I have a Sigma Cash Bonus poker machine. The manual I have says it's a PT-2/2B. I think it's about a 1984 year. I moved it to a friends house. He called and said it wasn't working. I know very little about these things but went over to look at it. When I plugged it in, it powered up, cycled the BV...all normal, but then it restarted itself. No different than if I had shut it off and back on, and kept doing it over and over. I opened it up and checked for loose connections (with it still on...I know probably not smart.) When I wiggled the two pieces on the board circled in the two pics below, it seemed to work fine. I did this only an hour ago so I don't know if it acted up again yet, but he said it happened twice in the last week, sometimes in the middle of play. After he shut it down and let it sit a little, it worked fine for awhile. So my questions are: What are the two pieces circled? Could this be the problem since it was moved and may have jarred the two "clips"(?) since it worked so far after I pushed them on tight? And if that may have been a coincidence, what else should I look for that may cause the machine to reboot continuously like that? Thanks for any input anyone here can give me.

  It is VERY possible one of the three "legs" on thouse transistors has a weak or broken solder joint... When you pushed down it made better contact.

I had a similar problem with one of my Mikon Progressive signs where the display would put up all sorts of strange characters after it warmed up or if I applied any pressure to the transistor on that board .   Burning Resistor

   All I did was reheat one leg at a time just enough to melt a little extra solder on and have never had a problem since.

Thanks Thor...Are the clips on top of them a heat sink of sorts?

Yes, those ARE heat sinks to help dissipate the heat coming out of the components.
You may NOT have to remove them to put a little solder on a broken leg though...
It's not necessary to take them off.

Thanks. That's what I fugured. One of them had a patent # on it so I did a search and found it.
For anyone feeling nostalgic... hyper

That's a great way to find out what things are! applause
Amazing how they stick that big heat sink on 3 tiny little legs huh?
That whole component combo was liable to bend over and "bust a leg" so to speak!
