Built a 128 xbox. when i plug it into my projector on my theater room i see wavy lines scrolling diagonally across the screen but not with another xbox of mine. i plug both in with s-video (nothing better available).
here's another weird thing about this, it shows the wavy lines if i select another input on my control center. so if i put my a/v switch box (control center) on DVD and play a DVD with the xbox on that is plugged into a different input i still see the wavy lines while watching the DVD till i turn off the xbox.
any ideas? could be a grounding issue pushing current into the control center? i put the xbox directly on top of the control center. maybe a shielding issue? i dont have the RF shields on either xbox.
the lines were hard to capture on camera so i drew a thick black line on in photoshop to show the angle of the lines. the direction and angle constantly change and scroll around some times fading away and coming back.
