DP-4X RGB PROCESSOR CIRCUIT EXPLANATION
(Continued from page 04-07)
IY04 RGB Processor Outputs;
The RGB Processor is responsible for final preparation of the signal before it arrives at the CRTs for display.
Brightness, Contrast, Pedestal Level compensation (DC Restoration), Time Compression, Black Peak Expansion,
Room Light variance compensation, Color Saturation, Tint adjustments, Sports, Movie and News Modes are all a
part of this Chips responsibilities.
After the signal has been processed by the RGB processor chip, it outputs the RGB signals on the following pins
to the CRT PWB via the PSC connector.
•
R (Red Output) via pin 12. Through QY52 to pin 5 of the PSC connector.
•
G (Green Output) via pin 13. Through QY54 to pin 7 of the PSC connector.
•
B (Blue Output) via pin 14. Through QY56 to pin 9 of the PSC connector.
