Hi guys, my dad has a data east lw3 machine that he acquired and it played great for a long time. Then one fateful day it turned on and started but the solenoid would not kick the ball over for launch, we removed the glass and dropped a ball in and the machine played and scored but the kickouts and drop target resets were a no go. So presumably the problem would be something that is in line with all the solenoids. What do you all think is the problem, and how do i test to know for sure?

Ok I got over to my dads this weekend and setup LW4 and took a look at the power supply as per Russ's suggestion, I seem to be getting voltage across each fuse on that board, likewise all the fuses there look good. I played around with the game to see what works and what does not, it seems to be all the outhole solenoids only, the bumpers and flippes work fine. The launcher also works fine on startup (to eject any ball left it the launch position when the game was turned off) but the ball will not launch when a game has started, my guess is that the machine gets no signal that a ball has been kicked over to the launcher to launch. So the game is playable with glass off, and the outholes are scoring, just not kicking out. My dad did say that all these kickouts went down at once, so my question is does anyone have any idea where these are controlled from, the schematic just list "solenoids" in several places on the power board and such and I seemed to have checked all those places for power, but I wondered if there is a secondary driver somewhere that may have a fuse. All help is a appreciated, you guys are always geniuses.
thanks -Tommy
