Since no answer has been accepted yet, let me share my experience:
A/ First thing I try is disconnect then re-seat the Display Cable on both ends (using [guide|13728|this guide]): on the logic board and on the LCD. Then secure the connectors with Kapton/Polyamide tape.
B/ I test the contraption by:
1/ Gently re-seating the LCD back in place then flipping it again out of the back-case. In other words, I am causing the display cable to twist slightly and gently, and putting light stress on both connectors, to see if the change in hue occurs again. Please be gentle ;)
2/ Tapping slightly on the back of the iPad, especially around where the display connectors are located.
C/ If steps 1 AND 2 cause absolutely no change or flickering, I re-seal the iPad.
D/ If steps 1 OR 2 cause any kind of change in hue (ever so light) after or any kind of flickering, I change the display cable.
E/ I test again (repeat B)
F/ If steps 1 AND 2 cause absolutely no change or flickering, I re-seal the iPad.
G/ If steps 1 OR 2 cause any kind of change in hue (ever so light) after or any kind of flickering, I change the LCD.
From experience, 95% of cases are resolved without having to change the LCD.
