SAFETY PRECAUTIONS

NOTICE: Comply with all cautions and safety related notes located on or inside the cabinet and on the chassis or pic-

ture tube. WARNING: Since the chassis of this receiver is connected

to one side of the AC power supply during operation, whenever the receiver is plugged in, service should not be attempted by anyone unfamiliar with the precautions neces-

sary when working on this type of receiver.

The following precautions should be observed:

1. Do not install, remove, or handle the picture tube in any manner unless shatterproof goggles are worn. People not so equipped should be kept away from the picture

tube while handling.

2. When service is required, an isolation transformer should be inserted between power line and the receiver before any service is performed on a “HOT” chassis receiver.

3. When replacing a chassis in the receiver, all the protective devices must be put back in place, such as barriers, nonmetallic knobs, adjustment and compartment cover-shields, isolation resistors, capacitors, etc.

4. When service is required, observe the original lead dress in the high voltage circuitry area.

5. Always use the manufacturer’s replacement components. Critical components as indicated on the circuit

diagram should not be replaced by another manufacturer’s, Furthermore, where a short circuit has occurred, replace those components that indicate evidence of overheating.

6. Before returning a serviced receiver to the customer, the service technician must thoroughly test the unit to be certain that it is completely safe to operate without dan-

ger of electrical shock, and be sure that no protective device built into the receiver by the manufacturer has become defective, or inadvertently defeated during ser-

vicing.

Therefore, the following checks should be performed for the continued protection of the customer and service technician.

Leakage Current Cold Check

With the AC plug removed from the 12OV AC 60Hz source,

place a jumper across the two plug prongs. Turn the AC power switch ON using an insulation tester (DC500V), connect one lead to the jumpered AC plug and touch the other lead to each exposed metal part (antennas, screwheads, metal overlays, control shafts, etc.), particularly any exposed metal part having a return path to the chassis should have a minimum resistor reading of 0.24MQ and a maximum resistor reading of 5.2MQ Any resistance value below or above this range indicates an abnormality which requires corrective action. Exposed metal part not having a return path to the chassis will indicate an open circuit.

Leakage Current Hot Check Plug the AC line cord directly into an AC 120V 60Hz outlet

(do not use an isolation transformer for this check). Turn the AC power ON. Using a “leakage Current Tester (Simpson’s Model 229 or equivalent)“, measure for current from all exposed metal parts of the cabinet (antennas, screwheads, overlays, control shafts, etc.) particularly any exposed metal part having a return path to the chassis or to a known earth ground (water pipe, conduit, etc.). Any current measured must not exceed 0.5mA.

RETURNING THE RECEIVER TO THE CUSTOMER. High Voltage

This receiver is provided with a hold down circuit for clearly

indicating that voltage has increased in excess of a prede-

termined value. Comply with all notes described in this

Service Manual regarding this hold down circuit when ser-

vicing, so that this hold down circuit is operated correctly.

Serviceman Warning With minimum BRIGHTNESS and CONTRAST, the operating high voltage in this receiver is lower than 35.0kV. Ir, case any component having influence on the high voltage is replaced, confirm that high voltage with minimum BRIGHT NESS and CONTRAST is lower than 350kV. To measure high voltage use a high impedance High Voltage Meter. Connect (-) to chassis earth and (+) to the CPT Anode button (See the following connection diagram).

NOTE: Turn the power switch OFF without fail before the

connection to the Anode button is made.

PRODUCT- SAFETY NOTICE

Many electrical and mechanical parts in HITACHI television receivers have special safety related characteristics. These 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. Replacements parts which have these special safety characteristics are identified in this Model Service Manual.

Electrical components having such features are identified with an A mark in the schematics and parts list in this Model Service Manual.

The use of a substitute replacement component which does not have the same safety characteristics as the HITACHI recommended replacement one, shown in the parts list in this Model Service Manual, may create shock, fire, X-Radiation, or other hazards.

Production Safety is continuously under review and new instructions are issued from time to time. For the latest information, always consult the current HITACHI Service Manual. A subscription to, or additional copies of HITACHI Service Manual may be obtained at a nominal charge from HITACHI SALES CORPORATION.

CPT ANODE

\

CHASSIS GROUND

X-Radiation TUBE: The primary source of X-Radiation in this receiver is

the picture tube. The tube utilized in this chassis is specially constructed to limit X-Radiation emission. For continued X-Radiation protection, the replacement tube must be the same type as the original HITACHI approved type.

When troubleshooting and making test measurements in a receiver with an excessive high voltage problem, avoid com-

ing unnecessarily close to the picture tube and the high volt-

age component.

This Service Manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair com-

plex products such as those covered by this manual. Improperly performed repairs can adversely affect the product

and its safety. Consumers should not risk trying to do the

necessary repairs and should instead refer to a qualified

service technician. WARNING

Lead in solder used in this product is listed by the California Health and Welfare agency as a known reproductive toxi-

cant which may cause birth defects or other reproductive

harm (California Health and Safety Code, Section 25249.5).

When servicing or handling circuit boards and other compo-

nents with lead in solder, avoid unprotected skin contact with the solder. Also, when soldering do not inhale any smoke or fumes produced.

SAFETY NOTICE

USE ISOLATION TRANSFORMER

WHEN SERVICING

Components having special safety characteristics are identified by A on the parts list in this Model Service Manual

and its supplements and bulletins. Before servicing this, it

is important that the service technician read and follow the

“Safety Precautions” and the “Product Safety Notices” in this

Service Manual.

For continued X-Radiation protection, replace picture tube with original type or Hitachi equivalent type.

POWER SOURCE

This television receiver is designed to operate on 120 Volts/

60Hz, AC house current. Insert the power cord into a 120 Volts/GOHz outlet.

NEVER CONNECTTHETVTO OTHERTHANTHE

SPECIFIED VOLTAGE OR TO DIRECT CURRENT.

Do not operate the chassis longer than is necessary to lo-

cate the cause of the excessive voltage.

1. Before turning ON the set, press and hold the POWER button and INPUT button for about

3 seconds.

2 After 3 seconds, a small square will appear in the

left lower corner. There are two different displays,

depending upon how long the INPUT button is

pressed and held. One shows A and D for audio

adjustment, and the other shows P and D for the picture adjustment.

3. To activate the adjustment mode, input a data value of 30 (D030), using the front panel cursor 4 ,F before any of the picture adjustments can be adjusted.

The same for the audio adjustment. To activate the audio adjustment, you need an input data value of 20 before any of the audio adjustments can be adjusted.

scope.

Adjustment Procedure

(1) When stereo L only signal (or R only signal) is

received, check that the output level ratio of Lch and

Rch is 15dB or more.

(Example)

When L only is received (100% modulation)

Adjustment Procedure

(1) When “MTS MODE” is set to “MONO” mode, check

that STEREO and MONO indication which have been ON are turned OFF and that monaural sound comes out from the right and left speakers.

(2) When “MTS MODE” is set to “STEREO” side, check

that STEREO and MONO indication which have been
