Hey pinsiders. I purchased my first machine, RCT a week ago and everything was working great the first few days. I know almost nothing about machine maintenance but I was having problems where the center ramp would not always register so I took the glass off and I was able to fix the problem by simply restraitening the metal bar by the switch. The ball also rarely get stuck under the playfield where the info booth is. I lifted the playfield and propped it up but couldn't see anything that looked wrong so I put the playfield back but when I was sliding it back into place it made a not-so-good noise, but I didn't think much of it cause it often makes harsh bangs and noises when moving it anyway. I left on vacation the other day and when my brother try's to play he says it gets stuck while booting on "display version a.700" and the lights just slowly blinking. Can anybody help me? Thanks!
