Beaver Las Vegas fault

Hi there everyone...

New to these forums cause i'm looking for help with my GLOBAL Beaver Las Vegas machine. I just bought it recently, second hand. Worked fine for about a week and then wouldn't switch on properly.

At first it started cutting off in the middle of playing and the speaker would make a clicking or cracking noise as though it was constantly trying to restart itself.

Now after abit of time of it occasionally working and cutting off when playing it won't come on at all.

Once I plug it in the alarm light flashes and thats all, the reels don't spin or anything?

Does anyone have any advice, i'd be very grateful. If you'd like anymore info on the problem please just let me know. I can even record a quick video of me plugging it in if anyone thinks that might help.

Thanks in advance...

if the machine has the black metal mpu inside there is a good chance the +12v is down,If you check the plug that supplies the hopper(its next to the red power lead,bottom right)you will find the outputs ie +12v,+24v and +5v(i think)and if you have a meter and you measure the 12v you will probably find it is low, and this will cause the reset and crackling on the speaker,the problem with these One Stop mpu's is that the AC voltage is rectified to DC voltage on the board and the components fail and burn out easy,hope this helps

Thanks so much for the info Lee but being new to the insides of my machine i'm abit behind on the terminology.

Could you tell me what the MPU is and what would you suggest I could do?

Sorry if i'm being a little awkward with this...

The MPU is the large main board.
Check that the battery has not been leaking as this will damage the board's circuit tracks and components!

These PSU's are notorious for packing up, check the circuit board in the PSU for dry solder joints and overheating or scorching of the terminals.
The capacitors in the PSU could probably do with replacing.

Thanks for that... Do you think it might be worth me trying out a new PSU? If so would I need a specific one for my machine or can I just use one from any other machine?
