Hi guys, I have a Club Cops N Robbers Gold fruit machine. Only had the thing 2 days and its packed up. Wont start up, just makes an intermittant "hissing or bussing sound" Tried swopping out the PSU, no joy. Tried replacing the game card from a fully working machine and still does the same. All 4 green LED light are lit on the main board, but the red one flashes. Any ideas?
