first of all, the unit was working just fine , but suddenly the screen became totally black, no white dots appearing at all !!!!.
So as your suggestion :the screen could be disconnected from the main board, but this is impossible !!, because I'm taking care so so much than what any body could Imagine ..
any way I'm wondering if this problem happen to other users like me ! . one more thing : are you sure about the power connection of the screen if this screen disconnected from the main board it will become black !!
Thank you for your time to help me . .
