Can't say much for your choice of programs. Looks maybe like gamma problem.

So you say it's gamma issue so the only way to fix is to change main board?I thought gamma issues was like this?https://www.youtube.com/watch?v=BieS43QlC6w

Still looks to be a t-con under the shield. So is video showing a red tint? Maybe remove shield.
