Hey KLOVers! Please check out this video I made.

Well, simply enough, I brought my Demolition Man down to school, and need to get it back to 100%. I have a few issues that I need help with:

1. Constant Knocking in corner.

2. Pinball getting stuck in one hole, but solenoid is apparently fine.

3. The game keeps trying to eject balls for some reason..

You'll see everything I was talking about in the video.

Some background info:

Game has had all 5 pinballs replaced, and has been somewhat cleaned and had a few rubbers and lights replaced.

Really look forward to some responses, and appreciate any help I can get. Thanks!!!
 
Optos in a game are normally closed and when a ball passes between them they open.

Your problem hints at optos having lost power. Check your voltage test point on the power driver board, or go into switch edge test and see if anything in your game with optos works.

LTG :)
