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 that 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) Use isolation transformer when hot chassis.

The chassis and any sub-chassis contained in some products are connected to one side of the AC power line. An isolation transformer of adequate capacity should be inserted between the product and the AC power supply point while performing any service on some products when the HOT chassis is exposed.

(5) 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 with a measuring apparatus (oscilloscope etc.) the LIVE side GND and ISOLATED(NEUTRAL) side GND or EARTH side GND at the same time. If above note will not be kept, a fuse or any parts will be broken.

(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) 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).

(8) 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 10kΩ 2W resistor to the anode button.

(9) 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.

(10) 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, screwheads, 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 1100V AC (r.m.s.) for a period of one second.

(. . . . Withstand a voltage of 1100V AC (r.m.s.) to an appliance rat-

ed 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 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.).

4.6.4 DEFLECTION & CONVERGENCE ADJUSTMENT

• The adjustment using the remote control unit is made on the basis of the initial setting values.

• The setting values which adjust the screen to the optimum condition can be different from the initial setting values.

• At first the adjustment in FULL mode should be done, then the data for the other ASPECT mode is corrected in the respective value at the same time.

4.6.4.1 FLOWCHART OF ADJUSTMENT

CAUTION:

All adjustments of the DEFLECTION circuit for this model should be carried out under the status without convergence operation. To enter the mode without convergence operation, select 1.PICTURE/SOUND and change the data in the setting item F62 from 0 to 1. (For details, please refer to the adjustment of DEFLECTION.) As a result, you can get the screen as shown in bellow figure. Adjust the DEFLECTION circuit in order of the steps indicated by the downward arrows.

NOTE:

When every adjustment of the DEFLECTION circuit has completed, start the adjustment of convergence.

AUTO CONVERGENCE (SUPER FOCUS) PRESET

AUTO CONVERGENCE PRESET is a work in which you store (memorize) an optimum reference CONVERGENCE in SUPER FOCUS operation in the unit. At the factory, this PRESET has been carried out and memorized in the unit after adjusting CONVERGENCE. However, PRESET will be invalid when the servicing is carried out in accordance with the following conditions. In this case, it is necessary to execute PRESET again.

CONDITIONS THAT RESET IS EXECUTED

(1) When the data is memorized with the [MUTING]

key on SERVICE MENU 6.CONVER A regardless of the change of data (CPA, CCA, CDA and CBA).

(2) When the data is memorized with the [MUTING]

key on SERVICE MENU 7.CONVER B regardless of CONVERGENCE adjustment.

NOTE FOR PRESET

• It is required that you must execute PRESET when CONVERGENCE has been properly adjusted because the CONVERGENCE will be a reference to SUPER FOCUS.

• When SENSOR around the SCREEN is replaced to new one, it is also necessary to execute PRESET. In this case, perform RESET according to the steps 1 or 2, then execute PRESET again.

HOW TO EXECUTE PRESET

When executing SUPER FOCUS with AUTO on CONVERGENCE of the USER MENU or SUPER FOCUS button on the FRONT CONTROL, you can execute PRESET automatically when RESET is applied. In this case, a dimmed block will be displayed in the center of the screen. (When SUPER FOCUS is operated, a crossshape pattern will be displayed in the center of the screen.)

NOTE :

When a unicolor block in the center of the screen flashes on and off at PRESET or SUPER FOCUS, it means that the input from SENSOR is not normal (input level is too low). In this case, make sure that SENSOR receives enough light from the backside.

• Not receives enough light

It is necessary to readjust RASTER CENTER, H/V SIZE and CONVERGENCE.

• Receives enough light

Failure of the sensor or defects of detection route (circuit).

TROUBLESHOOTING

5.1 SELF-DIAGNOSIS FUNCTIONS

• This model has self-check functions that inform of the failure of the TV by detecting abnormality.

• Operational state is always monitored and the identified is memorized on the record. Therefore, diagnosis may be prevented against expectations if "NG" are indicated in many items. When recurrence of symptoms can be predicted, erase (reset) the history of failure and allow the unit to again record the results of diagnosis.

5.1.1 HOW TO ENTER THE SELF-DIAGNOSIS MODE

(1) Set the < SLEEP TIMER 30 MIN. > with [SLEEP TIMER]

key. (Fig.1)

(2) During the < SLEEP TIMER 30 MIN. > display, press

[DISPLAY] key and [VIDEO STATUS] key at the same time. (3) Then < TEST MODE > screen is displayed. (Fig.2) (4) Press [ 4 ] key then < SELF-CHECK > screen is appear.

(Fig.3)

SLEEP TIMER 30 MIN.

5.1.2 HOW TO EXIT FROM THE SELF-DIAGNOSIS MODE

• With initialization By using the remote control unit, turn the power off. At this time, the failure record is cleared.

• With not initialization

(1) Take off the AC plug from the wall outlet. At this time, the

failure record is not cleared.

(2) Press the [BACK] key the SELF-CHECK screen return to

TEST MODE screen.

5.1.3 EXPLANATION FOR ACTIVATION OF SELF-DIAGNOSIS

FUNCTIONS

• The latest failure is stored on the record at the end. The failure record for each check item is counted to the number of 9 at the maximum, When more than 9 failures are stored on the record, the counter remains stopped at 9.

• SYNC is neither counted nor stored in memory.

• Because of the timing of Vcc start-up and shut-down of the IC connecting to the I

C bus during which the power is turned on and off, the operation may be interpreted as an error. In order to avoid the misinterpretation, the self-check functions should be started at about 3 seconds after the power is turned on.

5.1.4 SELF-CHECK DISPLAY LED

The self-check results are shown on the following LED display. Method of indication when the raster is not displayed.

Each failure is shown by turning POWER LED on and off at specified intervals.

• For X-ray radiation protection, B1 over-current protection, low B short protection and CRT neck broken protection, the power of the TV is turned off if NG is detected. Immediately after the power is turned off, POWER LED will be turning on and off. When the power is turned off, you cannot turn the power on again until the AC plug is taken out and put in again.
