[AC Question]

Only minor cracks say about 4 in total . The cracks r independant of each other . Ie they dont touch each other . Im hoping my lcd digitizer is still ok and suggesting i may have other problems ?

Well, that it flickers like that would indicate to me that the cracks in the screen have compromised the glass. Something is putting pressure on something inside the panel enough to cause it to fault. I have a feeling that whatever it is will most likely fail, outright, at some point, leaving you with a dead display.

You might want to get that thing into a repair shop to have the display replaced.
