Resolution/Work Around:  The error 4 is an ADC error (Analog to Digital Converter).  This is caused when the ADC is not converting or producing a usable signal to the controller.  The ADC chip has gone bad.  Replacement of the analog board or the controller, dependant on the model being serviced, is recommended.
