Of course, in this case, base what you do based on your age, experience and trust in your parents. I chose to take the repairs on myself without permission since I did not trust the response from one side specifically after an authority power trip incident and threw a laptop out on me as “punishment” thinking I’d take it lightly and cave to his absurd authority trips and abuse of it. Guess who realized he screwed up hard later on when he created a permanent boundary ever since? Yes, it remains to this day.
It’s because of that incident why in most cases I was dealing with something that’s mine (in which case, I always settled it with take a hike) 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 older devices that weren't easily repaired (or totaled out cost wise) that way if I needed a part I hopefully had it and purchased based on cross compatibility. Ever since he decided to be that way, I’m firmly in the “beg for forgiveness” camp if the circumstances and skillset match. Part of how I handle answers today is based on that principle if I can tell the OP can potentially handle it.
Note: I don't bother with that in purchasing anymore as an adult; if I want a 4K panel on the replacement laptop and my old one is FHD, I’ll buy the 4K version even if I have to switch brands.
If you can handle it, we need to know what the model number of the device is to get an idea how much the parts you really need will cost - for example if the LCD bezel is mostly intact besides a few small splashes then I would probably leave it be unless it was severely damaged. 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, then you can do so and defend yourself in the extreme worst case. If it devolves there (hope it doesn’t), stand your ground the moment you do and DO NOT BACK OFF or apologize. If you cave and your reason was legit, then it enables the behavior!
Things happen, and what you did was a silly mistake, but you sometimes have to learn the hard way sadly. Consider this a lesson about things like nail polish remover being particularly bad to keep around devices, unless you do not care, or you can repair it yourself. I've kept it around my equipment, but I never leave it near a laptop for instance… Or at least make sure I can get back up and running, or if it's on the retirement list decide what to do.
