SELF DIAGNOSTIC FUNCTION

The units in this manual contain a self diagnostic function. If an error occurs, the STANDBY (1) indicator will automatically begin to flash. A description of the self-diagnosis function is explained in the instruction manual. The number of times the STANDBY (1) indicator flashes translates to a probable source of the problem. 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. DIAGNOSTIC TEST INDICATORS

When an errors occurs, the STANDBY (1) indicator will flash a set number of times to indicate the possible cause of the problem. If there is more than one error, the indicator will identify the first of the problem areas.

Result for all of the following diagnosis items are displayed on screen. No error has occured if the screen displays a "0".

3. STOPPING THE STANDBY (1) INDICATOR FLASH

Turn off the power switch on the TV main unit or unplug the power cord from the outlet to stop the STANDBY (1) indicator from flashing.

4. SELF-DIAGNOSTIC SCREEN DISPLAY

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

[To Bring Up Screen Test]

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

Display

/ Channel 5 / Volume / Power / TV

Note that this differs from entering the service mode (volume [+]).

The following screen will be displayed indicating the error count.

SELF DIAGNOSTIC

2 : 0 3 : N/A 4 : 0 5 : 1 8 : 0

101 : N/A

Numeral "0" means that no fault was detected. Numeral "1" means the number of a fault occurrence (1 ~ 255).

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-diagnosis 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 buttons on the remote commander subsequent as shown below when the self-diagnostic screen is being displayed.

[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(135V) line is detected by pin 32 of IC001 (A board).

If the voltage of pin 32 of IC001 (A board) is more than 4V, the unit will automatically go to standby.

[V-PROTECT] Occurs when an absence of the vertical deflection pulse is detected by pin 13 of IC001

(A board).

[IK $AKB%] If the RGB levels* do not balance within 15 sec after the power is turned on, this error will

be detected by IC001 (A board). TV will stay on, but there will be 5 times LED blinking.

POWER SUPPLY NG (+5V) for VIDEO PROCESSOR

Occurs when IC001 internal HV protect detects an abnormal H-Pulse (frequency) due to improper power supply to IC001. TV cuts off high voltage power of anode CRT. No picture will be detected. eg: IC602, IC604 go faulty.

* (Refers to the RGB levels of the AKB detection Ref pulse that detects IK.)

• REMOVAL OF ANODE-CAP

Note:

• After removing the anode, short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT shield or carbon paint on the CRT.

• REMOVING PROCEDURES

1 Turn up one side of the rubber cap in the direction

indicated by the arrow A.

2 Using a thumb pull up the rubber cap firmly in the di-

rection indicated by the arrow B.

3 When one side of the rubber cap is separated from

the anode button, the anode-cap can be removed by

anode button

turning up the rubber cap and pulling it up in the direction of the arrow C.

• HOW TO HANDLE AN ANODE-CAP

1 Do not damage the surface of anode-caps with

sharp shaped objects.

2 Do not press the rubber too hard so as not to

damage the inside of anode-cap. A metal fitting called the shatter-hook terminal is built into the rubber.

3 Do not turn the foot of rubber over too hard.

The shatter-hook terminal will stick out or damage the rubber.

SET-UP ADJUSTMENTS

• The following adjustments should be made when a complete realignment is required or a new picture tube is installed.

Perform the adjustments in the following order :

1. Beam Landing

2. Convergence

3. Focus Set the controls as follows unless otherwise noted:

VIDEO model ..................................................... Standard

PICTURE control .................................................. normal

BRIGHTNESS control .......................................... normal

4. Screen(G2)

5. White Balance

Note : Test Equipment Required.

1. Pattern Generator

2. Degausser

3. DC Power Supply

4. Digital Multimeter

5. Oscilloscope

......................................................................................................................................................................................................................

Preparation :

• In order to reduce the influence of geomagnetism on

the set's picture tube, face it east or west.

• Switch on the set's power and degauss with the

degausser.

2-1. BEAM LANDING

Picture Mode: DYNAMIC

1. Input a white signal with the pattern generator.

Contrast Brightness

}

normal

2. Set the pattern generator raster signal to a green

raster.

3. Move the deflection yoke to the rear and adjust with

purity control so that the green is at the center and the blue and the red take up equally sized areas on each side. (See Figures 2-1 through 2-4.)

4. Move the deflection yoke forward and adjust so that

the entire screen is green. (See Figure 2-1.)

5. Switch the raster signal to blue then to red and verify

the condition.

6. When the position of the deflection yoke has been

decided fasten the deflection yoke with the screws and DY spacers.

7. If the beam does not land correctly in all the corners,

use a magnet to adjust it. (See Figure 2-4.)

Purity control corrects this area.
