4. Alignment and Adjustments

4-1 Preadjustment

4-1-1 Factory Mode

1. Do not attempt these adjustments in the Video
Mode.

2. The Factory Mode adjustments are necessary
when either the EEPROM (IC902) or the CRT
is replaced.

3. Do not tamper with the “Adjustment” screen
of the Factory Mode menu. This screen is
intended only for factory use.

4-1-2 When EEPROM (IC902) Is Replaced

1. When IC902 is replaced all adjustment data
revert to initial values. It is necessary to
re-program this data.

2. After IC902 is replaced, warm up the TV for
10 seconds.

4-1-3 When CRT Is Replaced

1. Make the following adjustments AFTER set­ting up after setting up purity and conver­gence :

White Balance
Sub-Brightness
Vertical Center
Vertical Size
Horizontal Size
Fail Safe (This adjustment must be the last
step).

2. If the EEPROM or CRT is replaced, set PVAto
40 (factory mode) and set SC as follows.

14 inch : 0
20 inch : 9

21 inch : 9

4-2 Factory/Service Mode

4-2-1 Procedure for the “Adjustment” Mode

1. This mode uses the standard remote control.
The Service Mode is activated by entering the
following remote-control sequence :

(1) DISPLAY→FACTORY.
(2) STAND-BY→ DISPLAY→ MENU→ MUTE

→POWER ON.

2. The “SERVICE (FACTORY)” message will be
displayed. The Service Mode has four compo­nents: ADJUST, OPTION and Reset.

3. Access the Adjustment Mode by pressing the
“VOLUME” keys ( Up or Down). The adjust­ment parameters are listed in the accompany­ing table, and selected by pressing the CHAN­NEL keys (▲ ,▼).

4. Selection sequences for the all system:

DOWN or UP key:
SCT>SBT>BLR>BLB>RG>GG>BG>VSL>
VS>VA>HS>SC>SDL>STT>SSP>PDL>
NDL>PSR>NSR>AGC>VOL>LCO>TXP

5. The VOLUME keys increase or decrease the
adjustment values (stored in the
non-volatile memory) when Adjustment Mode
is cancelled.

6. Cancel the Adjustment Mode by re-pressing
the “FACTORY” or “Power OFF” keys.

4-2-2 Main Adjustment Parameter

NOTE : PVS,PVA, PHS, parameters must be aligned using the 50Hz vertical-field rates.

4-3 Other Adjustments

4-3-1 General

1. Usually, a color TV needs only slight touch­up adjustment upon installation. Check the
basic characteristics such as height, horizontal
and vertical sync and focus.

2. The picture should have good black and white
details. There should be no objectionable
color shading; if color shading is present, per­form the purity and convergence adjustments
described below.

3. Use the specified test equipment or its equiva­lent.

4. Correct impedance matching is essential.

5. Avoid overload. Excessive signal from a sweep
generator might overload the front-end of the
TV. When inserting signal markers, do not
allow the marker generator to distort test
results.

6. Connect the TV only to an AC power source
with voltage and frequency as specified on the
backcover nameplate.

7. Do not attempt to connect or disconnect any
wires while the TV is turned on. Make sure
that the power cord is disconnected before
replacing any parts.

8. To protect against shock hazard, use an isola­tion transformer.

4-3-2 Automatic Degaussing

A degaussing coil is mounted around the pic­ture tube, so that external degaussing after
moving the TV should be unnecessary. But
the receiver must be properly degaussed upon
installation.

The degaussing coil operates for about 1 sec­ond after the power is switched ON. If the set
has been moved or turned in a different direc­tion, disconnect its AC power for at least 30
minutes.

If the chassis or parts of the cabinet become
magnetized, poor color purity will result. If
this happens, use an external degaussing coil.
Slowly move the degaussing coil around the
faceplate of the picture tube and the sides and
front of the receiver. Slowly withdraw the coil
to a distance of about 6 feet before removing
power.

4-2-4 RESET

The Reset Mode is used during factory inspection.
Function Reset:

1. Picture Custom

2. Auto Volume Off

3. Color System Auto (option)

4. Sound System D/K (option)

5. Blue Screen Off

6. Low Noise AMP Off (option)

7. Volume 10

8. CH. Skip Erased

9. CH. Lock Off

10. Timer Off

4-3-3 High Voltage Check

CAUTION: There is no high voltage adjustment on this chassis.
The B+ power supply must be set to +125 volts (Full color bar input
and normal picture level).

1. Connect a digital voltmeter to the second

anode of the picture tube.

2. Turn on the TV. Set the Brightness and

Contrast controls to minimum (zero beam cur­rent).

3. The high voltage should not exceed 27.5KV.

4. Adjust the Brightness and contrast controls to

both extremes. Ensure that the high voltage
does not exceed 27.5KV under any conditions.

4-3-4 FOCUS Adjustment

1. Input a black and white signal.

2. Adjust the tuning control for the clearest pic-

ture.

3. Adjust the FOCUS control for well defined

scanning lines in the center area of the screen.

4-3-5 Cathode Voltage Adjustment

(Screen Adjustment)

1. Connect CRT socket pin GK to an oscilloscope

probe.

2. Input a gray scale pattern. (Use a pattern gen-

erator, PM5518)

3. Use the P mode key (on the remote control)

for the STANDARD picture.

4. Adjust the Screen VR (on the FBT) so that the

voltage on the oscilloscope becomes 120+2.5V
(See Fig. 4-1).

4-3-6 Purity Adjustment

1. Warm up the receiver for at least 20 minutes.

2. Plug in the CRT deflection yoke and tighten
the clamp screw.

3. Plug the convergence yoke into the CRT and
set in as shown in Fig. 4-2.

4. Input a black and white signal.

5. Fully demagnetize the receiver by applying an
external degaussing coil.

6. Turn the CONTRAST and BRIGHTNESS con­trols to maximum.

7. Loosen the clamp screw holding the yoke.
Slide the yoke backward or forward to pro­vide vertical green belt. (Fig. 4-3).

8. Tighten the convergence yoke.

9. Slowly move the deflection yoke forward,
and adjust for the best overall green screen.

10. Temporarily tighten the deflection yoke.

11. Produce blue and red rasters by adjusting the
low-light controls. Check for good purity in
each field.

12. Tighten the deflection yoke.

1. Warm up the TV for at least 30 minutes in the
Aging Mode (OSD White). This mode is dis­played by entering the following sequence:

DISPLAY

2. Input a Toshiba pattern.

(b) Low-Light Adjustment

1. Set SBT to 3.5 ± 0.5 fL in the Factory Service
Mode with using CA100. See Fig. 4-4

2. Adjust RG,BG so that the levels are suitable to
each local area.

4-3-8 Center Convergence Adjustment

1. Warm up the receiver for at least 20 minutes.

2. Adjust the two tabs of the 4 pole magnets to
change the angle between them. Superimpose
the red and blue vertical lines in the center
area of the screen.

3. Adjust the Brightness and Contrast controls
for a well defined picture.

4. Adjust the two-tab pairs of the 4 pole mag­nets, and change the angle between them.
Superimpose the red and the blue vertical
lines in the center area of the screen.

5. Turn the both tabs at the same time, keeping
the angle constant, and superimpose the red
and blue horizontal line in the center of the
screen.

6. Adjust the two-tab pairs of the 6-pole magnets
to superimpose the red and blue line onto the
green. (Changing the angle affects the vertical
lines, and rotating both magnets affects the
horizontal lines.)

7. Repeat adjustments 2~6, if necessary.

8. Since the 4-pole magnets and 6-pole magnets

interact, the dot movement is complex
(Fig. 4-5).
