Ceronix 1492 Troubleshooting Help

I can't remember, did you say you checked continuity on the RGB wires from connector at the monitor to the board?
Color issues are common on those game boards but if Alan serviced it he likely replaced the 3 color pots with resistors. You might want to check around the board in the upper section to the side of the big transformer (middle top of board). It's possible there is a solder gap or broken trace. That transformer is heavy and sometimes the boards or traces break in shipping.

I did check the continuity from the monitor down to where the cable plugs in to the board under the logic board. Continuity was good between those points. Ill check between that plug and where the board drops in later.

I'll go through the board closely and see if i see anything. It's pretty clean for the most part besides some brown residue above the transformer. I slightly lifted each removable chip and pressed them down thinking one of the pins was corroded but no change

It's puzzling    but then again...i do enjoy a good puzzle!

I'm so sorry, I'm getting my Ceronix conversations mixed, this is a PE, not a Fortune. You do need to verify the wires from monitor to back board but also trace them on the back board from source to pin out to the board. Or at least look for something that looks problematic (broken traces). Is this a PE or a PE Plus, I thought PE had black cable connectors that plugged directly into the board. This has back-board connectors.

One thought, I haven't looked at a PE board closely but any chance it has a transistor or color pot for each color?  I can't see the picture clear enough. If there are 3 transistors next to each other on the board that's a good place to start. Same deal, you don't want any shorts. In your situation one of them would test like a diode (good), two would be different (shorted or open).

EDIT: Looks like you have a PE+ Super Board. Take a look in the NLG File system, there is a manual that has a circuit diagram. I highly suspect there is a color controller section on the board. If you can't find a blatantly obvious problem you might need to send the board into K-Lar.
