Strange screen OLED

[impy101]

I have a modded OLED switch here that has a very strange problem. The color on the screen is overbrightened or something. See the photo to see what I mean.

Any idea how I can fix this?

Look at the display Pinns or the connector maybe it´s not slided all the way in

Seems like a ribbon cable issue to me too, either it's not inserted properly or it got damaged during modchip installation.
