I'm working on tuning up my pinbot, getting all the minor gremlins out and putting in LEDs. Couple things I was wanting some help with.

-The right flipper switch works, though the lane change function doesn't work like it should. Sometimes it'll work, but not consistently. Also noticed that it's just as iffy when using it to enter initials for a high score. Cleaned the contact points, though noted they seems pretty worn. Wondering if it's sometime that can be fixed or if I should just replace it. Also, is the lane change supposed to go from left to right for both switches?

-I've been working on testing LEDs for the inserts. For some reason, the yellow-blue-orange-green-red light matrix in the middle won't work when I tried a couple 555 LEDs. Any ideas on the reason and/or how to fix it?
