Just replaced my faulty charge port in my Pixel 2XL, powered on and the screen light up at the bottom only without any recognizable image. Only color is black and a greenish, touch screen sem unresponsive as well. Pulled apart once again and verified connectors were seated. Any other possible areas to check or how to test the screen/ digitizer?
The Pixel 2XL screen is surprisingly easy to break when removing. My best guess is that you broke it, and needs replacement.
