SECTION 1

PRECAUTION

1.1 SAFETY PRECAUTIONS

(1) 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. Replacement parts must be identical to those used in the original circuits. Service should be performed by qualified personnel only.

(2) 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 damage resulting therefrom.

(3) 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 ( ) 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 of Service manual may cause shock, fire, or other hazards.

(4) Don't short between the LIVE side ground and

ISOLATED (NEUTRAL) side ground or EARTH side ground when repairing.

Some model's power circuit is partly different in the GND. The difference of the GND is shown by the LIVE: ( ) side GND, the ISOLATED (NEUTRAL): ( ) side GND and EARTH: ( ) side GND. Don't short between the LIVE side GND and ISOLATED (NEUTRAL) side GND or EARTH side GND and never measure the LIVE side GND and ISOLATED (NEUTRAL) side GND or EARTH side GND at the same time with a measuring apparatus (oscilloscope etc.). If above note will not be kept, a fuse or any parts will be broken.

(5) 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, those components that indicate evidence of overheating should be replaced. Always use the manufacturer's replacement components.

(6) Isolation 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, screw heads, earphone jack, control shafts, etc.) to be sure the product is safe to operate without danger of electrical shock.

a) 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 3000V 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 (r.m.s.) to an appliance rated 200V or more, for a period of one second.) This method of test requires a test equipment not generally found in the service trade.

b) 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 path to the chassis, to a known good earth ground (water pipe, etc.). Any leakage current must not exceed 0.5mA AC (r.m.s.). However, in tropical area, this must not exceed 0.2mA 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 having 1000Ω per volt or more sensitivity in the following manner. Connect a 1500Ω 10W resistor paralleled by a 0.15µF AC-type capacitor

between an exposed metal part and a known good earth ground (water pipe, etc.). Measure the AC voltage across the resistor with the AC voltmeter. Move the resistor 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 0.75V AC (r.m.s.). This corresponds to

0.5mA AC (r.m.s.). However, in tropical area, this must not exceed 0.3V AC (r.m.s.). This corresponds to 0.2mA AC (r.m.s.).

(2) Alterations of the design or circuitry of the product should

(3) Many electrical and mechanical parts in the product have

special safety-related characteristics. These characteristics are often not evident from visual inspection nor can the protection afforded by them necessary 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 ( ) on the Parts List in the 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 of Service Manual may cause shock, fire, or other hazards.

(4) The leads in the products are routed and dressed with ties,

clamps, tubing’s, barriers and the like to be separated from live parts, high temperature parts, moving parts and / or sharp edges for the prevention of electric shock and fire hazard. When service is required, the original lead routing and dress should be observed, and it should be confirmed that they have been returned to normal, after reassembling.

safety standards.

(4) It is essential that safety critical components are

replaced by approved parts.

(5) If mains voltage selector is provided, check setting for

local voltage.

1.3 HANDLING LCD PANEL

1.3.1 PRECAUTION FOR TRANSPORTATION

When transporting the display unit, pressure exerted on the internal LCD (Liquid Crystal Display) panel due to improper handing (such as tossing and dropping) may cause damages even when the unit is carefully packed. To prevent accidents from occurring during transportation, pay careful attention prior to delivery such as through exchanging the handing instructions to transporters. Ensure that the following requirements are met during transportation, as the LCD panel of this unit is made of glass and therefore fragile.

(1) Avoid vibrations and impacts

The unit may be broken if it is toppled sideways even when properly packed. Ensure that the unit is carried by at least 2 persons and pay careful attention not to exert any vibration or impact on it.

(2) Do not place equipment lay a LCD panel on its side.

A LCD panel should always be placed upright during both transportation and safekeeping. Don't lay it on its side. The panel of a LCD panel is very fragile to the impact in the horizontal direction. When a car carries a LCD panel, load it on board the car in parallel with the moving direction of the car. Don't lay several LCD panels one on top another. During safekeeping, don't lay more than two LCD panels one on top another even if they are kept upright.

1.3.2 OPTICAL FILTER (FRONT FILTER)

Avoid placing the unit under direct sunlight over a prolonged period of time. This may cause the optical filter to deteriorate in quality and color. Clean the filter surface by wiping it softly lightly with outing flannels a soft and lightly fuzz cloth (such a flannel). Do not use solvents such as benzene or thinner to wipe the filter surface. This may cause the filter to deteriorate in quality or the coating on the surface to come off. As the filter surface is fragile. Do not scratch or hit it with hard materials.

1.3.3 NOTES PRECAUTIONS FOR REPLACEMENT OF EXTERIOR PARTS

Take note of the following when replacing exterior parts (back REAR COVER, FRONT PANEL, OPTICAL FILTER): Do not exert pressure on the front of the LCD panel (glass surface). Pay careful attention not to scratch or stain the front of the LCD panel (surface) with hands. When replacing exterior parts, the front of the LCD panel should be placed facing downward. Place a met, etc. underneath to avoid causing scratched to the front surface. However, never use materials that are too soft (such as blanket cloth). If replacement is made with the LCD panel surface facing downward and in contact with the blanket, pressure may be exerted on the LCD panel, thus causing damages to it.

TROUBLESHOOTING

5.1 SELF-DIAGNOSIS FUNCTION

5.1.1 OUTLINE

This model has a "Self-diagnosis function" which checks the operation state of the circuits and temperature inside the set, and informs us of a failure and memorize it when a failure occurs. Diagnosis is performed when the power is turned on, and information input to the main microcomputer is monitored at all time. The diagnosis is displayed on the screen and LED flashing. Failure detection is based on input state of I control lines connected to the main microcomputer.

5.1.2 ENTERING SELF-DIAGNOSIS BLOCK

(1) Enter the SERVICE MODE. (Fig. 1) (2) Select DIAGNOSIS BLOCK in the second page (2/2) and

press the [] key. (Fig. 2)

Failure history can be counted up to 9 times for each item. When the number exceeds 9, the display will remain as 9. Failure history will be stored in the memory unless it has been deleted. In addition to circuit failures (abnormal operation), the following cases may also be diagnosed as abnormal and displayed and counted as "X".

(1) Temporary defective transmissions across circuits due to

pulse interruptions

(2) Misalignment in the on/off timing of power for I

C bus (Vcc)

when turning on/off the power. If a failure is expected to reoccur, clear (reset) the failure history to make the unit record the new diagnosis results.
