    • A self-diagnostic arrangement for a video display apparatus and method effectuating the same is disclosed. The apparatus according to the present invention includes a cable connector, amplifiers and a cathode ray tube and comprises a microprocessor storing information on a display status, for selectively switching signals to generate horizontal and vertical sync signals for displaying a variety of self-diagnostic displays, an on screen display IC for supplying a blanking signal and a video signal correspondingly responsive to information supplied from the microprocessor and a H/V deflection circuit for supplying on screen display video. signals to the CRT. There is also provided a method of self-diagnosis, which comprises the steps of generating internal horizontal and vertical sync.signals of predetermined frequency levels and displaying self-diagnostic screens representing video component colors and a display status.
