Have had this happen pre power rectifier replacement. Installed a homepin rectifier but the problem still occurs. During attract mode and being left idle for some time (don't know how long) the score displays and pf go out and only a few lights on the backglass are locked on. You cannot start a game. The only fix is turn off and on. The problem only seems to occur when there is an extreme load on my house's power. If the game is on with only a few games, the problem doesn't seem to occur. Last night I had the photographer around for the sale of my house so all games on, all 120+ halogen downlights on and whatever else. Afetr a bout 5 mins SI died.
Any ideas? Is there some kind of power fluctuation thingy going on here and what can protect the from locking up? thanks. oh I have 3 phase power installed in my house.
