Both screen and sound failed

Last year my gameboy color was dropped. Very, very hard. The screen was cracked, leaving a large area of dead pixels, but it was otherwise in fine working condition. This morning, I turned it on, and the screen was completely dead, no signs of life, and the speakers sounded muffled. I plugged in headphones and the audio sounded fine on them. I plan on replacing the screen and the speaker, but should I also replace the capacitors for the speaker or maybe the sound amp? I’m not super experienced with soldering and I don’t want to take any risks I don’t have to, I just want it to work how it did before it was broken.
