SELF DIAGNOSIS FUNCTION

The units in this manual contain a self-diagnosis 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. DIAGNOSIS 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”.

Symptoms

• Power does not turn on.

• No power is supplied to

• AC power supply is faulty.

• Power does not turn on.

• Load on power line is
shorted.

• Has entered standby state
after horizontal raster.

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 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 (volume [+]).

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

KV-HW21P80A

5. HANDLING OF SELF-DIAGNOSTIC SCREEN DISPLAY

Since the diagnosis 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 sequentially as shown below when the self­diagnostic 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.

[+B overcurrent $OCP%] Occurs when an overcurrent on the +B(135) line is detected by Q500. If Q500 go to

ON and the voltage to pin 50 of IC301 more than 3.5V when V.SYNC is more than
seven verticals in a period, the unit will automatically turn off.

[Vertical deflection stopped] Occurs when an absence of the vertical deflection pulse is detected by Pin 17 and

IC001 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 IC301. TV will stay on, but there will be no picture.

Note:

• The picture tube is upside-down and the position for the anode cap and tension springs are changed accordingly.

• Please make sure the TV set is not in standing position before removing necessary CRT support located on bottom

right and left.

1) Place the TV set with the CRT face down on a cushion jig.

2) Remove the rear cover.

3) Unplug all inder connecting leads from the Deflection Yoke, Degaussing Coil and CRT grounding strap.

• 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.

SECTION 2

SET-UP ADJUSTMENTS

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. Pattern Generator

2. Degausser

3. Oscilloscope

Purity control

2-1. BEAM LANDING

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

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

3. 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 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.)

horizontal convergence with the H.STAT variable resistor
and the V.STAT magnet in the manner given below.

NOTE:

•

Bold item :- are fixed data

•

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.
