Cracked screen with lower half responsive
My Xperia Z was knocked on to wall with its corner.
And there's a crack inside the phone.
The outer glass/screen is not cracked, its the inside.
Cracked hairline area aren't responsive, but lower half ( non-damaged area is able to respond to touch )
I've seen the repair guide for XZ in this website, and the guy is only replacing one part ( touchscreen and lcd display? ).
I'm not sure which parts should I buy to replace the screen myself.
Or should i get this full set, which is expensive?

Or please advice on the parts.
