The Houdini machine I recently picked up has started, for lack of a better word, rebooting in the middle of a game. I've noticed it happens when the score is approaching 1,000,000, so lots of things are happening: multiballs, tricks, jail escapes, etc around the same time. Screen goes blank, then game goes dark, flippers don't work, etc. Like it's got too many things going on for it to process. Then it resets a lot quickers than when it initially boots up. I noticed when it first shuts down, the screen says something to the effect of "HDMI no signal" or something similar. It didn't do this when I first got it, despite scoring several games above 1,000,000, but now it's done it twice over 2 days. Seems like a computer problem, as it acts similar to a computer when they sometimes just reboot on their own.
What's the best way to approach this regarding diagnosis, repair, etc?
thanks
