Green raster adjustment
Caution
1. The following adjustment have to be carried out one with
PAL signal (50Hz) and with NTSC signal (60Hz).
2. Raster adjustment need to set the P-CONVERGENCE
to Zero Correction some time.
Preparation

Helpful Hint
All positions which have been adjusted are recorded within
P-2 for NTSC data and P-3 for PAL data of the memory.
This data can be copied to P-4 memory area, allowing you
to perform the adjustment of P-2 (NTSC) and P-3 (PAL).
To perform these adjustments, push the SEACH button on
P-2 for NTSC data and P-3 for PAL data of the memory.
This data can be copied to P-4 memory area, allowing you
to perform the adjustment of P-2 (NTSC) and P-3 (PAL).
To perform these adjustments, push the SEACH button on
the remote control, and manipulate the position [
] and
[
] button and the “N” button as instructed by the On
Screen Display in P CONVERGENCE adjustment.
All of the Convergence Control Charts have been listed for
the remote control buttons after the Convergence Adjust-
ment Procedure Please refer to these.
