Removed camera and microphone assembly and now screen is too dim

I carefully separated the frame from the backplate to about halfway down the screen. Then with tweezers, I removed the cable from the port on the microphone/camera assembly bar. Seemed pretty straightforward. I then snapped the frame back in place.

I can tell everything is working normally with the os upon powering back up. However.. the screen is extremely dim. I can just barely see the Lenovo logo and then it’s too dark to see anything afterwards.

I’m assuming that part of the assembly I removed is the lighting for the screen? I really want to leave the camera and microphone out of the computer. What should I do to get the screen illuminated again? The brightness function buttons don’t appear to be doing anything now.

Thank you
