Haha how embarrassing. Thank you, one of the fuses was gone.

Funny when I was trying to work out what it was I actually changed the 3 magnet board fuses as they looked dodgy, but neglected looking at the others,

Although its working when I turned the game on I noticed a low hum (I did previously too). I'm wondering if something is stuck on and if I leave the game on long enough it's going to blow another fuse.
