So previously I made a post that my funhouse has a bunch of issues and melted all the controlled lights into puddles of plastic.
Well fast forward to a couple weeks ago, I had my bride of pinbot at the Rocky Mountain showdown and it died on me at the show. I needed a MPU so I pulled the one from funhouse to make it through the show and everything was fine for the remaining time of the weekend. So yesterday I finally had time to set up bride and see what I could figure out with the original mpu. I set it up, checked everything out and turned it on.
There were only like 4 lights under the pf that were on and even those few were dim and flakey. I checked the plugs on the board and the related transients to the rows and columns and everything was fine. So I started looking at the LEDs and found that they were melted just like the ones I had in funhouse.
Common denomintor: the Rottendog MPU089. Before anyone says they are crap boards, I get it, but that’s what was available to me and I have had good luck with other rottendog products. Let’s try to just troubleshoot this instead of bashing the boards. There has to be a fix or logical explanation for why this board is melting LEDs. I’ve had rottendog mpus in other wpc games without any issues. I’m pretty sure this is a specific board problem.
