I have two arcade machines that I am having the same problem with one is a primal rage it powers up fine I can hear the sound of the game I can coin up and start playing and everything the only problem which is a big one is there is no picture it is playing blind. when I open the back I do not see any neck glow at all and there is nothing on the screen either. I have the same exact problem with my Rush n attack machine sound and buttons and coin up work great but no picture or glow at all the only difference is with the primal rage I can hear the monitor power on. what could be the problem with these I appreciate any help you guys can give me
