Hey fellows,
I've been trying to work through this issue with Stern, but they have been taking FOREVER (originally contacted them probably 2 months ago) to respond to me, so I figured I'd post here and see if anyone has had a similar issue. My Iron Maiden Pro will occasionally go into an error mode which says "check power distribution board". I have gone over the board and fixed what looked like possibly maybe cold solder joints, and checked that all the pins on the plugs were seated properly. Stern did respond once and suggested that I reinstall the software, which I did, and it worked for about 2 weeks and went into the same error mode. It's no big deal really, as a reboot will fix this, but it's a route game, and I'm trying to avoid future service calls.
Another interesting thing I noticed is that while it's in this error mode, the attract light show continues in extreme slow motion.
