Hi folks. I have a couple of basic level questions on a voltage problem I am having with Asteroids.
First, I have been doing some reading of various threads on here and they have been a big help...I got to the point of where I am now just by learning from others. Thank you community.
This Asteroids game was in my storage for like 15 years and I was finally able to retrieve it and bring it home....across the country.
Game doesnt play. No surprise. So I started checking connectors, etc. I used some electrical spray on the molex connectors and got the machine to hum through the speaker now..where it would not before I sprayed it...so progress there....
Questions:
1. There is an LED light on the Asteroids PCB board. It does NOT light up except when you either power on the game or power off.
2. After watching videos, I tested the AR board. I found I am getting 12vDC just great but only getting 1.5vDC on the +5v side. So I am not getting 5v to the game, presumably...and probably why the LED light is not on....and why the speaker hums...
Does this sound like a cap kit for the AR board?
3. I am getting AC for the coin door lights. The monitor neck has glow and the LED light on the monitor chassis is on full time. (unlike the game pcb)
4. The marquee light does not work but on that there is a loose wire going to the ballast to fix or I have a bad ballast...parts are enroute. (tried swapping tube and starter already)
5. All fuses have continuity and are good...I have not cleaned the area just yet but I did shop-vac the dust out from inside...tons of old mice bedding inside.
6. And last, I did spray the edge connectors for the game PCB...but I think my issue is voltage at this moment.
So analysis, anyone? The AR board is really suspicious to me right now.
Thank you!
