Hey guys. I got a problem with my Sega Naomi. It isn’t giving me any picture or sound even when I plugged it in directly to a PC monitor. When I plug it into Jamma via Sega I/O, I get nothing. The dipswitches are set correctly when I plug it into the Jamma (1 up; 2,3,4 down). I know the Jamma is working fine because I plugged it into my SF2WW and it works.
I am using a ATX PSU with adapters to power on the Naomi. I check the voltage for each socket and its giving me the correct or very close to the correct voltage. I replaced the 0.1F supercap and check the continuity for the 8 pin bios chip and there is signal for every one of them.
I have 2 Naomi MoBo that actually does the same thing so it must be something in my end. Any suggestions?
