ABSTRACT:
A self-testing video display device and method of use. A video display test program is stored in a video processing unit inside a video display device. The test program includes a plurality of video test patterns and is accessible by entering a “secret” keycode combination on a keypad of the video display device. The self-testing video display device allows a service center operator to evaluate a malfunctioned video display device at the user's location through telephone or internet. An end user may also use the video display test process to set up, evaluate, and calibrate the self-testing video display device at the user's location.
