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 INDICAT ORS

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”.

• Power is shut down shortly, after this return back to normal.

• Detect Micro latch up.

Note 1: If a + B overcurrent is detected, stoppage of the vertical deflection is detected simultaneously.

The symptom that is diagnosed first by the microcontroller is displayed on the screen.

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 occurances 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:

[Screendisplay] / channel [5] / Sound volume [-] / Power ON

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

Self-Diagnosis screen display

SELF DIAGNOSTIC

002 : 000 003 : 000 004 : 000 005 : 001

101 : 000

Numeral "0" means that no fault has been detected.

Numeral "1" means a fault has been detected.

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 buttons on the remote commander sequentially as shown below when the diagnostic screen is being displayed.

Channel [8] / 0

[Quitting Self-diagnostic screen]

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

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 direction 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 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

KV-XS29N90/XS29N93

RM-914

• 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.

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

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

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

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

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.

Perform the adjustments in the following order :

1. Beam Landing

2. Convergence

3. Focus

4. White Balance Note : Test Equipment Required.

1. Color-bar/Pattern Generator

2. Degausser

3. Oscilloscope

3-1. BEAM LANDING

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

2. Position neck assy as shown in Fig3-2.

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 3-1 through 3-4.)

5. Move the deflection yoke forward and adjust so that the entire screen is green. (See Figure 3-2.)

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 3-5.)
