Aw, Here It Goes!
My 360's been acting up when I turn it on, the screen stays black, but the system turns on and I can hear sound and when I press buttons on the controller it also works because I can hear the sounds when I scroll up and down the Dashboard. I've tried it on three different T.V.'s with similar results. I believe its the component cable thats faulty but audio still works. But im not sure how to fix it.
