6. ADJUSTMENT

6.1 INTRODUCTION

• IMPORTANT

When replacement of the following assemblies are required during repairs, be sure to replace the EEPROMs with the mounted ones in order to
retain the adjustment data of the unit and to facilitate adjustment after the replacement of the assemblies.

Name of Assy EEPROM Main Contents of Memory

SIGNAL Assy IC2454 [24LC32(I)P] Adjustment data, such as W/B and color data, in FACTORY mode

User data set on the MENU

Notes:

• Even if the EEPROMs are replaced, adjustment may be necessary, depending on the part or assembly to be replaced.
For details, see page 186.

• Even if the EEPROMs are replaced, if the EEPROMs are damaged or if their data have been changed from the adjustment data, the status
before the failure will not be restored. Check the status of the unit after replacement of the EEPROMs, and readjust if necessary.

• To enter FACTORY mode, use the

key(s) on the remote control unit or
main unit. To release FACTORY mode,

use the key(s) of the remote control unit

or the main unit, or turn the power off.
If the unit remains in FACTORY mode
without any operation for 8 minutes, it
will be automatically released.

• In FACTORY mode, data for the picture

and audio qualities are standard, and
the FLESH TONE setting is always off.

• When the unit enters FACTORY mode,

settings such as audio muting, MENU,
and SPLIT (two split-screens) are
released.

• The Convergence data which user

adjusted are within the FACTORY
mode. Clear the convergence data by
releasing the FACTORY mode after it is
further within the MANUAL CONVER
mode or OFFSET CONVER mode.

• When the unit exits FACTORY mode,

the TV/CATV mode becomes AIR
(settings of ANT and CH are those last
stored in memory).

• CONVER. OSD (cross hatch) can be

turned on and off cyclically by using the
YELLOW key only during CONVER
mode (MANUAL, AUTO, OFFSET
adjustments).
(Default: The cross hatch is on only in
CONVER. mode.)

CONVERGENCE ADJUSTMENT

1. Procedures

1. When replacinf the DIGITAL CONV. Assy, replace the EEPROM
of new DIGITAL CONV. Assy with the EEPROM of old
DIGITAL CONV. Assy.

2. Check the initial data for the convergence adjustment.

3.Perform the coarse adjustment for the green to roughly correct
distortion of the green.

4.Fine-adjust the green to eliminate any distortion. The green
becomes the standard for the red and the blue.
If necessary, repeat steps 3 and 4. Green adjustment is completed.

5. Perform the coarse adjustment for the red by roughly converging
the red with the green.

6.Fine-adjust the red until the red is completely converging with
the green.
If necessary, repeat steps 5 and 6. Red adjustment is completed.

7. Perform the coarse adjustment for the blue by roughly converging
the blue with the green.

8. Fine-adjust the blue until the blue is completely converging with
the green.
If necessary, repeat steps 7 and 8. Blue adjustment is completed.

9. Display the green, red, and blue colors at the same time to check
the convergence. Readjust the convergence if necessary.

PRO-720HD, PRO-620HD, PRO-520HD

The data stored in the EEPROMs are as follows:
IC1410
OFFSET CONVER. MODE 1 (DFH, DFV)
OFFSET CONVER. MODE 3
Factory-preset values for convergence
User-adjusted values for convergence (CENTER, MULTI-POINT)

IC1656
OFFSET CONVER. MODE 1 (HDP)
OFFSET CONVER. MODE 2

3.2 Confirmation of convergence data

The convergence coarse adjustment modes change cyclically, as
shown below, with each press of the DOT key in FACTORY mode:

Convergence coarse adjustment

DOT key (pressed once) : OFFSET CONVER. MODE 1

DOT key (pressed twice) : OFFSET CONVER. MODE 2

DOT key (pressed three times) : OFFSET CONVER. MODE 3

Cyclical change

2. Prior to Adjustment

There are five screen modes, and convergence adjustment is required
for each mode. For adjustment, input the following video signal:

Table 1 Input signal

Screen mode Input signal

1. FULL (FULL, 4:3 NORMAL)

2. ZOOM (ZOOM) NTSC (480i) signal
3 CINEMA (CINEMA WIDE)

4. NATURAL (NATURAL WIDE)

5. FULL for HD (HD/DTV) HD/DTV (1080i) signal

NTSC : Stable signal source, such as an SG or an LD/DVD player
HD : Stable signal source, such as an HD SG or a DTV tuner .

