SECTION 1PRECAUTION
1.1 SAFETY PRECAUTIONS(1) The design of this product contains special hardware,
many circuits and components specially for safetypurposes. For continued protection, no changes should bemade to the original design unless authorized in writing bythe manufacturer. Replacement parts must be identical tothose used in the original circuits. Service should beperformed by qualified personnel only.
(2) Alterations of the design or circuitry of the products shouldnot be made. Any design alterations or additions will voidthe manufacturer's warranty and will further relieve themanufacturer of responsibility for personal injury orproperty damage resulting therefrom.
(3) Many electrical and mechanical parts in the products havespecial safety-related characteristics. Thesecharacteristics are often not evident from visual inspectionnor can the protection afforded by them necessarily beobtained by using replacement components rated forhigher voltage, wattage, etc. Replacement parts whichhave these special safety characteristics are identified inthe parts list of Service manual. Electrical componentshaving such features are identified by shading on theschematics and by ( ) on the parts list in Servicemanual. The use of a substitute replacement which doesnot have the same safety characteristics as therecommended replacement part shown in the parts list ofService manual may cause shock, fire, or other hazards.
(4) Don't short between the LIVE side ground andISOLATED (NEUTRAL) side ground or EARTH sideground when repairing. Some model's power circuit is partly different in the GND.The difference of the GND is shown by the LIVE : ( ) sideGND, the ISOLATED (NEUTRAL) : ( ) side GND andEARTH : ( ) side GND. Don't short between the LIVE side GND and ISOLATED(NEUTRAL) side GND or EARTH side GND and nevermeasure the LIVE side GND and ISOLATED (NEUTRAL)side GND or EARTH side GND at the same time with ameasuring apparatus (oscilloscope etc.). If above note willnot 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 leaddress in the high voltage circuit area. Where a short circuithas occurred, those components that indicate evidence ofoverheating should be replaced. Always use themanufacturer's replacement components.
(6) Isolation Check (Safety for Electrical Shock Hazard) After re-assembling the product, always perform anisolation 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 operatewithout danger of electrical shock.
a) Dielectric Strength Test The isolation between the AC primary circuit and all metalparts exposed to the user, particularly any exposed metalpart having a return path to the chassis should withstand avoltage of 3000V AC (r.m.s.) for a period of one second. (.. . . Withstand a voltage of 1100V AC (r.m.s.) to anappliance rated up to 120V, and 3000V AC (r.m.s.) to anappliance rated 200V or more, for a period of one second.) This method of test requires a test equipment not generallyfound in the service trade.
b) Leakage Current Check Plug the AC line cord directly into the AC outlet (do not usea line isolation transformer during this check.). Using a"Leakage Current Tester", measure the leakage currentfrom each exposed metal part of the cabinet, particularlyany exposed metal part having a return path to the chassis,to a known good earth ground (water pipe, etc.). Anyleakage 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 notuse a line isolation transformer during this check.). Usean AC voltmeter having 1000 per volt or moresensitivity in the following manner. Connect a 150010W resistor paralleled by a 0.15F AC-type capacitorbetween an exposed metal part and a known good earthground (water pipe, etc.). Measure the AC voltageacross the resistor with the AC voltmeter. Move theresistor connection to each exposed metal part,particularly any exposed metal part having a return pathto the chassis, and measure the AC voltage across theresistor. Now, reverse the plug in the AC outlet andrepeat each measurement. Any voltage measured mustnot exceed 0.75V AC (r.m.s.). This corresponds to0.7mA AC (r.m.s.). However, in tropical area, this must not exceed 0.35VAC (r.m.s.). This corresponds to 0.3mA AC (r.m.s.).

