Ipad air 2 screen replacement

[robflo1970]

Hello everyone.

I have two ipad air 2 that screen needed to be replaced, so I bought a screen and replaced on one ipad and nothing happened there was no power or image on the screen so I tried it on the other ipad and the same, no power on the screen no image, nothing, so I thought it was a defective screen so I bought another screen from a different company and did the same on both ipad that the screen had to be replaced and the problem is the same, no image no power no nothing, I have changed the screen on my ipad air 2 before a few times and never had this problem. I left the batteries on both ipad charging overnight maybe that was the problem.

Can someone please help me? Thanks
