SAFETY PRECAUTIONS

  • The design of this product contains special hardware, many circuits and components specially for safety purposes. For continued protection no changes should be made to the original design unless authorized in writing by the manufacturer. Beplacement parts must be identical to those used in the original circuits. Service should be performed by qualified personnel only.
  • Alterations of the design or circuitry of the products should not be made Any design alterations or additions will void the manufacturer's warranty and will further relieve the manufacturer of responsibility for personal injury or property demage regulting therefrom
  • Many electrical and mechanical parts in the products have special safety-related characteristics. These characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in the parts list of Service manual. Electrical components having such features are identified by shading on the schematics and by (1) on the parts list in Service manual. The use of a substitute replacement which does not have the same safety characteristics as the recommended replacement part shown in the parts list
  • Use isolation transformer when bot chassis The chassis and any sub-chassis contrained in some products are connected to one side of the AC newer line. An isolation transformer of adequate capacity should be inserted between the product and the AC power supply point while performing any service on some products when the HOT chassis is exposed
  • Don't short between the LIVE side ground and NEUTRAL side grounding or EARTH side ground when repairing. Some model's power circuit is partly different in the GND. The difsome model's power circuit is party unrelent in the GND, the U. ference of the GND is shown by the LIVE (___) side GND, the NEU-TBAL ( ++---------------------------------tween the LIVE side GND and NEUTRAL side GND or EARTH side GND and never measure with a measuring apparatus (oscilloscope etc.) the LIVE side GND and NEUTRAL side GND or EARTH side GNID at the same time

If above note will not be kept, a fuse or any parts will be broken.

  • If any repair has been made to the chassis, it is recommended that the B1 setting should be checked or adjusted (See ADJUSTMENT OF B1 POWER SUPPLY).
  • The high voltage applied to the picture tube must conform with that specified in Service manual. Excessive high voltage can cause an increase in X-Bay emission arcing and possible component damage, therefore operation under excessive high voltage conditions should be kept to a minimum or should be prevented. If severe arcing occurs, remove the AC power immediately and determine the cause by visual inspection (incorrect installation, cracked or melted high voltage harness, poor soldering, etc.). To maintain the proper minimum level of soft X-Ray emission, components in the high voltage circuitry including the picture tube must be the exact replacements or alternatives approvided by the manufacturer of the com-
  • Do not check high voltage by drawing an arc. Use a high voltage meter or a high voltage probe with a VTVM. Discharge the nicture tube before attempting meter connection, by connecting a clin lead to the ground frame and connecting the other end of the lead through a 10kΩ 2W resistor to the anode button
  • When service is required, observe the original lead dress. Extra precaution should be given to assure correct lead dress in the high voltage circuit area. Where a short circuit has occurred these components that indicate evidence of overheating should be replaced. Always use the manufacturer's replacement components.
legistion Check
(Safety for Electrical Shock Hazard)

After re-assembling the product, always perform an isolation check on the exposed metal parts of the cabinet (antenna terminals video/audio input and output terminals. Control knobs metal cabinet screwheads, earphone jack, control shafts, etc.) to be sure the product is sale to operate without danger of electrical shock

Dielectric Strength Test

The isolation between the AC primary circuit and all metal parts exposed to the user, particularly any exposed metal part having a return path to the chassis should withstand a voltage of 1100V AC (r.m.s.) for a period of one second.

Withstand a voltage of 1100V AC (r.m.s.) to an appliance rated up to 120V and 3000V AC (rms) to an appliance rated 200V or more for a period of one second.)

This method of test requires a test equipment not generally found

Leakage Current Check

Plug the AC line cord directly into the AC outlet (do not use a line isolation transformer during this check.) Using a "Leakage Current Tester", measure the leakage current from each exposed metal part of the cabinet particularly any exposed metal part having a return both to the chassis to a known good earth ground (water nine etc.) Any leakage current must not exceed 0.5mA AC (r.m.s.). Alternate Check Method

Plug the AC line cord directly into the AC outlet (do not use a line isolation transformer during this check.). Use an AC voltmeter hav-Connect a 15000 10W resistor paralleled by a 0 1511E AC-type caaround (water nine, etc.). Measure the AC voltage across the resistor with the AC voltmator. Move the resister connection to each exposed metal part particularly any exposed metal part having a return path to the chassis, and measure the AC voltage across the resistor. Now reverse the plug in the AC outlet and repeat each measurement. Any voltage measured must not exceed 0.35V AC (r.m.s.). This corresponds to 0.5mA AG (r.m.s.).

11. High voltage hold down circuit check. After repair of the high voltage hold down circuit, this circuit shall be checked to operate correctly

See item "How to check the high voltage hold down circuit".

5 NOTE FOR REPAIRING SERVICE

This model's power circuit is partly different in the GND. The difference of the GND is shown by the LIVE (primary : 1) side GND and the NEUTRAL (secondary : ++) side GND. Therefore. care must be taken for the following points

  • (1) Do not touch the LIVE side GND or the LIVE side GND and the NEUTRAL side GND simultaneously. If the above caution is not respected, an electric shock may be caused. Therefore, make sure that the power cord is surely removed from the receptacle when, for example, the chassis is pulled out.
  • (2) Do not short between the LIVE side GND and NEUTRAL side GND or never measure with a measuring apparatus (oscilloscope, etc.) the LIVE side GND and NEUTRAL side GND at the same time. If the above precaution is not respected, a fuse or any parts will be broken.
  • ♦ Since the circuit diagram is a standard one, the circuit and circuit constants may be subject to change for improvement without any notice.

  • 2. Remove three screws 2 retaining driver unit ass'y 1.
  • 3. Remove a screw ③ retaining the main PWB ass'y and remove it.
REMOVING THE SUB PWB ASS'Y

(Infrared Receptor)

  • 1. Remove three screws (6) retaining housing (4) and honger (1).
  • 2. Remove a screw (B) retaining hunger cover (5) and headband (7).
  • 3. Remove sub PWB ass'y (9) and filter (10) from the inside.
  • 4. Remove a screw (1) retaining huger (1) and headband (7).
