Alright, so... you boot up, do you see ANYTHING on the screen?

As far as I can understand by your explanation.. you're saying:

After doing a soft / hard reset, your screen goes black.

Does that mean it shows the Nokia toast? (Or android symbol or anything) https://i.ytimg.com/vi/0vHZY0V_BoM/hqdef...

Then just goes black?

Or does NOTHING.. NOTHING AT ALL, show on your screen? (Backlighting doesn't count)

When posting your problem, try to clarify as much as possible.
