SECTION 1 PRECAUTION
1.1 SAFETY PRECAUTIONS [EXCEPT FOR UK] (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 ) side GND and GND, the ISOLATED (NEUTRAL) : ( 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) 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). (6) 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-Ray 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 approved by the manufacturer of the complete product. (7) Do not check high voltage by drawing an arc. Use a high voltage meter or a high voltage probe with a VTVM. Discharge the picture tube before attempting meter connection, by connecting a clip lead to the ground frame and connecting the other end of the lead through a 10k 2W resistor to the anode button. (8) 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. (9) 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 1000 ohms per volt or more sensitivity in the following manner. Connect a 1500 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.).

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·fs, 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 re-assembling. WARNING (1) (2) (3) (4) (5) The equipment has been designed and manufactured to meet international safety standards. It is the legal responsibility of the repairer to ensure that these safety standards are maintained. Repairs must be made in accordance with the relevant safety standards. It is essential that safety critical components are replaced by approved parts. If mains voltage selector is provided, check setting for local voltage.

PRECAUTIONS REGARDING PDP 1.4.4 OPTICAL FILER (PANEL 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 as flannel). Do not use solvents such as benzine 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 Tthe filter surface is fragile., Ddo not scratch or hit it with hard materials. 1.4.5 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 PDP (glass surface). · Pay careful attention not to scratch or stain the front of the PDP (surface) with hands. · When replacing exterior parts, the front of the PDP should be placed facing downward. Place a mat, etc. underneath to avoid causing scratches to the front surface. However, never use materials that are too soft (such as blanket cloth). If replacement is made with the PDP surface facing downward and in contact with the blanket, pressure may be exerted on the PDP, thus causing damages to it.

1.4.1 PRECAUTIONS DURING NOTES FOR TRANSPORTATION When transporting the display unit, pressure exerted on the internal PDP (Pplasma Ddisplay Ppanel) due to improper handling (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 explaining the handling instructions to transporters. Ensure that the following requirements are met during transportation, as the PDP 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 horizontally Ensure that it is placed upright and not horizontally during transportation and storage as the PDP is very vulnerable to lateral impacts and may break easily under such circumstances. During transportation, ensure that the unit is loaded along the traveling direction of travel of the vehicle, and avoid stacking them on one another. For storage, ensure that they are stacked in 2 layers or less even when placed upright. 1.4.2 RESIDUAL IMAGE / BURN-IN ON SCREEN Like CRTs, "burn-in" may occur when a same image is continuously displayed over an extended period of time. As Tthis may also shorten the life span of the PDP. Therefore, turn off the display when not in use, scroll the screen, make use of screen-savers, or allow even distribution on the display by inverting the brightness, switching to complementary colors or inserting animated images at periodic intervals. As burn-in is more likely to occur with high brightness and contrast settings, try to use neutral gradations or medium tone colors. Burn-in does not occur in the case of animated images. When switching to another image after continuous display of the previous image, residual images may become prominent, as luminance in a part of the display is higher than the other parts. This is not a defect but is because due to the discharge surface of the lighted portion has becomebeing relatively activated and its luminance higher than the unlighted parts. 1.4.3 INFRARED RAYS Near Near-infrared rays (800nm to 1000nm) are emitted from the front of the panel, and this may give rise to glitchescause malfunctions in infrared remote controls or communication systems placed near it. In this case, avoid direct infrared rays (and reflected rays in some cases) from the screen by either changing the direction of the unit or other infrared systems or securing a longer keeping a distance from the screen.

2.3.1.2 PIXEL DEFECTS Though PDP is made by means of ultra precise technology, there are cases whereby not all pixels (cell) will function properly. In some cases, there may be defective pixels that do not light at all or the ones that always light on. There are 3 types of Pixel defects, [Bright Dot Defects], [Dark Dot Defects] and [Flicker Dot Defects], as defined respectively in the following: (1) Bright Dot Defects Bright dot defect is a pixel cell that lights though it should not light. The presence of bright dot defects can be confirmed by inputting a full black signal (pattern). (2) Dark Dot Defects Dark dot defect is a pixel cell that does not light, though it should light. The presence of dark dot defects can be confirmed by inputting a 100% full white signal (pattern). (3) Flicker Dot Defects Flicker dot defect is a pixel cell that blinks though it should light or not light. The presence of flicher dot defects can be confirmed by inputting a full black signal (pattern).
