Ceronix 1492 Troubleshooting Help

[Chris-socal]

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.

No problem Chris. You're very active on this board so i can only imagine trying to keep all the conversations strait!

Update on the machin: She's up and running!!!

Turns out there is a repair shop only 10 miles from me. The tech hooked up my board and 1 or more of the 7 chips in the set were bad. He did a chip swap, cleared the board and its working great!

Thanks for all the help on this issue Chris!

Cheers,
Chris

Congratulations! Now that’s a great ending, how amazing to have a tech close by. So glad we could help.

Awesome! how does the CRT look? I'm very impressed with how far you had gotten it, and Chris is the man!

The CRT looks great for it's age! I'll try and post a better pic than this. At the time i took this picture, the red and black chips were swapped on the main board resulting in the color errors you see. Chris was a huge help in guiding me through the process to resolve the issues with the monitor.

The process of bringing something back to life that was thought to be junk is very satisfying

Glad to help. Those 1492’s are well worth keeping around, they usually have a lot of screen burn but you can’t see it when the game is in play.
You also cannot discount the technician who did the work! They are scary to work on the first time.

Awesome! Most people would have knocked the neck and trashed it. Glad you put the work in!
