First of all, I hope I started this in the right place, I am new to this site. A week ago I traded a half broken Ps3 for a broken English Mark Darts arcade game. My assumption was right and the power supply was burned out. I replaced both rectifiers, the 12 volt voltage regulator, etc. I was excited to get it working, but no luck. I have been poking at it for days without results. Yesterday I plugged it in to check for AC ripple and I smelled something burning. I quickly unplugged, and to my disappointment the transformer is burn up. I am using a computer power supply to get things working, almost everything works. The machine doesn't recognize that you put coins in, and the amp doesn't work (The amp doesn't work because lack of 21 volt input). I don't know what to do at this point, does anyone else have this game that doesn't recognize an coin input? Anyone have any ideas?

The game pretty much locks up if you've got a contact closed on the dart board. Make sure that isn't too tight. Without sound, you wouldn't get the telltale alarm that it makes.

I feel really dumb, but I found that the grounding wire to audio amp also goes to the coin board. The coin board is now functioning. I also discovered the computer power supply outputs enough voltage and current to power the amp, so the game now has sound. Thank you for the response though. :D
