Namco Noir Red - Powers on but the marquee light and the jvs controls are not getting enough power

[GamerDad85]

Hello everyone, I have this Noir Red that was working fine before but suddenly it is not sending the power correctly to the Marquee light and the JVS controls (output usb type b cable).

I have checked the power distribution small board NR38-6490 and there was a bad capacitor that was replaced but maybe the Relay is the problem? I hear like a clicking sound when the machine powers on, everything else works fine like sound and picture so I am not sure.

Anyone have any suggestions? Thanks in advance.

You should measure what the PSUs are outputting.

I might have to get a multimeter for that. Where do you check the power output? On the PSU itself or on the other boards?

Any cheap $20 digital multimeter will do.

You first check the outputs on the PSUs, and then the break out board (the one with the relay).

What does the unplugged connector do? I see 2 unplugged on mine but can't find out anything about them.

There are some unplugged connectors coming out of the harness from mine as well. Isn’t one of them powering the Banapassport card reader? No idea about the other one, I was even thinking that it might be to power on the system 246/256. For the unplugged ones from the picture I have no idea.

Yeah that's the one I meant the yellow/black wires one.

@nem will know.

Isn't that for the 24V PSU on the right? If you have replaced the monitor there's no need for it.

There is 2 one for the monitor & another unknown one.

So much neater on the Grigio 1 PSU does everything the same unit as the P Ras has progress I guess.
