We just missed each other .

From your description if everything turns into an horizontal strip at the top then you have a defective lcd panel

Pull the lvds plug either at the main board or t-con and re-insert it without locking it in place then wiggle it while watching the screen , do you still see blinking only at the top of the screen ?

If so then you definitely have a bad panel
