Power button malfunctioning, sometimes needs hard presses.

I left my N3DSXL in storage for a couple months, and recently took it out to bum around Luma a bit. Powering it on used to be a cinch, but now it takes a good long fingernail press at weird angles for the button to pick anything up. Attempting to press it now results in nothing, not even plugged in. I'm assuming it's a micro switch, and considering the thing's used, it's probably worn out/kapoot (like the X button).

I'm seeing a step-by-step for the old 3DSXL's power button, but nothing for the N3DSXL. Anything on repair/replacement? Wouldn't look forward to soldering (no equipment, expertise, general sanity), nor could I trust any of the low-rated repair places in my area to do a good enough job that would make the 50-200$ easier to swallow...

But if it's been done, I'm all ears.

Also– mail-in shops that have done really good work on consoles based on customer feedback would be great. I'd post this on Reddit, but the more I go there, the less help anyone is, especially with the new-er corporate corpse era running it's course.
