I spilled acetone (nail polish remover) on a laptop screen.

Of course, in this case, base what you do base on your age, experience, and trust in your parents. I chose to take the repairs on myself without permission since I did not trust any future responses from one specific parent after his power trip when he threw a laptop out on me as “punishment”, trying to scare me into being complicit in his problems.
I think you can guess how quickly he realized he screwed up hard when he created a permanent boundary I will not let go of, even if a therapist begs me. To this day, I infamously I keep his old laptops he throws out as "karma" 13 years later, unapologetically. His old devices being turned from scrap to fixed have a special "FU, you made this real" appeal, so much so that I secretly fixed his broken P3 XL for me.

That incident was why in most cases I was dealing with something that’s mine (in which case, I always told them to shove it) I’d repair it myself especially seeing as most of it was old OOW hardware with easily interchanged parts. I sustained it by holding onto old "BER" devices that weren't worth repairing. New/new to me devices were based on the parts bin for years. Since then, I am firmly in the “beg for forgiveness” camp (if the circumstances and skillset match). This is what I base my answers on today.
Note: I don't bother with that in purchasing anymore as an adult; if I want a 2K or 4K panel on my new laptop (and my old one is FHD) I buy it that way.

If you can handle it, we need to know what the model number of the device is to get an idea of how much the parts you really need will cost - for example if the LCD bezel is mostly intact besides a few small splashes I would probably leave it be unless it was severely damaged or hide it with something like a semi matched nail polish or other paint. If it’s severely damaged, then you may want to replace it too.

If you can’t, make sure you discuss it in an environment where everyone will be mature about it and if you have to push back due to poor parental response... do so and BE PREPARED TO DEFEND YOURSELF. If it devolves there (hope it doesn’t), stand your ground if need be. DO NOT APOLOGIZE for self-defense over an honest mistake and a poor reaction. It will vindicate the bad response! Things happen, and it was an accident learned the hard way.

Consider this a lesson about things like nail polish remover being particularly bad to keep around devices (unless you do not care if it gets ruined, like a really rough device on death's door anyway). I've kept things like that around my equipment, but I never leave it near a laptop for instance without a cap on.
