Couple things, I will get the manual for you but it will probably be tomorrow as I am headed to work right now, can you hear the high pitched whine of crt high voltage, if not shut off the machine after it has been on for like a minute does the screen flash when shutting it off, if so your monitor if working fine. Do you hear the binging of the game when you first turn it on, if not check the power supplies at the top of the cabinet. One should be 5volts, this powers the game board. The other supply is 12volts, this is just for the buttons and light bulbs, the game should still work without this one but you won't be able to press the buttons.
