6. GENERAL THEORY OF OPERATION
6-1 BLOCK DIAGRAM
Above is the block diagram of the monitor as a whole. Each major section is
presented in a block. The individual circuit that makes up the section is covered later and is
not shown here. This simple block diagram will allow you a fundamental understanding of
the complete monitor. This will help when covering the sections individually. The process
from video signal to video display starts with the video signal generated from the source.
The signal is composed of information that is fed into various sections of the monitor
the following diagrams are based on 17"/19” VGA auto bias monitor and are included for
reference only. Actual circuit may be different. Please see update schematic and parts list
enclosed.
