7.  Write data into memory.

•  Input an all white 480I (15.734 KHz) signal into the VIDEO 1 input 

terminal to perform the White Balance (highlight, cut-off) adjustments.  

The parameters to adjust are in the CXA2170P in Service Mode.

•  Input an all white (30 IRE) signal to the specified input.
•  Adjust the white balance using the specified registers.

1.  Face the picture tube in an east-west direction. (For best condition.)
2.  Complete V-PIN and V-CEN adjustments first (A2170-D1 06 V-PIN, 

A2170-D1 05 V-CEN).

3.  Input a monoscope and crosshatch signal.  Adjust the picture 

distortion with the following service parameters to balance the best 

condition for these two signals.

 

NOTE:  Make sure that the picture size is within specs.  Vertical size 

is  11.8 ± 0.1 sq. and horizontal size is 15.8 ± 0.1 sq.

4.  Write data into memory before changing modes.

Item 0.  VPOS (V-POSITION)

Item 1.  VSIZ (V-SIZE)

Item 3.  VLIN (V-LINE)

Item 4.  VSCO (VS-COR)

Item 9.  HTPZ (H-TRAPEZOID)

Item 1.  HPOS (H-POSITION)

Item 2.  HSIZ (H-SIZE)

Item 15. VANG (AFC-ANGLE)

Item 16. LANG (L-ANGLE)

Item 17. VBOW (AFC-BOW)

Item 18. LBOW (L-BOW)

1.  Input a 1080i cross-hatch signal and an HD monoscope signal that 

contains overscan markers.

2.  Adjust the raster position per Section 2-8., only if this procedure was 

not performed for full mode.

3.  Adjust the geometry similar to Full DRC mode.  Vertical size is 11.7 

± 0.1 sq. and horizontal size is 15.6 ± 0.1 sq., if monoscope signal is 

available.  Otherwise, set the Vertical size to 91.0 ± 0.6% scan and 

Horizontal size as 91.0 ± 0.6% scan.

4.  Use the following register to adjust the horizontal parameter:

A2150-D2

01

HPOS

 

NOTE:  If necessary, touch up the geometry using the data register  

 listed above for Full mode. Check NTSC full mode for side  

 

effect and balance.

5.  Write the data into memory before changing modes.

1.  Input a monoscope and crosshatch signal.
2.  Check vertical compressed mode.
3.  Adjust VPIN if needed.

TWIN mode and FAVORITE mode use the FULL mode adjustment data. 

The key point for TWIN mode adjustment is the blue border appearance. 

The left border on the left picture should not be visible when the left 

picture is selected. Similarly, the right border on the right picture should 

not be visible when the right picture is selected. Balance the HPOS or 

HSIZ data for FULL and TWIN mode.

For INDEX mode, however, no clipping of the picture edge should be 

visible for the small sampled pictures on the right side. Adjust HSIZ/

HPOS to balance FULL and INDEX mode for this. Avoid displaying the 

edge of the raster in FULL or FAVORITE mode.
