I have a WD TV live and suddenly it stopped working(power led keeps flashing on and off). I was using the original firmware (i do not know the version)
I did a little bit of research on the mighty google and found this site. I hope i posted in the right section.
I managed to connect a BusPirate to the COM port to see how the unit is booting .
Below is what I received from the brick:

Any ideas what can be wrong? is it a software issue or could it be an electrical defect. I measured Voltages on the board and there seems to be ok: 5V, 3.3V and 1V (not sure about this one... what device needs 1V?)
Thanks in advance!
