My F14 started resetting. I have read bad diodes can cause this. I replaced the diodes on one flipper coil. The others look fine. It resets when I first turn on the game for about a minute or two...especially when double tapping the flippers. Then it stops so I am thinking it isn't a diode issue but possibly a power board issue until the game heats up? Bridge Rectifier? Sometimes the issue goes away if I power on the machine and power off. Any suggestions before I shotgun all the diodes?
