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.
2. Prior to Adjustment
There are five screen modes, and convergence adjustment is required
for each mode. For adjustment, input the following video signal:
6
Table 1 Input 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 (SH-
D09, etc.) Only PRO-610HD5/510HD5 can use the SH-D09.
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
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 201, 204 and 205)
3. Convergence Adjustment
3.1 Replacement of the EEPROMs inside
the DIGITAL CONV. Assy
IC1410 24LC128P
IC1656 24LC08B (I) P
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
DIGITAL CONV. ASSY
IC1410
Shield Case
IC1656
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
Check whether the data of MODE 1 and MODE 2 are as shown in
Table 2.
Adjustment data:
MAX 1FF

MIN 200
Data can be adjusted with the VOL+ and VOL- keys.

Screen indication
The cross-hatch signal is generated inside the unit, and is auto-
matically displayed in OFFSET CONVER. mode and MANUAL
CONVERGENCE mode. You can turn on and off the cross-hatch
signal with the YELLOW key.
Screen mode:
F : FULL Z : ZOOM C : CINEMA
N : NATURAL H : FULL for HD
The Screen modes change cyclically with each press of the
SCREEN mode key.
Adjustment items can be selected with the numeric keys.
