This model number you have posted doesn't do anything for me. I am lazy, research sucks.
Is this game a countertop or an upright?
Is it a Megatouch 1-7, an XL, or a MAXX?
Regardless of game type, if all you have is a monitor problem you should still be able to play the game 'blind', that is, when you touch the screen you should get a response acknowledged by a sound.
If you have no game boot up you can tell if the monitor is good by watching the screen when you turn off the power. It should quickly flash white.
