Reseat all the inter board ribbon connectors and reseat all the IC's in sockets. Do this with the game off and report back 
I wil have a crack tonight and let you know
Niño I re-seated all the connections inside the cabinet. There was a cable that was not connected which leads to a switch labelled "Screen De-Gause" so I connected them. There is no error message visible on the screen now just a pink screen and small black screen in the top corner (almost like a pip)
