1980 Spider-Man Solenoid Problems

[bgrom8]

I was hoping someone could help me with my pinball problems. I have a 1980 Gottlieb The Amazing Spider-Man pinball. What’s happening is I turn the machine on and it will play fine for about 5 minutes or so. Soon after, the solenoid for the 2 kick outs and the solenoids for both sets of drop targets will reset but only half way. The targets come up too high and do not drop back down to a level where a ball can knock them and the kickouts only come up and do not go back down unless I push them. I am not sure but think that the problem may be related to the 3 metal things on the green board (transistors?) because they get really hot after the machine runs for a while. When I shut the machine off after the problem has started I can hears what seems to be solenoids going back to a relaxed position. Sorry if I’ve confused any lingo as I am new at this. Any help is greatly appreciated. I’m posting a URL to a video of the problem as well. Thanks!
