I recently bought 2 cabinets, with some new buttons, joysticks, etc. One of the cabinets is gutted, and the person was going to make a MAME machine, and I plan on the same, but the other he said should work with a new power supply.

It's an original Donkey Kong that was converted to Arkanoid. Now I know little of electronics, but do work with computers, so not everything is foreign.

I am trying to connect everything together, but had no idea on the monitor connections. I have some pictures below of the monitor. I'll try to find the model, etc if it isn't apparent from the pictures, but it is vertical, and could be original to the Donkey Kong cab.

This also has the pictures with descriptions of what I think they are

Any help or direction within these forums would be greatly appreciated!

Well I got my multimeter out and looks like the board is being supplied the 12 for the sound and all of the 5 are live. I traced the sound all the way to the speaker and it's getting power, but no sound. Is this a valid first step on determining if the Arkanoid board is working? The monitor has some burn in, but it does light up and shows red/green lines. I think I have the monitor hooked to the PCB as well, so not sure if that's the game or not. I was trying sound first, as that seemed easiest.

I've searched through the forums and stickies, wiki, etc. but can't think of what to try next, or if what I'm doing is valid with just the basic power running to the board and speakers. Please let me know if I'm making any sense.

Thank you.

Looks like I'm missing a monitor connection. I have the grounds, video ground and video red, green, blue, but the video sync was not hooked up. Now I have to figure out how they're connected to the inverter, and make sure they're all right. I'd have to assume so, but this is my first time wiring anything, so don't want to assume anything.

Edit: Added the invertor ACSII, and verified it is getting power and is connected to the Non-Nintendo side. All the wires were off, but are correct now, but the display is still showing lines (picture attached).

Please let me know if anyone has seen this and what it might mean.
