Sadly no, the marks are still there, and haven’t been motivated to try to fix yet. I’ve seen some videos online where people can coerce trapped isopropyl alcohol out without having to take a screen apart, but have been hesitant to try out some of the methods.

@craiglloyd I did an embarrassing amount of spudger prying pretty much everywhere along the top/bottom of the battery, I actually broke a few spudger tips in the process so that might reveal something about my approach…

But, I’m starting to think it may not be LCD damage after all, but rather some isopropyl alcohol caught behind the screen– During my prying, the Switch case was getting pretty heavily warped, so maybe some of the alcohol (that I definitely used in excess) slipped in and got sandwiched under the screen? I started to notice this since the blotches seem like they’ve moved over time. Here’s an image of the screen now https://imgur.com/DjYmFnJ (and the dark gray blotch along the leftside isn’t a shadow, white spots in bottom left I thought were pressure damage)

It’s still very usable / not noticeable on black colors and thanks again for the guide! I can give the screen more time to see if it improves at all, or maybe try going back in and trying to see it is trapped alcohol that can be released

Thanks for the guide. Battery replacement kits are now available on Amazon: https://www.amazon.com/Nintendo-HDH-001-... (they weren’t in November! I was also looking for this during that time)

Unfortunately, the battery was much harder to remove than I expected. I did use a lot of isopropyl alcohol, but the adhesive they use really was giving me a lot of trouble. I should’ve wisened up and googled other adhesive removal methods or tried a new approach other than prying with the spudgers.

Well, now the LCD now has what looks like pressure damage in the bottom left where I’d imagine a lot of the prying pressure went. It is much more noticeable when the screen goes all-white, and not too bad with darker colors.

I don’t blame iFixit for my mistake of course, and it is really disappointing that Nintendo used the amount of adhesive that they did. But I hope this comment can serve as a warning to others attempting this repair to be more gentle even if it’s refusing to come off.
