A microelectronic short circuit detection module is disclosed that locates and distinguishes among different types of short circuits in touch screen panels. Individual short circuit detection circuits are coupled to force and sense lines throughout a wire matrix within the touch screen. If the line is shorted to a neighboring line or any other line carrying an opposite logic state, its logic state will be corrupted by the short and will be held at a value opposite that of the intended input signal. Comparing the input and the output therefore provides an indicator of a short circuit to another force or sense line in the wire matrix. A pair of pull up/down stages is engaged to detect whether the short is coupled to power or ground. A threshold resistor can be varied to adjust detection sensitivity. By conducting a serial test, matrix coordinates of the short circuit can be identified.
