I recently acquired a Bomber Powerful Pachislo. Everything is in perfect working order with the exception of when the machine is first powered on. Regardless of if the machine is turned on using the power switch inside or just plugged into the wall, it immediately pops an "E-8" error code on the screen and requires a full reset. I have tried several things from turning it off and counting to 5 then powering back on to hooking it to a surge protector and shutting it down that way. All result in the "E-8" error. My assumption is some sort of boot up issue with the board. Any thoughts on a quick fix or an option for replacement parts?
