Hey, I'm new with mod chips, I just put mine on and my xbox is already broken. It was working fine for about 2 days. I started messing with the settings and now the picture is in black and white, I have no sound, and the picture keeps jumping off the screen... sorta like a broken tv. I think I changed pal pr ntsc to something else. Please help I don't know what to do. Maybe is there is a manual restart or something that will totally start my system over. Please help.
