Naomi powering on, but no picture EDIT: fixed

[MostVerticalPrimate]

Just bought a Sega Naomi setup with a Capcom IO for my Supergun. Plugged in all of the needed components and plugged the harness into the IO. The Naomi turns on and sounds like a jet engine, which means it's getting power, but no signal comes in. In some cases, it attempts to make a signal, but the TV acts as if there is nothing. I've flicked between the dip switch settings for 15K and 31K and used my VGA monitor but no results. I have a multi-region bios, but currently no cartridge (Akatsuki Blitzkampf, but it's on loan). Am I doing something wrong or is it messed up?

Your TV may not be able to display the output signal. Try a PC monitor to check.

plugged it into a spare monitor I have, using VGA. Still yielded no signal.

In the pictures I can't see where you have connected a VGA cable directly to the Naomi.
Make sure the Naomi is directly connected to the VGA monitor and set the dip to 31khz.

Why do I see no VGA cable whatsoever in this shot?

How did you expect this to produce an image, no cable is connecting Naomi's video to the Capcom IO.
Again I see no VGA cable period, not connecting the Naomi directly to a VGA monitor and not connecting the Naomi to the Capcom IO.
So yea... No video bro, think you are doing it wrong.

You are aware Naomi ONLY sends a video signal out of that one VGA port on system right?
No matter what position you have the dip set, video only flows from that port.

I know that now. Had no idea the VGA was mandatory. But it works.
