Chosen Solution

i recently replaced the glass/digitizer on an ipad 4 wi-fi model. when putting it back together I noticed that the righthand side of the LCD was darker than the other 2/3. I cleaned the contacts and tried two other known good working LCD screens with the same result. I am not sure what the issue could be! I have not put the known good working LCDs back into other ipads to see if something happened to them but either way its just not right. I have spoken with other technicians who have had the same issue and do not have an answer. Please help

I have the the exactly the same issue, right side of the screen is darker. It was even an company that changed the screen. They claim that its my fault. That I must have droped on my way home. An unfortunate I didn’t chek it before I came home. Any solution to this problem?
