Ok I fixed my display issues be reusing my old 21 pin connectors.  I thought I would never get the old connectors out since I had cut them all off so there was nothing to grab onto once you stick the extraction tool in.  I ended up cutting them off since I had already broken 2 extraction tools and only managed to get one or two out.

Problem was now I needed to reuse the connector since they don't make 21 pin ones anymore.  But I found a much easier way to get then out.  I used a small flat head screw driver and instead of taking the pin back out the way it was first inserted, I leveraged it forward and right thru.  Worked a treat I had 21 connectors out in less than 5 mins. 

After repinning the 21 connectors my display problems were gone.

The other stuff is still an issue.  On boot up I get the following messages:

"stuck switch" - although I cannot see any switches touching except for the coin door slam switch which is closed and the bob tilt switch which is closed (as they should be).

I also get the following rolling message: "Chute 1, Chute 2, Credit, Tilt, Slam"

I also get "Check Coils Danger Locked On" (but can't find which coil, not sure how to test for this)?

Any suggestions, are all the problems inter-related?
