Just purchased a 2007 Golden tee live 2007 offline edition, original problem on the machine was that the screen was scrambled, got it home checked out the I/O board it looked good visually, then plugged in a monitor to nighthawk directly and got a screen that was very jumbled but could make out some text, saying video ram failed, any ideas? i did mess with the dip switches also, when i removed the board and reinstalled the arcade monitor is no longer scrambled but is a blank screen, was very careful with the board.
