touch screen not working (even after replaced screen/digitizer)
Two weeks ago my iPad stopped responding to touch (as far as I know, nothing happened to trigger this. I didn't drop it, it just stopped working). Tried restoring. Nothing.
I bought the screen/digitizer/home button ifixit part and replaced it last night. Thankfully the power & home buttons and screen still work after the replacement.
Unfortunately, the iPad still does not respond to any touches and I cannot slide to unlock. I tried a DFU restore this morning, and that did nothing either.
It didn't look like anything was wrong with my original screen/digitizer and it doesn't look like anything is wrong with the replacement.
Are there are other things that could be preventing the iPad from receiving touch input? Anything that I can try fixing?
(before I tried these repairs, the genius bar only was willing to replace it for $300).
I'd love any suggestions. Thanks.
