Not displaying correctly after replacing digitiser
Hi. I have replaced 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 party 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.
What is the most likely cause of this?
