does anyone even have an answer for the problem yet. i have the same problem, i have the matrix and a v1.1 xbox.
ive aligned it correctly, test mode flashed green for a split sec and then red afterwards.
but when i power up the machine, its turns on, then off, then on, then off, then on and the led around the eject button flashes red and green.
my motherboard is definately not dead, there is no problems with it whatso ever as i have made no mods to it. i havent even tried using xbox live.............yet.
so whats the deal?
