Did you change the display yourself or did an authorized service center repair it for you? If a service center did it, I suggest that you raise this with your local support team to check status and how to proceed with this in the best possible way.
Local support.

yes I did it myself but wen I checked in service testing it was okay like values change as light comes.
I think there may blockage in New display so have to remove everything and.check once.
as this phones is not available in India so they don't offer any support.
