Hi Kevin, First, I am assuming that you tried on the new digitizers without gluing them or pushing them hard in place? (To rule out a creased digitizer cable due to improper installation). Second, did the iPad show any signs of drop when it came back? Any sign of liquid damage? Note: did you try a restore? (Asking if you did, not suggesting that you do). After ruling out the above, I'd use a magnifying glass to look at the touch-screen connectors on the logic board to see if: - The retaining flaps are missing, broken, displaced; - The connector is damaged, any pins are broken; you could even test continuity between the connector and logic board; - Any components around them are missing or broken. Have a look and let us know what you see. We can take it from there.
