I checked the filters and there was one with a short. But it was not the filter itself. On the solder side of the PCB was a small blob of tin that shorted the filter. I removed it and the GS is working perfectly now. This is a photo of the pcb: http://www.richardlagendijk.nl/foto/cip/xxl_info_reparatie_gs64_01.jpg I don't think this Games System 64 ever worked perfectly, I do not know where it came from. I was asked by the Dutch Commodore user group to repair it. Thank you all for the help!
