First post here. I am pretty good with Apple Product repairs, but this one has me. I bought an iPad 2 with a non-responsive TS. When it arrived it actually worked - once, and then stopped working again. I removed the old one and connected a new one, same fault. I tried 2 other brand new touch screens and still the same. I have restored the pad with IPSW 6.1.2, still the same. The connector sits perfectly, and the clips are in place and down.
What else can I try please? I'm guessing a board fault?
Many thanks in advance.
