1.  Face the picture tube in an east-west direction. (For best condition.)

2.  Complete V-PIN and V-CEN adjustments fi rst (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.

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

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.
