Replaced LCD Screen and images aren't exposing

On mobile so sorry if the formatting is an issue

I posted in the resin printing subreddit a couple times to figure out the issue with my Saturn 3.

I just replaced the LCD screen following the video on YouTube. I'm pretty sure I put everything back together the right way, but i'm new to this. So who knows. I also haven't updated the firmware so if that's the problem, please tell me how to do it.

The only thing I haven't done is put all the screws to the body back in but I wanted to make sure the exposure test was working before i had to take everything apart again in case something else was wrong so if i'm an idiot, just let me know
