UPDATED! Control panel not working on Naomi Uni cab

Well its hard to explain it better than what Andy said :

On the power connector (on the naomi motherboard) :

black probe on a white wire + red probe on a yellow wire = checking 5V

black probe on a white wire + red probe on a brown wire = checking 3.3v

Sorry, I'm just getting frustrated...

Check youtube or google how to use a multimeter, it's not an arcade specific skill - but comes in handy when dealing with cabs.

Thanks for your reply dude.

It's the first part of your reply that I wasn't able to interpret from Andy's reply. I didn't know which wires to test.

So, it's the power connector.

Thanks,

Steve

UPDATE: 4/11

Okay, so I tested the voltage on both the 5V and 3.3V going into the mobo.

I got 5.18v and 3.31v under full load (game powered on.)

I adjusted the pots so the new readings are 5.2v and 3.5v while the game is running.

I double checked all of the connections to the I/O board, and to the CP, as well as to the mobo, and everything is connected.

I get no response from my Control Panel at all now.

Nothing from the buttons or joystick.

Can anyone think of something I might be missing, or what the problem could be? I'm really stumped here.

Thank you,

Steve

Also, while I'm at it, can anyone help to identify the numbered things in these pics?

I'm not sure what they all do, and don't want to go messing with them (I'm sure some have to do with R/G/B for the monitor, horizontal/vertical, or whatever.)

1.

2.

3.

4.

5.

6.

7.

8.

9.

Does anyone know what these are for? I've numbered the pins on the mobo 1 & 4, and the connectors 2 & 3.

I don't have any clue what they're for.

3.

4.

Thanks as always guys.

The 8 'controls' are for the CRT. The other connectors are serial, Midi and Maple connections. The serial is to connect things like card readers. The Midi is connected to things that need constant variable digital control such as force feedback. The Maple connectors are peripheral connections for things like what you might connect to a Dreamcast such as keyboards, game controllers, VMU's, etc. for games that support them.

In short, none of these can be used instead of the I/O. In fact, I think you should remove them to emliminate any sort of possible connection problems. :smt045

Thanks Josh.

Any idea about the CP problem I'm having?

This may sound like an odd question, but do you have a counter connected to your I/O? When I first hooked up my Naomi setup, I had no controls whatsoever. I connected a counter and everything worked fine.

Honestly, I have no idea. Where can I check this?

It's just weird for them to work, and now they don't.

Voltage checks out, connections are secure, and the I/O seems to work.

Still hoping someone can help me with my problem here.
