F1 and F2 have continuity
Kind of at a loss
Any way I can check the other components? I don't want to start replacing stuff if it isn't the problem.
Other than the charging adapter, battery, charger port, and micro-fuses, you're left to contend with are the power supply filter and IC charging chip.
Because information for the (o/n)(2/3)DS(XL/LL) is scarce for the [power supply filter / electromagnetic filter / common mode choke], we have to refer to the Nintendo DS(i) (XL/lite) under the assumption that their shared AC charger standard and similiar layout around the charger port means this component should be compatible.
The power supply filter for the DS(i) has the informal part number
EM10.
These are the specifications found about this part:

Late Edit #2 - Ignore above measurements. Check with ruler as the real size is roughly 3mm x 2.5 mm when using this image. There's probably a +1 mm tolerance.
SKU: 2109600
Code: NDSLR 2347
Searching
eBay, Amazon, and aliexpress turned up empty as this part has long been discontinued. Also searching at
digikey and
mouser for similar spec'd chocks didn't yield any results.
* The only known e-store that still stocks this is:
Late Edit #1 - Found two addition sources.
* [ADDENDUM] - The closest matching common mode choke that I found is made by Pulse Electronics with part number
PE-1210CCMC601STS. The footprint, impedance @ frequency, and max current rating are exact to
EM10, but where it differs is that its max DC resistance is 120 mOhm. Whether or not being short of 80 mOhm is acceptable is unknown.
However, both iFixit and Retro Video Game Repair states the power supply filter is a concern when you don't see the LED charging indicator light up. That means you can rule this one out, which leaves the IC charging chip.
The part number for this chip made by Texas Instruments is
BQ24072. Here's a quick search from digikey:
As for which exact option you should choose of the several listed there, I don't believe there's a wrong pick if they all have the same specs. The additional trailing tags in the part number probably refer to slight revisions, production batches, and packaging.

If the thought of workstation reflow (heat gun) and soldering does not appeal to you, there's replacing the motherboard for $20-$30 depending whether you buy it from China or US. You will have to account for the additional WiFi module and antenna. See the explanation in the next break below.

I noticed the motherboard you have is a revised model as there's a difference around this area. Yours is mostly like from a newer o2DS that has the WiFi chip integrated into the board.
