To understand how the Monitor works, it is best to know what each circuit does and how each circuit relates to the other circuits. The Block Diagram is presented in a simplified view and a comprehensive view to accomplish the goal of understanding the whole unit. Once the general picture is clear, the complexity of each circuit will be easier to understand.
The Circuit Description is also written in two views, a simplified view and a detailed view to help give the reader a clear understanding of what each component does. This understanding is most helpful for the more complex problems or multiple problems that sometimes occur.
The power supply trouble shooting section describes methods used to power up various monitor circuits, when there is a fault in the monitor, which disables the power supply.
The appendix includes; filament voltage test, convergence procedure, replacement parts purchase order form, degaussing coil attachment specification, high pot test, wire routing drawing, production assembly drawings (PADs), C, I, J,
&K film resistor arrays and a parts list addendum. The parts list addendum is used to add new information describing part changes. Tables, suitable for pasting on these pages, will be published as new variations of the XX93 monitors are produced.
