Long story short. I picked up an old Spy Hunter standup that I was going to part out and determined that it was in too good a condition so I'm restoring it instead.
Progress so far. I've replaced a few components on the stack that were physically damaged when it fell over on the power chassis. Verified all the voltage levels on the power chassis and power supply and they're all good.
When turned on it immediately blows the 2A fuse next to the transformer. The marquee lights come on and the crt powers up to a solid magenta screen. Don't know if the monitor has a bad gun or a bad signal wire, get to that later.
I unplugged all the boards from the harness and added them back one at a time until I determined that the lamp driver board seems to be the culprit. With it unplugged I get a blinking light on the cheap squeak deluxe but no other activity.
I've set the dip switches for system tests but the led on the main stack does nothing at all.
This is my first resto and I understand that SH is one of the more finicky machines to get running.
So the questions..
Should I be getting any other activity with the lamp driver board disconnected or is that one of the system killers?
Anyone have any suggestions what I should do next? I would prefer to fix it myself of course but I'm completely willing to pull all the boards and ship them to someone with experience if that seems like the best course of action.
Thanks!
