1.PRECAUTIONS

Prior to shipment from the factory,the products are strictly inspected to conform with recognized product safety and

Electrical codes of the countries in which they are to be sold.However, in order to maintain such compliance,it is

equally important to implement the following precautions when a set is being serviced.

1-1.Safety Precautions

1) Before returning an instrument to the customer, always

make a safety check of the entire instrument, including, but

not limited to, the following items:

(1) Be sure that no built-in protective devices are defective

or have been defeated during servicing.

(1) Protective shields are provided to protect both the

technician and the customer. Correctly replace all

missing protective shields, including any remove for

servicing convenience.

(2) When reinstalling the chassis and/or other

assembly in the cabinet, be sure to put back in place

all protective devices, including, but not limited to,

nonmetallic control knobs, insulating fish papers,

adjustment and compartment covers/shields, and

isolation resistor/capacitor networks. Do not operate

this instrument or permit it to be operated without all

protective devices correctly installed and functioning.

(2) Be sure that there are no cabinet opening through which

adults or children might be able to insert their fingers

and contact a hazardous voltage. Such openings

include, but are not limited to, excessively wide

cabinet ventilation slots, and an improperly fitted

and/or incorrectly secured cabinet back cover.

(3) Leakage Current Hot Check-With the instrument

completely reassembled, plug the AC line cord

directly into a 120V AC outlet. (Do not use an

isolation transformer during this test.) Use a leakage

current tester or a metering system that complies with

American National Standards institute (ANSI) C101.1

Leakage.

Current for Appliances and underwriters Laboratories

(UL) 1270 (40.7). With the instrument’s AC switch

first in the ON position and then in the OFF position,

measure from a known earth ground (metal water pipe,

conduit, etc.) to all exposed metal parts of the

instrument (antennas, handle brackets, metal cabinets,

screwheads, metallic overlays, control shafts, etc.),

especially and exposed metal parts that offer an

electrical return path to the chassis.

Any current measured must not exceed 0.5mA.

Reverse the instrument power cord plug in the outlet

and repeat the test.

AC Leakage Test

Any measurements not within the limits specified

herein indicate a potential shock hazard that must be

eliminated before returning the instrument to the

customer.

(4) Insulation Resistance Test Cold Check-(1) Unplug the

power supply cord and connect a jumper wore

between the two prongs of the plug. (2) Turn on the

power switch of the instrument. (3) Measure the

resistance with an ohmmeter between the jumpered

AC plug and all exposed metallic cabinet parts on the

instrument, such as screwheads, antenna, control

shafts, handle brackets, etc. When an exposed

metallic part has a return path to the chassis, the

reading should be between 1 and 5.2 megohm. When

there is no return path to the chassis, the reading must

be infinite. If the reading is not within the limits

specified, there is the possibility of a shock hazard,

and the instrument must be re-pared and rechecked

before it is returned to the customer.

2) Read and comply with all caution and safety related

notes non or inside the cabinet, or on the chassis.

voltage, and (5) antenna wiring. Always inspect in all

areas for pinched, out-of-place, or frayed wiring. Do

not change spacing between a component and the

printed-circuit board, Check the AC power cord for

damage.

5) Components, parts, and/or wiring that appear to have

overheated or that are otherwise damaged should be

replaced with components, parts and/or wiring that

meet original specifications. Additionally determine

the cause of overheating and/or damage and, if

necessary, take corrective action to remove and

potential safety hazard.

3) Design Alteration Warning-Do not alter of add to the

mechanical or electrical design of this instrument.

Design alterations and additions, including but not

limited to, circuit modifications and the addition of

items such as auxiliary audio output connections,

might alter the safety characteristics of this instrument

and create a hazard to the user. Any design alterations

or additions will make you, the service, responsible

for personal injury or property damage resulting there

from.

4) Observe original lead dress. Take extra care to assure

correct lead dress in the following areas:

(1) near sharp edges, (2) near thermally hot parts (be

sure that leads and components do not touch

thermally hot parts), (3) the AC supply, (4) high

1-2 Servicing Precautions

CAUTION: Before servicing Instruments covered by this

service manual and its supplements, read and follow the

Safety Precautions section of this manual.

Note: If unforeseen circument create conflict between the

following servicing precautions and any of the safety

precautions, always follow the safety precautions.

Remember; Safety First

1-2-1 General Serving Precautions

(1) a. Always unplug the instrument’s AC power cord from

the AC power source before (1) removing or

reinstalling any component, circuit board, module or

any other instrument assembly. (2) disconnecting

any instrument electrical plug or other electrical

connection. (3) connecting a test substitute in

parallel with an electrolytic capacitor in the

instrument.

6) Product Safety Notice-Some electrical and mechanical

parts have special safety-related characteristics which

are often not evident from visual inspection, nor can

the protection they give necessarily be obtained by

replacing them with components rated for higher

voltage, wattage, etc. Parts that have special safety

characteristics are identified by shading, an (

(

) on schematics and parts lists. Use of a substitute

replacement that does not have the same safety

characteristics as the recommended replacement part

might created shock, fire and/or other hazards.

Product safety is under review continuously and new

instructions are issued whenever appropriate.

b. Do not defeat any plug/socket B+ voltage interlocks

with which instruments covered by this service

manual might be equipped.

c. Do not apply AC power to this instrument and/or any

of its electrical assemblies unless all solid-state

device heat sinks are correctly installed.

d. Always connect a test instrument’s ground lead to

the instrument chassis ground before connecting the

test instrument positive lead. Always remove the test

instrument ground lead last.

Note: Refer to the Safety Precautions section ground

lead last.

(2) The service precautions are indicated or printed on the

cabinet, chassis or components. When servicing,

follow the printed or indicated service precautions

and service materials.

