are mentioned later).

• Camera unit adjustment modes The camera unit is adjusted in two types of modes: the auto-focus function adjustment mode and the camera signal system adjustment mode.

Note: E

PROM contains the adjustment item data as shown below. If it is changed, data rewriting and confirmation of latest data

must be performed. E2PROM of CCD PWB(IC2) Lens data and Signal system adjustment data

(3)Auto-focus function adjustment mode

• The camera unit uses a microprocessor-controlled auto-focus zoom lens. The auto-focus circuit incorporated in this unit is designed to execute the image processing where the focusing action is done by taking advantage of the fact that the high-frequency components in the image signals increase as the focus intensifies. Moreover, to achieve high magnifying power with a small lens, the camera unit incorporates the inner focus system in which the focus is shifted by moving the master lens (rear lens) back and forth. This inner focus system is a full-range focus type by which the focus can be shifted from approximately 50 mm to the infinity. It should be noted, however, that since the closest subject distance at the telephoto end is fixed at 1.8 m, subjects in a closer range than 1.8 m at the telephoto end will be out of focus. For this reason, the unit is designed so the zoom control is automatically shifted to the wide angle side until the position is found where the subject can be focused on.

In the auto-focusing system of this until, the following constitute the important factors:

• Master lens position detection data

• Iris position detection data

• Zoom lens position detection data

These detection data are handled and stored by the microprocessor, lens by lens, into the E

PROM.

Therefore, in the following cases, the auto-focus function adjustment is required:

• When the lens has been replaced

• When the CCD has been replaced

• When the E

PROM has been replaced

• When the MAIN PWB has been replaced

1) Shifting to the auto-focus function adjustment mode Set the data for the address "0000" to " 01".

]

This makes the screen fade temporarily in white and shifts to the auto-focus function adjustment mode.

* When this adjustment mode has been shifted to, make the adjustment according to (5) Camera unit adjustment procedure. * In this adjustment mode, the lens can not be operated.

2) Shifting to the normal operation mode Set the data for the address "0000" to " FF".

]

This makes the screen fade temporarily in white and shifts to the normal operation mode.

]

Press the "CONTINUE" key, and the "CAM ADJ" display goes out of the screen, enabling the normal operation.

VL-WD650U

(4)Camera signal system adjustment mode

In the camera signal system adjustment mode, the automatic white balance is disabled to allow for the adjustment of the camera unit. At this time, the white balance mode is fixed at the INDOORS mode and the focus mode is switched to the manual focus mode.

1) Shifting to the camera signal system adjustment mode Set the data for the address "0000" to " 00".

]

This shifts the camera signal system adjustment mode. * When this adjustment mode has been shifted to, make the adjustment according to (5) Camera unit adjustment procedure.

2) Shifting to the normal operation mode Set the data for the address "0000" to " FF".

]

This shifts the mode to the normal operation mode.

]

Press the "CONTINUE" key, and the "CAM ADJ" display goes out of the screen, enabling the normal operation.

VL-WD650U

Item

(1) Auto-focus adjustment

Set the unit to the auto-focus function adjustment mode and write data to the address "0000" one after another. This executed the adjustments automatically. The items to be adjusted are as listed below. Every time an adjustment is made properly, the data "FF" is written to the address. After each adjustment, make sure that the adjustment has been made properly, and then go on to the next adjustment item.

Address Data Adjustment item

0000 0012 WIDE end adjustment

0006 WIDE end focus ∞ position adjustment 0008 TELE end focus ∞ position adjustment 000D Zoom tracking adjustment

Note 1: To adjustment of ∞ position is executed by actually picking up the image of subject. For this adjustment use the subject with

clear profile. Especially, if the adjustment of TELE end focus ∞ position is made without picking up the image of remote subject, adjustment failure may occur.

Adjustment of WIDE end focus ∞ position: 3 m or more Adjustment of TELE end focus ∞ position: 50 m or more

Note 2: In case of ∞ position adjustment the field depth is important to ensure the adjustment accuracy. If the field depth is high,

the focus becomes too stable , which may cause incorrect adjustment of ∞ position. Therefore the adjustment must be made with low field depth (with iris opened).

The iris can be opened with the high-speed shutter.

1. It returns to the normal operation mode.

2. In the normal operation mode, set the high-speed shutter mode until the iris is opened. (Refer to the operation manual.)

3. Display “CAM ADJ” with the remote control for service.

4. It shifts to the auto-focus adjustment mode.

5. Perform the ∞ position adjustment.

6. After completing the ∞ position adjustment, return the high-speed shutter mode to the normal mode.

Adjustment method

(2)Iris basic adjustment

This is for adjusting the operating point of the hole element installed in the iris meter of the lens. The adjustment is automatically done by sequentially writing the data at the address "0000" in the camera signal system adjustment mode.The items to be adjusted are as listed below. Every time an adjustment is made properly, the data "00FF" is written to the address.

Address Data Adjustment item

0000 0009 Hall offset adjustment

000A Iris offset adjustment 000B Iris close adjustment

In the camera signal system adjustment mode (write the data " 00" to the address "0000"), set the unit to the adjustment mode.

(3) Black balance adjustment/A/F noise adjustment

1)Prior to the adjustment, initialize the data for the addresses "0026", "0028", "002A", "002C", "002E", "0030". Write " FF" to all of these address.

2) Write the data " 01" to the address "0001" This starts the adjustment automatically. When the adjustment is completed properly, the data "00FF" is written automatically.
