rchjr - I do not recommend fixing a Pro 96 as its Hardware Limited to only onboard programming and its likely a repair might cost more than a WS 1080/1088 scanner NEW.
the Pro 96 is also no longer Supported and you cant add a computer. the Pro-688/ WS 1088 is a better scanner, it has a SD card with the Entire USA/Canada database on it. and you can update with a Windows computer. Programing by PC is much easier and faster than by hand, Bonus, you also get FREE Lifetime updates for the Database and more.
I'm not sure where in AZ you can repair a Scanner, perhaps try HRO ? Ham Radio Outlet.
