iPad air 1 LCD panel
Hi. I have replaced a cracked digitiser, and before securing screws and sticking down I switched on to test. All seemed to be working perfectly so I went ahead, but after securing I had a problem with screen. I had a line across middle where everything above was perfectly positioned, but everything below was slightly too high. This meant I had part of notification bar repeated on bottom and Several rows of image missing in middle.
I opened up again to check everything connected properly, but have caused more problems. Image is repeated and jumping up and down screen, now cannot get past home screen. I think I may have neglected to disconnect battery the second time around and am now concerned I have damaged LCD.
See below images. Starts with one apple symbol then it multiplies over about 25 seconds.
What is the most likely cause of this?
Thanks
