Fruit Machine Chat

Hi, I'm new to this forum and the world of Maygay machines.

The one in question is a Maygay Fruit n nudge.

My first purchase has a problem in that it won't boot up.

The power supply is supplying the various voltages (led's all on) but none of the lamps will light.
The led's on the MPU are on. Could this point to a lamp pcb problem?

I've changed the backup battery on the mpu before it leaks.

MPU : EA 600039 EC 600020

Reel pcb : EC 100017.1

Lamp pcb : DJP 1010.1

Any advice will be most welcome.

What's the status of the flashing lights on the mpu as they should be from top to bottom on,off,on,on,on,flashing. If this is correct I'd start by swapping out the lamp board for a one stop one. This is the board situated at the top of the upper door when opened, kind of above your head directly when standing under the open top door.

Thanks. All fixed now with a new MPU.

Appreciate the help.
