Quoted from smiley:When you play them they break. When its just me I play one machine and fix any problems that happen. If I turn them all on and have a bunch of people over, the play count goes way up, so more things break or act up. Law of averages.
Perfectly logical, although my experience in a home use environment suggests an additional factor besides play count. When my pins are played regularly, they hold up reasonably well and you fix things as you go, just as you described. However, when a pin stays powered off for a long time, then gets played, it's not unusual for something to go haywire right out of the gate. I've seen it again and again, usually in the first one or two games after an extended period of inactivity. And, of course, it's never the same thing twice. A capacitor leaked, shorted, and smoked on Indiana Jones, a somewhat hard-to-get-to whirlpool LED failed on WH2O, the LL flipper died on TZ, lower backbox GI went dead on FT (burnt connector), etc. Apparently, pins like to be played
