My Iron Man shut down last night, flippers went dead and the shaker was permanently rumbling? All lights are working and the pinwoofer too so no problems there. I had to disconnect the shaker from the board to stop the rumbling but since plugging it back in it's totally dead too. On start of game the trough isn't kicking the ball into the shooter lane either so this is dead. There was a nasty burning smell too but as most of you on here know I'm not great at fixing issues, where do we start on this? Any help is much appreciated as always.
