Hi i am looking for a transformer for my psycho beast barcrest fruit machine i was playing the machine fine for a couple of day and then i went to put it on and there is nothink just a small buzzing sound off power supply i noticed some one said about the capacitors and fuses so i checked the fuse and the capacitors are reading ok in circuit so i thought i wondered if any one has a LDV GREEN LABEL TRANSFORMER FOR A BARCREST IF SO PLWZ PLWZ REPLY LET ME KNOW !!!!
Because i think this is what i need to get the machine up and going again thanks cloy.

is there any lights on the MPU. 1 RED LED on MPU-4's and 4-5 LEDs on MPU-5's double check the 12v and 24v fuses and their carriers it's not uncommon to have a duff fuse carrier on the LDV supplies. also ensure the carrier seats firmly and securely in its holder.

ensure the power connector from PSU is firmly connected to MPU
a small buzzing sound is quite normal for these supplies when they are under load. if it is very load though, you may well have a short-circuit within the supply and a replacement will be needed. you could go to a local amusement machine supplier and they may sell you one from a scrapped machine or direct you to someware you can lay your hands on one. hope this helps.

While I can't recommend it to everyone, I replaced my Green Label LVD PSU with a much newer slimline PSU from a New Genesis cab, as the pinouts were the same.

Seems fine, not given any problems since. As I said though, I'll leave it to you to check the pinouts of your PSU with any replacement you may find, best of luck

hiya thanks for the advice i will check again i found the fuses wrong and i am going to replace the all with the correct voltages and then go from there but could i change my ldv trnsformer for a newer type and would this still work as long as it is barcrest type.

Hi there the Green Label Barcrest PSU mean basically that payout voltage has been dropped from what used to be 50Volts for the payout solenoid to now a 24 volt Hopper unit and so the green label power supply can be swapped over to the new style switch mode unit with no problems as Barcrest have kept the same pinouts on both types. Yellow label power supplies are putting out 50 Volts AC for the payout coils, thats the difference

Hope that helps you out !!! Bridge Rectifiers in the Solid state PSU's like your green label one and in Yellow label types as well tend to go short circuit and the capacitors going bang is about all there is to go wrong with those types.

Switch mode is a bit trickier as you have generally one fuse thats the mains input fuse and thats it !!!! Nothing really servicable inside unless your good or know someone who can fix it !!! A good TV shop should be able to sort it out though !!

ok thanks for the info everyone so the new psu are called the yellow transformers ,Will the capacitor actually go bang as i didnt hear anythik when i turned it on.i will test all the component again out of circuit and hope i will find two capacitors and the rectifier blocks not reading.thanks i will let you know how things go.

Well my barcrest psycho beast is blown on the main mpu5 board i replaced all the fuses and now it is smoked. so if any one is looking for a barcrest for spares give us shout make me a offer but you have to take away plz if not i will beak it up and sell the parts that does work.Ohh yes the psu is all ok now everythink seems ok but i dont know why the main board caught fire.and smoked.im gutted ...

You've got my sympathy. I've caused minor f**kups which I've always been able to sort out (although they've caused a bit of stress sometimes while I retrace my steps) but I've never blown a mainboard before.

Ouch.

thanks bencrest for advice,but i think i will call it a day with this one now i dont want to keep spending and spending so i think i will look for another machine, but i dont know weather to go for another barcrest or somethink else has i do have spares.thanks thou everyone it is great to have this site.

[Bencrest]

I'd stick with MPU5, very easy to work with (normally!) and loads of spares about - plus the spares you already have!

I was so fed up with it next to me i broke it up yesterday i litterly scrap it right done to every nut and bolt i have kept the screws metal alloy and bulbs wiring and buttons but all the rest is gone .
