I've never heard of a knackered display causing an alarm, so rule that out. I should know, I've blown a couple of displays myself. Makes a machine a pain in the arse to play, but doesn't do the 'Hey, check it out!' routine.

As Baz said it's most likely the MPU5 board. Simple enough to replace, it's all colour coded and requires no unscrewing or similar as everything is push-fit. You could probably do it yourself using a bit of logic, but depends on how confident you are with such things seeing as how it's the first time you've done it. Just make sure the machine is completely isolated from the mains supply (i.e unplugged) before you start.

I'll let someone else guide you through it as I'd hate to describe slightly wrong and have you blow up a new board

Yeah it seems pretty straightforward. I took it all apart today so it shouldn't be a problem hopefully. I'm actually gonna try replacing the battery on the mpu5 before I get a new board just in case it maybe that.

Does anyone know the best place where I can get a decent mpu5 for a decent price?

Thanks for all your help guys.

ebay is the best bet for mpu5's but i wouldn't pay more than £20 for one

It's definitely not the battery - again that wouldn't cause a lockup of this scale. It is possible that the existing battery has corroded and damaged the surrounding area of the board, in which case it'll take more than a new battery to get it up and running.

May be worth calling local suppliers for MPU5s. Very common hardware. Last time I bought one from a local supplier I got a slimline, Tall Genesis type PSU chucked in for £25, couldn't complain - admittedly they were from a machine he had on site which was broken in to, so had the odd speck of glass here and there, but otherwise were fine

If you don't know who your local suppliers are, you can try the Yellow Pages, Yell.com the UK's local search engine - search for UK businesses, I think they will be under Amusement Machine Suppliers or something along those lines.

I was quoted £40 for one by a local company but there's one on ebay for about £13 so i'll get that one.

Cheers for your help lads much appreciated.

yeah i would doubt its the battery.

in fact i dont think i've had a leaking battery on an mpu 5 but then again we sell most of ours after about 4 years.

i had this problem a few years back on a pcb it turned out to b a faulty power supply .. worth looking into...

Check the fuses on the mux5e pcb if there is no display. Make sure that also the 2 fuses are ok on the mpu5 too.

if there is a problem with software the display will still work to give error code xx-xx

I've checked the fuses and they were ok but replaced them anyway but made no difference.

theres 2 lights on the mux one is a status light that should be flashing and one is a 34 volt light i think they both should be lit up green soon as the machine is powerd up

yeah the sequence is 12 green and 2 red which I have been told means the mpu is knackered.
