G'day mate, I've only been here a few days but welcome.
My story is probably much the same as yours, got a pinball for a wedding present and got hooked.
I've got two pins now (time machine & pharaoh project)
 and two upright arcade machines from the 80's ( one jamma one neo geo)

I've had to learn fast how to fix them as I couldn't find anyone to service them where I live.
I've found most things are a simple fix and not to be scared when things go wrong ( most times its just a.wire off)  but it's overwhelming when u first start hey mate

Post some pics of your pin.
