Ok, here goes..
I have been useing my xbox(1.6) for monthes now. I have it modded by using xboxhdm(I beleive its jsut an exploit mod) I have been using evox as the main dashboard.
Yesterday, I finally got my cord for my HDTV. I hooked it up and it was "working" (screen would flicker loading a few programs, nothgin big) Well i noticed that for soem reason, whenever I installed evox, it does not let me load into the M$ dashboard to change the screen resolution. so i was looking for alternatives to get my xbox to display in Hd(for other games) I downlaoded avalaunch, and it has the option within the settings. However, whenever I tried to edit the display settings changes it informed me that "cannot write to Locked Harddrive" So I was like, ok lets unlock the harddrive. I downloaded configMagic or whatever it is. I unlocked the harddrive. and after it was done it told me to restart. I did an "in game reset" and it sent me back to the main screen of evox. I then went to my file manager and opened up avalaunch again. I went to the settings, changed the display settings, and this time I got the error "unble to change settings to eeprom" this time I said screw it.. I did another in game reset, it sent me to evox.. I played THUG 2.. (didnt really notice that much of a resolution change) and after I was done.. I totally shut down the xbox
about a half hour later.... problems.
I boot the xbox up and no sound.. no display. the LED on the front it green for like 4 seconds then flashes red and green(frag)
I shut it down.. and turn back on
same situation.. no display.. no audio.
I try conencting my origional a/v cable, thinking the no display could be caused by trying to use my HDTV cable..
I did not hook up to the TV with the alternative connection, but when I powered it on.. same light pattern.
what I have tried:
since this happened right before I went to work, I didnt get to spend that much time with it.
I loaded my xboxhdm bood disk in the computer with the xbox harddrive in it. My computer immediatly saw the harddrive when passing POST. (So I think that the hard drive is unlocked, cause i dndt need to hot swap it) The cd booted up, but because the only computer that I was able to get my hands on was a 300mhz w/ 90mb RAM It wasnt able to run the CD(cd loaded about 1.5 files then the PC resetarted)
I am hopeing that the problem is with the harddrive, as I heard that the TSOP in the xbox NEEDS the HD locked to boot up, unless you are useing a mod-chip(as i am not)
But I also noticed that the 1.6 motherboard does not have a TSOP in it. Soooo... also I was wondering that if it WAS the harddrive, shouldnt I have at least gotten some sort of display?
Im almost starting to think that it is the motherboard. but like I noted earlier, I really didnt do any modifications to the motherboard itself. but the no display/audio is a little scary.
Thanks in advance for your help., and sorry for typos.
