I've got an annoying problem with my recently acquired High Speed. When I got it it would display the error knocks on start-up and report the "Check Switch 38 - RT Flipper EOS" and the right upper flipper would occasionally work. I replaced both EOS switches on the right side, upper and lower, adjusted them, and also adjusted both flipper button switches. The flippers work perfectly every time now but the switch tests still report the same error. Also of interest, when imputing high scores the right flipper is not recognized, you have to scroll backwards with the left flipper. It's almost like the flipper isn't there even though it's working now. I'm pretty new at this so any help is really appreciated.
