If you get a picture, then the wires are probably bad. Reply to argeru m 0 l i7Baby a b D Laptop April 21, 2014 5:31:08 PM Probably CPU not working. Or maybe screen gone. Or maybe cables between screen and keyboard damaged. If new, then return it for refund or replacement. Else take it in for repair.