When CRTs are replaced or when the deflection yoke is moved,
perform the deflection yoke adjustment, horizontal and vertical size
adjustments, and centering magnet adjustments before the
convergence adjustment. (See Pages 190, 193 and 194)

Make the adjustment for the green in each screen mode, and use
the green as the standard screen for the red and the blue. To
change screen modes, use the SCREEN mode key.

Note: Some coordinates for adjustment points are located outside

the screen. Be sure not to make adjustments on those
points, because adjustment of those coordinates will have
little effect on the screen.

Adjustment Technique

1st step

Adjust so that the vertical and horizontal lines forming a cross at
the center of the screen become straight. Check also the screen
size and the linearity of the horizontal and vertical lines.

H: ∗∗∗ Adjustment data in the horizontal direction
V: ∗∗∗ Adjustment data in the vertical direction

( ∗∗∗= hexadecimal number)

MIN 200

For adjustment, move the Line to the desired direction with the
cursor keys.

To move the Horizontal Line upward, press the " " key.
(The value decreases.)
To move the Horizontal Line downward, press the " " key.
(The value increases.)
To move the Vertical Line to the left, press the " " key.
(The value decreases.)
To move the Vertical Line to the right, press the " " key.
(The value increases.)

• To select one color, use the SEARCH key for the red, SELECT
key for the green, FREEZE key for the blue. Pressing this key
toggles color muting on or off.

• To mute all the colors, press the DISPLAY key. To release
muting, press the SEARCH, SELECT, or FREEZE key.

• To erase the cross hatch, press the YELLOW key.
Pressing this key toggles between display of the cross hatch
screen and the input screen.

• To change the brightness of the input screen, use the VOL+ or
VOL- key. The brightness increases with the VOL+ key
(CONTRAST +10) and decreases with the VOL- key
(CONTRAST -40). (The brightness can be changed only in Fine­adjustment mode. The brightness of the cross hatch screen
cannot be changed.)

• See "3.3 Coarse adjustment of the green."
Adjust GH STATIC, SKEW and SIZE, and GV STATIC,
SKEW, PIN and SIZE to correct the screen location, tilt, screen
information volume, and peripheral pin distortion.

• See "3.4 Fine-adjustment of the green."
Fine-adjust the linearity of the vertical and horizontal lines
forming a cross at the center of the screen.

Note: In principle, only the selected point is changed in

MANUAL CONVER. mode. However, as the adjusted
data (amount of adjustment) increase, peripheral points
may be affected. So be sure not to greatly change the
adjustment data of one point, but change peripheral points
at the same time. See the examples below.

If an adjustment point is
greatly moved to the right,

Peripheral points may
be affected.

2nd step

Adjust so that the vertical lines become straight, taking care to
preserve proper screen information volume and the linearity.
Adjust the right half of the screen first, then the left half.
(See 3.4.)

4th step

Repeat 2nd and 3rd steps to take total balance. Then the adjust­ment for the green is completed.
To return from the fine adjustment mode to the coarse adjustment
mode, press the MENU key once, then the DOT key.

Note: When the MENU key is pressed to quit MANUAL

CONVERGENCE mode, the display will be unstable for
several seconds. This is because the adjustment data are
being written to the EEPROMs, and is not a malfunction.
Do not perform any operation (power on/off, or pressing
keys on the remote control unit or on the main unit, etc.)
during this period, because doing so may affect your
adjustment data.

Right half : Adjust from the edge toward the center.
Left half : Adjust from the center toward the edge.

3rd step

Adjust so that the horizontal lines become straight. Adjust the
upper half of the screen first, then the lower half. (See 3.4.)

