I'm getting sound effects, did not think to look at the score but all solenoids on the machine aren't working either. Opened up the back box and there's one blown fuse in there.

To go a bit deeper (i did not mention this before cause i thought it may have been a separate problem), one of the drop targets was getting stuck, not dropping properly, and this caused the solenoid coil underneath to burn out, so i fixed the target (plastic casing in front of it was slightly bent at the end, jamming it). I'm waiting for a new coil, will replace the fuse and hopefully should be right from there, i think .

Thanks for the link Beaky , I've downloaded that manual but i don't think the whole thing is there. I'm only getting about 12 pages, just seems incomplete to me .
