I'd change the Alpha Display and see if that solves your problem. You should be able to get one off e-bay no problem. If the machine is giving random errors or problems, I would try changing the MPU.

Hi guys,

I couldn't wait for the new MPU5 Board, so I tried the one from my X-rated machine, its happy days, the machine has been running for hours now, without any problems.

I have taken the outer case off the MPU, that came with the Sub Zero machine and just above the payout connections, at component locations "CBAR1" "TR34" "TR33" "TR32" "TR31" you can smell burning, so taking a guess, I'd say a component at one of these locations is causing the "OPT 100P ALM 01" error.

Check the block connections in the machine first, if you havn't done so already. If still no Alpha Display, the machine may need a new one. I will point out though, the Alpha Display may not be to blame. It may be a fault with the Mux Board or MPU. Fruit machines are funny things and not always straight forward, I'm finding this out myself at the moment.

Hi guys. I'm new to the forum, so hello to all.

I think this Sub Zero machine is the one I won on e-bay the other day ( suffolk area ). I'd just like to update anyone who is keen to learn what is causing the problem. I can confirm the Mux Board is not causing the "opt 100p alm 01" error, on this machine.

I already have a Red Gaming "X-rated" machine, in full working order. I have tried the Hopper, PSU & Mux Board from this machine in the Sub Zero machine, and still the "opt 100p alm 01" appears within seconds. One thing I've noticed on the MPU5 Board, is that the +24v L.e.d goes out when this error occurs, also, the status L.e.d constantly flashes one green & one red. I'm waiting on a new MPU5 Board to be delivered next week, so I'll be back soon with another update on this issue.

Another issue with this machine is, when you have both doors closed, the machine at startup, tries to payout £1, "I.O.U £1 call attendent" or similar is displayed. Should this machine be doing that?

Thanks in advance to all who may reply.
