just got a bsd that was on route in a bowling alley so that means as long as it made noise did a few things and accepted money it was in great shape. fixed multiple connector problems and reflowed light boards for cold solder joints. have broken opto 56 led burned out and receiver eye missing off the board have no idea how that happened. board also shuts down at irregular times, seems to restart when I press board near eprom or nvram or memory area. going to solder in that area to see if cold solder joint causing problem may have something to do with my current problem. The current problem is that while playing the game and entering video mode the flippers of course are disabled. the problem is that the flippers will not renenable themselves after the video mode is over. I have even had another ball served up to me after loosing the ball I was on and the flippers are still disabled. could this be a problem with bad connection to eprom or memory or is the eprom having its own problems?
