I speant the better part of 8 hours removing chips, cleaning and replacing legs today. It was a lot of fun and a learning experience.
When I power it up, the screen is blank but powers on, the speaker makes clicking noises or no noises.
I get 5 volts to the CPU and video PCB. It has the original, linear power supply.
Other than that, I am not sure where to go. I've tried using the troubleshooting steps from here, but they don't say much in the way of a dead system: http://www.arcadeshop.com/galaga/galaga.htm
I have an o-scope and a multimeter at my disposal. This is also my first restore attempt and I'm pretty excited.