1.2.4 NOTES ON HANDLINGWhen taking the unit out of a packing case, do not grasp theupper part of the unit. If you take the unit out while grasping theupper part, the LCD PANEL may be damaged because of apressure. Instead of grasping the upper part, put your hands onthe lower backside or sides of the unit.
1.3 HANDLING LCD PANEL1.3.1 PRECAUTIONS FOR TRANSPORTATIONWhen transporting the unit, pressure exerted on the internal LCDpanel due to improper handling (such as tossing and dropping)may cause damages even when the unit is carefully packed. Toprevent accidents from occurring during transportation, paycareful attention before delivery, such as through explaining thehandling instructions to transporters.Ensure that the following requirements are met duringtransportation, as the LCD panel of this unit is made of glass andtherefore fragile:
(1) USE A SPECIAL PACKING CASE FOR THE LCD PANELWhen transporting the LCD panel of the unit, use a specialpacking case (packing materials). A special packing caseis used when a LCD panel is supplied as a service sparepart.
(2) ATTACH PROTECTION SHEET TO THE FRONTSince the front (display part) of the panel is vulnerable,attach the protection sheet to the front of the LCD panelbefore transportation. Protection sheet is used when a LCDpanel is supplied as a service spare part.
(3) AVOID VIBRATIONS AND IMPACTSThe unit may be broken if it is toppled sideways even whenproperly packed. Continuous vibration may shift the gap ofthe panel, and the unit may not be able to display imagesproperly. Ensure that the unit is carried by at least 2persons and pay careful attention not to exert any vibrationor impact on it.
(4) DO NOT PLACE EQUIPMENT HORIZONTALLYEnsure that it is placed upright and not horizontally duringtransportation and storage as the LCD panel is veryvulnerable to lateral impacts and may break. Duringtransportation, ensure that the unit is loaded along thetraveling direction of the vehicle, and avoid stacking themon one another. For storage, ensure that they are stackedin 2 layers or less even when placed upright.
1.3.2 OPTICAL FILTER (ON THE FRONT OF THE LCD PANEL)(1) Avoid placing the unit under direct sunlight over a
prolonged period of time. This may cause the optical filterto deteriorate in quality and COLOUR.
(2) Clean the filter surface by wiping it softly and lightly with asoft and lightly fuzz cloth (such as outing flannel).
(3) Do not use solvents such as benzene or thinner to wipe thefilter surface. This may cause the filter to deteriorate inquality or the coating on the surface to come off. Whencleaning the filter, usually use the neutral detergent dilutedwith water. When cleaning the dirty filter, use water-dilutedethanol.
(4) Since the filter surface is fragile, do not scratch or hit it withhard materials. Be careful enough not to touch the frontsurface, especially when taking the unit out of the packingcase or during transportation.
1.3.3 PRECAUTIONS FOR REPLACEMENT OF EXTERIORPARTS
Take note of the following when replacing exterior parts (REARCOVER, FRONT PANEL, etc.):
(1) Do not exert pressure on the front of the LCD panel (filtersurface). It may cause irregular COLOUR.
(2) Pay careful attention not to scratch or stain the front of theLCD panel (filter surface) with hands.
(3) When replacing exterior parts, the front (LCD panel) shouldbe placed facing downward. Place a mat, etc. underneathto avoid causing scratches to the front (filter surface).

2.4 TECHNICAL INFORMATION2.4.1 LCD PANELThis unit uses the flat type panel LCD (Liquid Crystal Display) panel that occupies as little space as possible, instead of theconventional CRT (Cathode Ray Tube), as a display unit.Since the unit has the two polarizing filter that are at right angles to each other, the unit adopts "normally black" mode, where lightdoes not pass through the polarizing filter and the screen is black when no voltage is applied to the liquid crystals.
2.4.1.1 SPECIFICATIONSThe following table shows the specifications of this unit.
2.4.1.2 PIXEL FAULTThere are three pixel faults - bright fault, dark fault and flicker fault - that are respectively defined as follows.
BRIGHT FAULTIn this pixel fault, a cell that should not light originally is lighting on and off.For checking this pixel fault, input ALL BLACK SCREEN and find out the cell that is lighting on and off.
DARK FAULTIn this pixel fault, a cell that should light originally is not lighting or lighting with the brightness twice as brighter as originally lighting.For checking this pixel fault, input 100% of each R/G/B colour and find out the cell that is not lighting.
FLICKER FAULTIn the pixel fault, a cell that should light originally or not light originally is flashing on and off.For checking this pixel fault, input ALL BLACK SCREEN signal or 100% of each RGB colour and find out the cell that is flashing onand off.

SECTION 5TROUBLESHOOTING
5.1 SELF CHECK FEATURE5.1.1 OUTLINEThis unit comes with the "Self check" feature, which checks theoperational state of the circuit and displays/saves it duringfailure.Diagnosis is performed when power is turned on, andinformation input to the main microcomputer is monitored at alltime.Diagnosis is displayed in 2 ways via screen display and LEDflashes. Failure detection is based on input state of I2C bus andthe various control lines connected to the main microcomputer.
5.1.2 HOW TO ENTER THE SELF CHECK MODE(1) Press the [DISPLAY] key and [MUTING] key
simultaneously, then enter the SERVICE MODE.(2) Press the [2] key then enter the SELF CHECK MODE.
NOTE:When a number key other than the [2] key is pressed in theSERVICE MODE screen, the other relevant screen may bedisplayed.This is not used in the SELF CHECK MODE. Press the[MENU] key to return to the MAIN MENU SCREEN.
5.1.3 HOW TO EXIT THE SELF CHECK MODETo Save Failure History:Turn off the power by unplugging the AC power cord plug whenin the Self check display mode.To Clear (Reset) Failure History: Turn off the power by pressing the [POWER] key on the remotecontrol unit when in the Self check display mode.
5.1.4 FAILURE HISTORYFailure history can be counted up to 9 times for each item. Whenthe number exceeds 9, display will remain as 9. Failure historywill be stored in the memory unless it has been deleted.
NOTE:Only SYNC (with/without sync signals) will be neither countednor stored.
5.1.5 POINTS TO NOTE WHEN USING THE SELF CHECKFEATURE
In addition to circuit failures (abnormal operation), the followingcases may also be diagnosed as "Abnormal" and counted.
(1) Temporary defective transmissions across circuits due topulse interruptions.
(2) Misalignment in the on/off timing of power for I2C bus (Vcc)when turning on/off the main power.
Therefore, turn on the main power, and then wait for about 3seconds before starting Self check. If recurrences are expected, ensure to clear (reset) the failurehistory and record the new diagnosis results.
