The problem is finding a really good pinball repair tech that knows what they are doing to help you out. Luckily, I live in an area with a few very knowledgeable people that know how to fix pinball machines, but some are not for hire, or they cost $100 to show up, plus hours and parts. That's ok though as at least I have that as a backup plan. If you are going to own a pinball machine, go into it knowing that you need to know or learn how to troubleshoot the basics as it is probable that things will wear and will fail over time. It's mechanical moving parts being beat to death with a metal ball and lots of electronics. I didn't know too much about it when I started out with pinball, and I'm still learning and not super good at soldering and board type of work. Troubleshooting is a learning process and "part of the hobby". LTG is our best troubleshooting guy that we have "free" access to and he seems to enjoy helping for the love of pinball. Just give him all the details that you can with photos identifying what you are talking bout - or even video links that you can PM him. There is a need for more pinball repair techs out in the world. I've helped out a few people myself. If there is a thread for your local area for something like "What's for sale in <state name here>", make a post there to see if they know of someone local that can help you repair your pin.
All that being said ... yes, NIB pins "should" be working out of the box with very little tweaks needed for small things that happen during shipping. JJP is very good at tracking what is happening that is common that needs corrections and they find solutions to implement. Eric is (or was) at the factory likely checking over the CE changeover on the production line and is looking into these repeat issues. The CE owners and future production pins will likely have much better odds for "the luck of the draw" for no issues or just needing minor tweaks from shipping.
