I could use a little help with my ST. I was getting random ramp shots triggered in gameplay. Tracked it to the second left ramp opto. It was extremely sensitive would trigger by just touching the ramp or opto. I fiddle with it and now it is just stuck on. I need to remove the warp ramp to get to it but having trouble doing so. I have it loose but still don't see how it is suppose to come out. Anyone remove the warp ramp? Does it go out the back or pull it out from the front of the backboard? It would be nice to have some idea of how to do it before taking more things apart.