(3) The components used in the unit have a specified flame

resistance and dielectric strength.

When replacing components, use components which

) or a

Page 4

have the same ratings, by ( ) or by ( ) in the

circuit diagram are important for safety or for the

characteristics of the unit. Always replace them with

the exact replacement components.

(4) An insulation tube or tape is sometimes used and some

components are raised above the printed wiring board

for safety. The internal wiring is sometimes clamped

to prevent contact with heating components. Install

such elements as they were.

(5) After servicing, always check that the removed screws,

components, and wiring have been installed correctly

and that the portion around the serviced part has not

been damaged and so on. Further, check the insulation

between the blades of the attachment plus and

1-3 ESD Precautions

Electrostatically Sensitive Devices (ESD)

Some semiconductor (solid static electricity) devices can

be damaged easily by static electricity.

Such compo9nents commonly are called Electrostatically

Sensitive Devices (ESD). Examples of typical ESD devices

are integrated circuits and some field-effect transistors and

semiconductor chip components. The following techniques

of component damage caused by static electricity.

(1) immediately before handling any semiconductor

components or semiconductor-equipped assembly,

drain off any electrostatic charge on your body by

touching a known earth ground. Alternatively, obtain

and wear a commercially available discharging wrist

strap device, which should be removed for potential

shock reasons prior to applying power to the unit

under test.

(2) after removing an electrical assembly equipped with

ESD devices, place the assembly on a conductive

surface such as aluminum foil, to prevent electrostatic

charge buildup or exposure of the assembly.

accessible conductive parts.

1-2-2 Insulation Checking Procedure

Disconnect the attachment plug from the AC outlet and

turn the power ON. Connect the insulation resistance meter

(500V) to the blades of the attachment plug. The insulation

resistance between each blade of the attachment plug and

accessible conductive parts (see note) should be more than

1 Megohm.

Note: Accessible conductive parts include metal panels,

input terminals, earphone jacks, etc.

devices.

(6) Do not remove a replacement ESD device from its

protective package until immediately before you are

ready to install it. (Most replacement ES devices are

packaged with leads electrically shorted together by

conductive foam, aluminum foil or comparable

conductive materials).

(7) Immediately before removing the protective materials

from the leads of a replacement ES device touch the

protective material to the chassis or circuit assembly

into which the device will be installed.

CAUTION: Be sure no power is applied to the chassis or

circuit, and observe all other safety precautions.

(8) Minimize bodily motions when handling unpackaged

replacement ESD devices. (Otherwise harmless

motion such as the brushing together of your clothes

fabric or the lifting of your foot from a carpeted floor

can generate static electricity sufficient to damage an

ESD device).

(3) Use only a grounded-tip soldering iron to solder or

unsolder ESD device.

(4) Use only an anti-static solder removal devices. Some

solder removal devices not classified as “anti-static”

can generate electrical charges sufficient to damage

ESD devices.

(5) Do not use freon-propelled chemicals. These can

generate electrical charges sufficient to damage ESD

1-4. Handling the LCD Module

In case the screen is damaged and the internal liquid leaks,do not suck or drink the internal fuid. Nor do you touch it either ,otherwise you might be poisoned or get a rash with your skin,If the internal fluid enters your mouth,rinse with water.If itadheres to your skin or clothes,wipe it away with alcohol and then wash with water. If it enters your eyes,wash with running water immediately.

Precautions for handling the LCD module

The LCD module can be easily damaged during assembly or disassembly.Observe the following precautions when handling the LCD module:

1. When installing the LCD module in the LCD cover,be sure to seat it so that it is properly aligned and maximum visibility of the display is maintained.

4. Glass is used in the panel ,so be careful not to drop it or let it strike a hard object ,which could cause breakage or cracks.

5. CMOS-LSI circuits are used in the module,so guard against damage from electrostatic discharge.Be sure to wear aa wrist or ankle ground when handling the module.

2. If the panel’s surface gets dirty,wipe it with cotton or a soft cloth.If it is still dirty,try breathing on the surface to create a light condensate and wipe it again.If the surface is very dirty,we recommend a CRT cleaning agent.Apply the agent to a cloth and then wipe the panel’s surface .Do not apply cleanser directly to the panel .Also,neverscratch the suface.

3. If water or other liquid is left on the panel’s surface for a long period,it can change the screen’s tint or stain it. Be sure to quickly wipe off any liquid.

6. Do not expose the module to direct sunlight or strong ultraviolet rays for long periods.

7. Do not store the module a temperatures below specifications.Cold can cause the liquid crystals to freeze,lose their elasticity or otherwise suffer damage.

Page 6

8. Do not disassemble the LCD module.Disassembly can cause malfunctions.

9. If you transport the module,do not use packing material that contains epoxy resin(amine)or silicom glue(alcohol or oxime).These materials can release gas that can damage the panel’s polarization.

3-3 Signal Timing Specifications

This is the signal timing required at the input of the User connector. All of the interface signal timing should be satisfied with the following specifications for it’s proper operation.

* Timing Table

DE only Mode

Vertical Frequency:

Notes:

1.) Display position is specific by the rise of DE signal only. Horizontal display position is specified by the rising edge of 1

DCLK after the rise of 1stDE, is displayed on the left edge of the screen. Vertical display position is specified by the rise of DE after a “Low” level period equivalent to eight times of horizontal period. The 1

data corresponding to one horizontal line after the rise the of 1stDE is displayed at the

top line of screen.

3.) If a period of DE “High” is less than 1366 DCLK or less than 768 lines, the rest of the screen displays black.

4.) The display position does not fit to the screen if a period of DE “High” and the effective data period do not synchronize with each other.
