Hey guys,

I have been trying to find a solution to my Pie Factory problems. I am getting the LCD METER COMMS FAIL message stopping the machine functioning at all. 54-2A I believe!

If I unplug the LCD meter then the machine will function with the hatch open, test mode. However it throws a wobbler without the meter if any cash goes in.

When plugged in the meter does seem to be alive. It will say Sec 2a and then go to all noughts.

I tested all the wires to the meter for continuity and the red wire didn't have this (wires are from MPU5 to Sec unit by coin slot), the others were fine. So the obvious suspect was the resistor along the red wire! So I have been out to Maplins and bought a 1000 Ohm resistor for it. To no joy, same problem. The resistor that came off was a difficult one to read though as you couldn't tell which side to read the coloured bars from. It could have been 1000 Ohm, as I got, or maybe other way round and 120 Ohm!

Does anyone know what the correct resistor should be. Or any other possible solutions to the problem would be great.

Thanks

Ian

hello mate

it will probably be the actual sec meter thats faulty.
i have changed quite a few and since they are a sealed unit you cant actually repair the inside.

i can supply you a replacement for £15 inc postage.

pm me if your interested.

Cheers for that,

Do you know what rating the resistor is? It is just no current was passing the old resistor so there was definitley a fault there. The Sec does seem to work but could be to blame.

I am hoping to get another MPU5 machine shortly, as soon as I win a suitable one on Ebay! So I will swap out the sec unit and see if it works in the other machine. I may well get back to you if the problem is definitely the little bugger!

dont know the rating offhand but if you need a sec meter i have one.

Ive had this same problem on my machine, all i did was swop the game card from a different machine so it cleared its RAM, then put the original one back in and it worked fine. Its amazing how many errors you can fix by just clearing the RAM

Thanks mate,

That is actually a really good tip. I tried that and the problem was better. The only problem it has now is with cash entry.

I think in this case it is a knackered Sec unit. But that is a great tip for me, and anybody, with problems. As switching the thing on with no program card, as I did. Doesn't seem to clear the Ram. However this method does. It had clearly forgotten old problems.
