I know this doesnt help anyone else with the same problem, but i to suffer from this.
I have a v1.3 xbox, an X2 lite.
I have never had any problems with my xbox, but when i moved house a month ago, and since then I have also been having problems.
When I turn the xbox on, it resets it self 3 times, on the 3rd reset I have a blinking red and green light and no audio or video output.
The thing with this is that it is intermitant,
When i diable my x2 chip using the swith that came with it, I get it booting into the MS dash fine ( HDD LOCKED ) and I can use normally.
Im assuming there is a fix for this, but I can not seem to sort it.
I have checked all my connections, D0 seems ok, ltp points look ok, usb connector is ok, and looks like the power to the x2 is ok.
But clearly i am missing something.
any help would be appreciated.