3.6 Fine-adjustment of the Red

To fine-adjust the red, press the SET/ENTER key to enter
MANUAL CONVERGENCE mode. Repeat the coarse
adjustment described in "3.5 Coarse Adjustment of the Red" if
necessary. Make adjustment for each SCREEN mode, and
eliminate distortion to converge with the green.

3.6.1

Press the SET/ENTER key to enter MANUAL CONVERGENCE
mode, and make adjustment in the same manner as with the green.
First, adjust the vertical and horizontal the red lines at the center
of the screen so that they converge with the green center lines.

3.6.2

Adjust the red vertical lines so that they converge with the green
vertical lines. Proceed to adjustment of the right half of the
screen, then the left half. Adjustment should be done from the
part where convergence is greatly dislocated.

3.6.3

Adjust the red horizontal lines so that they converge with the
green horizontal lines. Proceed to adjustment of the upper half of
the screen, then the lower half. Adjustment should be done from
the part where convergence is greatly dislocated.

3.6.4

Repeat the adjustments described in 3.6.2 and 3.6.3 so that all the
red vertical and horizontal lines converge with the green lines.
(Completion of one screen mode)

200

PRO-720HD, PRO-620HD, PRO-520HD

3.6.5

Repeat procedures 3.6.2 through 3.6.4 for the other screen modes.
(Completion of the red adjustment)

3.7 Coarse Adjustment and Fine Adjust­ ment of the Blue

Make coarse and fine-adjustments of the blue in the same manner
as with the red, described in 3.5 and 3.6.

3.8 Confirmation of Adjustment

After the green, red, and blue adjustments are finished, check
convergence errors with the patterns for all three colors on the
monitor.
Check the patterns in all SCREEN modes, and if any error in
convergence is recognized, readjust convergence in MANUAL
CONVER. mode.

Note: Be sure NOT to change the green pattern during readjustment.

IMPORTANT!

(1) When all the adjustments are completed, or when adjustment

should be temporarily interrupted, adjustment data must be
written to the EEPROM, in the following manner:

When all the adjustments are completed, or to interrupt
adjustment, press the MENU key to quit Convergence
Adjustment mode. The display will be unstable for several
seconds, but this is because the data are being written to the
EEPROM. Wait without doing anything until the display
becomes stable, which means writing of data to the EEPROM is
finished.
If the power of the TV is turned off (standby) during Convergence
Adjustment mode (coarse and fine-adjustments), turn on the TV,
enter FACTORY mode, and enter Convergence Adjustment
mode by pressing the SET/ENTER key. Then press the MENU
key. The data will be written to the EEPROM as described above.

(2) Do NOT turn off the main power during or after convergence

adjustment.
If you do so, the adjusted data may be lost. If the data are lost,
you must make all the adjustments again.

(3) When the CENTER POINT (test cross) or MULTI-POINT (user

convergence) adjustments have been made by a user, and if the
unit enters FACTORY Convergence Adjustment mode (with the
DOT and SET/ENTER keys), the user's adjustment data will be
all cleared and returned to the factory-preset values.
Be sure NOT to enter this Convergence Adjustment mode except
when a repair related to convergence or a repair that requires
convergence adjustment later, is needed.
If you inadvertently enter Convergence Adjustment mode,
readjust the convergence.

Do NOT change other data.
Other data are adjusted in factory
shipment by Fix data of the following
table . (refer to page 204.)

• First, perform "(1) STD OFFSET", then perform adjustments (2), (3) and (4) so that the same picture
quality (color temperature) as achieved in (1) is obtained.

• In adjustment (5), make the whole picture more reddish than in (1), and in adjustment (6), make it more reddish.

• When readjusting, once "(1) STD OFFSET" is adjusted, the data for other input signals (component, etc.) revert to the factory-preset

values, in principle.

• After the adjustment of STD OFFSET is completed, check other picture quality modes by switching color temperatures and signals.
It is OK if picture quality does not deviate greatly when input signal is changed (composite, component 15K, etc.).
Furthermore, it is OK if color temperature changes when color remperarure is changed.
With this model, five color temperature switching modes are provided. In FILM and B&W modes, a white part appears to be reddish in
general because of their color temperature settings.
