Maybe it just needs a little vacation lol!
So, I water damaged a laptop years ago, and while i didn't kill it, the repair shop said it was likely some corrosion would eventually cause problems and it could break in the future without notice, and also my monitor had a damaged area in the bottom corner about the size of a credit card. You could see things there, but the color was really distorted.
I needed a solid and reliable laptop for work as there was real time stuff it was used for where failure would be catastrophic so I got another one, but I still used the broken one for various things.
Well, to my surprise, like 5 years later (after repeated low but yearly use), I turn it on to test some software on the older operating system, and the fucking monitor is perfect, no longer distorted.
Clearly it just needed a vacation!
