I've got a Stargate that I've converted back from a bad conversion of Jail Break. Today is the first time I've tried to get it to run and I don't get anything on power-up except speaker hum for a couple of seconds and one coin door light that comes on.
It has good voltage at the power supply and coming in to the board. I also get decent voltage at the ram, I think. It's 4.85 and 11.97.
I've done all of the basics like reseating chips, cleaning contacts points for cable, etc.
The monitor is also known good. I rebuilt it recently and used it to test a machine a few days ago. There is glow at the neck on it.
I don't have any spare ram on hand, but on the other Williams machines I've dealt with I would at least get some output to the screen or sound to let me know that it has something going on with it. Even with bad ram.
Any suggestions?
Thanks,
