So I have an HTC Sensation in possession that had a broken digitizer. Replaced the Digi and LCD but the LCD won't turn on when the phone does. I've taken the phone apart numerous times, inspecting everything very closely. No connecter ribbons show any damage, the motherboard of the phone doesnt show any damage and i put everything back together just as it was when I initially took the phone apart.
Note that the old LCD did work before taking it apart, and I have even tried putting it back to to try with no luck what so ever.
I hope someone can shed some light on this situation, as I've had this phone in my possession for over a week now and I haven't been able to get it back up and running.
update: phone only powers on when plugged in. ugh.
