I am very happy to hear that you were able to begin talking to a possible source that can assist. That is great. Last thing you want is to get so frustrated that you just move on to something else as these machines are quite fun when they are working. I say this as I routinely have my local tech come out fir misc problems that just occur. Machine has not been moved, cleaned or even played and yet when I go to turn it on that next time, something is not right and the machine does not work. The old adage is true. If it’s not broken it’s not pinball.
While I completely appreciate all those that have been very encouraging and offering of great information, for some, like myself, I would just prefer to have someone with the right skill set come over and handle the issue. Pinball stays fun for me this way. I loathe having a machine that is not working properly even though mine get precious little use. They have to be right.
Do what you do well and let others do what they do well. Just because you may not have an affinity or desire to learn every aspect of pinball maintenance does not mean anything other than you don’t want to do it all. For those that can I admire you. You can do something I cannot or will not devote the time for do to other commitments or plans. I can do some basic stuff and that is where I knowing it is more involved call “the guy”!! I take pride in what I can do and admire what others can do. Put them both together and my machines are always up to snuff!!
