Phone screen damaged after repair

I've just finished replacing the logic board in my dead galaxy s9. Prior to replacing it the screen was perfect.

After putting it back together, my screen has a bunch of LEDs near the bottom that won't display blue colors at all.

If I'd have to guess, I might have heated the screen too much when trying to remove the back cover/battery.

Question is, does anyone know any way (dumb or risky to the screen itself) to try and fix this situation other than buying a new screen?

Thanks.
