Could someone please help me. I tried all those things and even got to the point where i just had to wait for my back-up files to load, the ones that take about forty minutes the very end step. But i didnt feel like babysitting it for 40 min. so i left for about an hour and came back to my unit with a blank screen and it doesnt even show anything anymore. i tried reseting it killing the power and turning it back on. nothing works i can hear something running but nothing is showing up on the sreen. it doesnt even do the rebooting thing anymore its just blank.
