1. NOTES DE SERVICE IMPORTANTES

AVANT DE RENDRE LE MAGNETOSCOPE

Avant de rendre le magnetoscope a I’utilisateur, effectuer

les verifications de securite suivantes.

1. Verifier toutes les gaines de fil pour etre sur que les fils ne sont pas pin& ou que le materiel n’est pas coin& entre le chassis et les autres pieces metalliques dans le magnetoscope.

2. Verifier tous les dispositifs de protection tels que les boutons de commande non metalliques, les materiaux d’isolement, le dos du coffret, les couvercles de compartiment et ajustement ou les boucliers, les reseaux de resistance / condensateur d’isolement,

les isolateurs mecaniques, etc.

3. Pour etre stir qu’il n’y a aucun risque de choc electrique, verifier le courant de fuite de la maniere 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 a pinces et connecter une resistance

de 10 watts I,5 kohm en parallele avec un condensateur de 0,15 PF en serie avec des pieces du coffret metallique exposees et une masse de terre connue telle qu’un tuyau ou un conduit d’eau.

.

Utiliser un VTVM ou VOM avec une sensibilite de 1000 ohms par volt ou plus ou mesurer la chute de

tension CA entre la resistance (voir diagramme).

.

Deposer la connexion de la resistance a toutes les pieces metalliques exposees ayant un parcours de

retour au chassis (connexions d’antenne, coffret metallique, t&es devis, boutons et arbres de commande, etc.) et mesurer lachutede tension CAentre la resistance. lnverser lafiche CA (unefiche intermediaire non polarisee doit etre utilisee a seule fin de faire ces verifications.) sur I’appareil et repeter les mesures de tension CA pour chaque piece metallique exposee. Toute lecture de 0,45 V rms (ceci correspond a 0,3 mA rms CA) ou plus est excessive et signale un danger de choc qui doit etre corrige avant de rendre le magnetoscope a son

utilisateur.

4-5-l. Before replacement

The CCD image sensor is more sensitive to electrostatic breakage than CMOS LSI. Therefi

prevent electrostatic damage must be taken when it is replaced. Ground the soldering iron. Ground also the human body, using the wrist strap(through an 1 Mohm resistor). Until the CCDsensor is mounted on the PWB, fit it to the conductive sponge, and short-circuit the foot lead. Take utmost care so that the surface glass of CCD sensor and optical filter are not contaminated and damaged. If any contamination is found, for example fingerprint, wipe it off with silicon paper or clean chamois skin. When replacing the CCD sensor, use the antistaic grounded soldring iron, and perform quickly so!dering.

4-5-2. Removal of CCD

1) Unsolder the CCD sensor leads from the sensor PWB.

2) Take out the sensor PWB.

3) Remove the two screws (6), and remove the sensor holder and CCD sensor.

4-5-3. Mounting of CCD

1) Place the lens unit upright (since the CCD sensor mount ID faces upward, care must be taken so as not to damage the front lens of unit), put the crystal filter first and then the dust protection rubber into the CCD holder of lens unit. Set the crystal unit with its thin side toward the lens unit.

2) Place the CCD sensor so that the its No. 1 pin is at the right lower (Positioning hole to be at right), and put the CCD sensor into the CCD holder. For smooth and tight fitting, press the right lower part of back of CCD sensor, and then press the left upper part.

Note: Pay attention to the direction of CCD sensor.

3) Place the sensor holder so that its two round markings be visible, and fix the sensor holder with HZ001 3TAFF).

4) Mount the sensor PWB so that the CCD sensor leads go thorough the PWB holes.

5) Solder the CCD sensor lead to the sensor PWB.

Note: Take care not to apply excessive heat.

6-I. ADJUSTMENT OF VCR SECTION 6-l-l m Before starting the electric circuit adjustment

0 Electric circuit adjustment becomes necessary, in most cases, when any of the wear mechanical parts or the video head

has been replaced. Before starting the electric circuit adjustment, be sure to check that the mechanical parts work well

(i.e., the mechanical parts have all been perfectly adjusted). In case a trouble or troubles are found in the electric circuitry, be sure to pinpoint the cause(s) by using the measuring instruments described below. After locating the trouble spot(s), then proceed to repair, replacement or adjustment. Do not change the positions of the controls when adequate

measuring instruments are not available.

0 In order to implement a higher-density, smaller machine, most of the electric circuit parts used on the Circuit Boards

are of small-sized, surface-mounted type. For replacing part(s) as after-sales service, work with a soldering iron as

speedily as possible. The heat resistance of the surface-mounted components is poor, when compared with the larger-

sized discrete parts used for television sets and stationary decks, owning to their small sizes. Therefore, exercise due

care to avoid long-time exposure of the pins of these parts to the heat of the soldering iron which may possibly damage

them. Such care should be exercised especially for chip-layer capacitor replacement. It is advisable to use a

temperature-controlled ceramic soldering iron (temperature at the tip: 250°C, contacting time: less than 5 seconds).
