SECTION 1

SELF DIAGNOSIS FUNCTION

The unit in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER lamp will automatically begin to flash. The number of times the lamp flashes translates to a probable source of the problem. A definition of the STANDBY/TIMER lamp flash indicators is listed in the instruction manual for the user's knowledge and reference. If an error symptom cannot be reproduced, the remote commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these problems occur.

1-1. DIAGNOSTIC TEST INDICATORS

When an errors occurs, the STANDBY/TIMER lamp will flash a set number of times to indicate the possible cause of the problem. If there is more than one error, the lamp will identify the first of the problem areas.

Result for all of the following diagnostic items are displayed on screen. No error has occurred if the screen displays a “0”.

1-4. SELF-DIAGNOSTIC SCREEN DISPLAY

For errors with symptoms such as “power sometimes shuts off” or “screen sometimes goes out” that cannot be confirmed, it is possible to bring up past occurrences of failure for confirmation on the screen:

[To Bring Up Screen Test]

In standby mode, press buttons on the remote commander sequentially in rapid succession as shown below:

1-5. HANDLING OF SELF-DIAGNOSTIC SCREEN DISPLAY

Since the diagnostic results displayed on the screen are not automatically cleared, always check the self-diagnostic screen during repairs. When you have completed the repairs, clear the result display to “0”.

Unless the result display is cleared to “0”, the self-diagnostic function will not be able to detect subsequent faults after completion of the repairs.

[Clearing the result display]

To clear the result display to “0”, press button on the remote commander sequentially as shown below when the diagnostic screen is being displayed.

Press “8” button

(It will indicate “CLEAR” on the screen.)

(The “CLEAR” display change to red color.)

Press “-” button

[Quitting Self-diagnostic screen]

To quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.

+B overcurrent (OCP) Occurs when an overcurrent on the +B (135 V) line is detected by Q6303.

If Q6303 go to ON, the voltage to pin 3 of IC002 go to UP. The unit will automatically turn off.

+B overvoltage (OVP) Occurs when an overvoltage on the +B (135 V) line is detected by D6318.

If D6318 go to ON, then voltage to pin 6 of IC002 go to UP. The unit will automatically turn off.

Vertical deflection failure Occurs when an absence of the vertical deflection pulse is detected by

Q5302, Q5303, and D5303. Shut down the power supply.

White balance failure If the RGB levels do not balance or become low level within 5 seconds. This

error will be detected by IC4301. TV will stay on, but there will be no picture.

High voltage protector of Horizontal Deflection Occurs when an overvoltage of horizontal pulse is detected by D5115 and

IC5201. If the voltage of pin 1 of IC5201 goes to High, the voltage to pin 20 of IC4301 go to UP. The unit will automatically turn off.

Audio Protector If the Audio out lines become DC.This error will be detected by Q1202,

Q1204 and Q1203. The unit will automatically turn off.

4-1. HV HOLD-DOWN ADJUSTMENT

1. Connect HV static voltmeter to HV Block.

2. Mount a resistor (R9901 : 43 k , 1/4 W, METAL FILM) at CN5003.

3. Remove CN5002 and connect External Power Supply to

CN5002 1 pin (+135 V) and 2 pin (GND).

4. Turn on the set.

5. Receive the Dot signal and set PICTURE/BRIGHTNESS to minimum.

6. Slowly up the supply voltage from 0 V to 135 V until hold-down circuit works (picture disappear).

7. Read the HV static voltmeter of peak HV voltage. Spec : 33.7 ~ 35.3 kV

8. If Hold-down voltage is less than 33.7 kV then replace R9901 of 43 k with that of 39 k , and check if the voltage is within the spec.

9. If hold-down voltage is over than 35.3 kV then replace R9901 of 43 k with that of 47 k , and check if the voltage is within the spec.

• : Shaded items are fixed data.

• : Though data value is indicated on the screen, it is not used.

• Standard data listed on the Adjustment Item Table are reference values, therefore it may be different for each model and for each

mode.

• Note for Different Data : Those are the standard data values written on the microprocessor. Therefore, the data values of the modes and stored respectively in the memory. In case of a device replacement, adjustment by rewriting the data value is necessary for some items.
