Hey I boot up, shows blue x, can hear sound but then no video, if i hold the power same thing, i push up and down on the controller but no sounds, so I think it just stops there, i have an xecuter 3 and xapter. Happened after I was in xbox media player, messed with some display settings, NTSC-M/J and PAL, said restart to change settings, maybe I messed up one of my displays... How does the xbox remember your settings, is there a cmos batt on the motherboard i can take out orrrr I'm just at a loss here anybody had similar problems? Did I fry my chip? my xbox?
