ABSTRACT:
A display device testing circuit includes a false video signal generator for producing a false video signal from a blanking pulse of the display device in a state where no video signal is connected to an input terminal of the display device, so that such false video signal is supplied to the video amplifier. A false clamp pulse generating circuit produces a false clamp pulse from the blanking pulse and supplies the false clamp pulse to a pedestal clamper in the video amplifier, thereby realizing a simplified test of the video amplifier at low cost.
