Help with Totem that is acting up

[Tcooper]

So my totem has decided to act up and wanting to know where to start looking.

The machine powers up fine up, once I start a game after a few seconds the sounds goes crazy then all gi shut off and loose power to flippers, almost seems like the game tilts. The game stays like this until powered off, the the cycle begins again. Please point me in right direction as I'm pretty new and just learning, thanks

Check the +5Vand -12V supplies on the MPU, arriving from the power supply.
Looks like the +5V is not stable to the MPU.

The harness/pins power supply-MPU, the small +5V potentiometer adjust on the power supply,
and the harness/pins MPU/driver are often in need of attention.

Thanks a lot, you were exactly right, fixed the weak connection at +5v and she works as good as new again, much appreciated!!!

I gotta say... you may not see Sylvain post here very often... but when he does, it's always helpful and usually right on target!

Congrats on the fix
