Weird screen issues - black or noisy

I recently received a broken Samsung Galaxy A52 which had a completely black, dead display, however I could feel vibrations and hear the alarm at 5:00 AM. I bought a new display, however when I connected that all it showed was a bunch of noisy pixels, as shown below:

I cleaned everything with alcohol, inspected it under a magnifying lens and didn’t find anything that could cause this issue. Apparently the person I got it from through it out of the window when he couldn’t turn the alarm off, so I’m thinking it’s a logic board issue and there’s nothing I can do with it, but please correct me if I’m wrong.
