SELF DIAGNOSTIC FUNCTION

The units 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. 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 occured if the screen displays a “0”.

•REMOVAL OF ANODE-CAP

Note:

Please remove necessary CRT support located on top left, top right, prior to removing the CRT.

– 27 –

NOTE : After removing the anode, shor t 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 direction indicated by the arrow b.

Anode Button

3 When one side of the rubber cap is separated from the anode button, the anode-cap

can be removed by 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.

ADVANCE OPERATION

3-1. "RESET" FUNCTION

1. Purpose

If a customer faces some setting problem that cannot be solved, using the "RESET" function some items will be reset to its original setting (shipment condition)

2. How to Operate

The way to access to the "RESET" Function:-

a) By pressing "MENU" button or "SELECT" button (for non-menu models) on the Front Key Input and

hold it down for 5 seconds.

3. Subsequent of Operation

Sequential to the resetting operation (either methods being used in No. 2), TV set would shut down once and automatically turn on again. The power-off duration is expected to be about 500msec. An OSD message, "RESET" tentatively will be displayed for 10 sec after IK status gets stable. As a result, some items will be reset to an initial condition (shipment condition) wheareas some other remains at the last selection by user.

SET-UP ADJUSTMENTS

KV-XA25M93/XA29M80

RM-954

• The following adjustments should be made when a complete

realignment is required or a new picture tube is installed.

• These adjustments should be performed with rated power

supply voltage unless otherwise noted.

Perform the adjustments in the following order :

1. Beam Landing

2. Convergence

3. Focus

4. White Balance

Controls and switches should be set as follows unless otherwise noted:

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

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

Note : Test Equipment Required.

1. Pattern Generator

2. Degausser

3. Oscilloscope

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

Purity control

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.

4-1. BEAM LANDING

1. Input a white signal with the pattern generator. Contrast Brightness

2. Position neck assy as shown in Fig4-1.

3. Set the pattern generator raster signal to a green raster.

4. Move the deflection yoke to the rear and adjust with the 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 4-2 through 4-4.)

5. Move the deflection yoke forward and adjust so that the entire screen is green. (See Figure 4-2.)

6. Switch the raster signal to blue, then to red and verify the condition.

7. When the position of the deflection yoke has been decided, fasten the deflection yoke with the screws and DY spacers.

8. If the beam does not land correctly in all the corners, use a magnet to adjust it.

(See Figure 4-5.)

1. (Moving horizontally), adjust the H.STAT control so that the red, green and blue dots are on top of each other at the center of the screen.

2. (Moving vertically), adjust the V.STAT magnet so that the red, green and blue dots are on top of each other at the center of the screen.

3. If the H.STAT variable resistor cannot bring the red, green and blue dots together at the center of the screen, adjust the horizontal convergence with the H.STAT variable resistor and the V.STAT magnet in the manner given below. (In this case, the H.STAT variable resistor and the V.STAT magnet influence each other, so be sure to perform adjustments while tracking.)
