Hi Rein, Regarding your question about Pin 2 of the CCD - the signal on this pin is a series of -7V pulses which occur each horizontal line, and a +15V pulse which occurs each video field. It is this +15V pulse that the diode is meant to shunt to 0V. Are you sure the diode is connected the right way round? If it has a band around one end of it, the band should be facing away from Pin 2. Good luck, Jon.
