Abstract : A pattern generating circuit is disclosed for providing a fixed test pattern to be broadcast on a video display system such that an individual may test or repair the aforementioned video display system. The pattern generating circuit provides a horizontal sync signal, a vertical sync signal, and first and second video component signals which are then supplied to the video display system so as to activate the same. This, in turn, allows the video display system, upon receiving the video signal, to broadcast on its display screen the fixed test pattern.
