Is this contact too damaged?

i'm taking apart a 3ds that looked absolutlely destroyed, despite this both screens worked (and yet they were all yellow and gunked up from an unidentified liquid, i'm guessing cola of some kind.) and every button worked, apart from the A button. So i removed the sticker, cleaned the contacts and at the moment they look like this. is this too damaged? should i not bother buying a new button dome sticker?

the contact won't clean more than this, at least not with isopropyl and q tips.

please let me know. i'm an amateur and i don't know if this is still salvageable, thanks in advance!

Hi Enerd!

First things first! Regarding the first picture, on the left side there is corrosion as well! Please clean the whole motherboard with isopropyl alcohol.

Regarding the 2nd picture, you already did a lot to clean it. My guess is that a new button sticker will work and I would try this first. If not, you can remove the (new) button sticker and remove the rest of the dirt with a tiny flathead screw driver (be REALLY careful with this!!! Do not touch the traces, as they can be cut easily!). And after you cleaned it with the flathead, then use isopropyl alcohol again to clean it. Then after this, place (again) the new sticker button on it and test again.

I would definitely buy the new sticker button (2 of them just to be sure) to try. A new motherboard is rare to find and if you can find one, it's probably pretty expensive. Sticker buttons are pretty cheap and worth a try!!

I wish you good luck and let us know how it goes!
