The screen was cracked so I had it repaired. When I got it back the screen looks great and all the buttons work but only half the touch screen works. What do I need to replace now to get it to work.

If you had it repaired, you should consider having the repair shop fix it again under warranty otherwise you’ll end up spending your money twice. If you want to try it yourself, then you can find the replacement part here and the repair guide here.
