Reviving a System 1 takes method and ....money.

Most of the electronics on System 1 are either dead or partially damaged. Spare parts are impossible to find (ok, next to impossible). As ForceFlow indicated, there are a few vendors who have done a fantastic job at replicating (and improving) the System 1 electronics.

Personally, I like the French Manufacturer FLIPPP ( https://www.flippp.fr/boards.php?lg=en ). His boards are just fantastic and will get your machine playing in no time.

But first, you must go thoroughly through the Power Supply board located at the bottom of the cabinet. You must verify each transformer and especially the small one.

Here is a link about the complete restoration of a Buck Rogers which uses identical electronics as the GENIE:

There is plenty of information on this forum and on the WEB on how to repair and fix System 1 pinball machines. Take your time and read.
