Sorry my last reply for the 0.16 Volts is wrong, i didnt read it correctly.... 0.16 Volts sounds about rite


You should be getting around the voltage you measured 0.16..anywhere around there will be ok..

with just the vga lead connected to the PC you should be reading the H sync voltage at around the 0.1, 0.2, 0.3 volts. Can you double check that? black lead on the PC case or any ground,  red lead on the vga H sync pin with the VGA lead only connected to the PC, no amp, no chassis, you shouldnt be getting 0 Volts..
