Same thing happened to me -- got it today from Best Buy (32Gb Grey), let it charge 8 hours (power button light was green), tried to turn it on... nothing. Not once did the display ever flicker.
Tried all of the following:
- Regular power on
- Hold power button for 30 seconds
- Hold power for 30 seconds then release then 3 seconds
- Paper-clip reset
- VolDown and Power for 12 second reset
None of it worked, the display never showed -anything-. I suspect either the display itself is bad or the connecting cable isn't connected. 2nd returned TFP in less than a week.
