HI!
I once had a Mackbook air with a similar problem, but it was the screen and bus

When you turned it on, the screen looked bad, when you connected the charger it "fixed" but what happened is that when you moved the computer to connect the charger the screen "accommodated" and began to work well, until you wanted to adjust it and the image was lost again. On that occasion it was the screen and the video bus.

Doesn't it work if you try to move or adjust the screen? isn't there a point where it looks better?

(Unless the charger is putting voltage to a point that is not powered?)
