So I had my newer (to me) Haunted House (#hauntedhouse) just sitting in the "on" position for much of the day, has the Pascal PI-80 board, had a few issues but worked them out (biggest being a bad transistor on the board), machine has been 100% reliable for a few weeks, and SUDDENLY all of the displays went out; I wasn't even playing or touching the machine. I tried reconnecting everything, checked the F3 fuse, tried unplugging everything another 5 times, tried it again the next day, no luck, but did find lots of helpful hints on the forums (including this thread).

Ultimately I was able to determine that the AC power coming into the board (A2J1) at 60V was good. The Pascal board consolidates the power board (A2) and other boards into one, so that made the troubleshooting a little different than some of the older materials I found. But testing the A2J3 output from the board kept giving me basically no voltage readings at all (and I'm fairly stupid using a DMM, I used two different ones including an automatic one, made sure I had ground correct, set to DC in the right range, etc, and NOTHING, nada, not a volt). Lo and behold I saw the word "FUSE" written on the board, and it had a line pointing to a round thingy (yes my lack of technical expertise shows!), and sure enough I popped that right out and learned that was a tiny little fuse, which I don't think shows up on any schematics since it was not part of the original board design. Tested continuity, and I was thrilled to see NO continuity, meaning my issues seem to be caused by the little "sub-mini" sized .125A fuse. Further reading showed that the boards shipped with an extra one of these, but since I was not the original owner I did not get the extra fuse with the board. So I found one on eBay for a few bucks, and next week should be up and running.

So long story long, IF your displays suddenly go out AND if you have the Pascal PI-80 board and you leave your machine running all day (and in an upstairs area that was in the high 80s, so after a few hours things heated up I'm sure inside the machine), it is very likely just a simple little fuse ON the actual board (see photo - look for the word "FUSE", follow the line to the upper right, and that black round thing sitting on top of the white thing is the fuse and pops right off). Hope this helps someone down the road. Happy Haunted Housing!

V1.2 and older Pascal PI80 uses the fuse you linked to (which is fast 100ma), V1.3 uses fast 125ma. Info is on Pascal website where you order spare parts. Worked like a charm, man what a relief to see the displays back!

Oh fantastic, I hoped my post could help someone, yeah it seems the issue must be fairly common since there are extra fuses included. I haven't had any hiccups since my post, but good to know if they go out again that there is a quick fix to get back up and running! Anyway, glad your party guests didn't have to miss out on HH

Dang that sucks, I have not left mine in for longer than a couple of hours since my fuse blew either. Makes me wonder if the board could use a slightly stronger fuse? I know they slightly increased the size as they revised the board. I normally would never even consider that as a potential fix, but in this case perhaps they were too conservative with that part of the design.
