hmmm how do i test that ? do i need to test all those points ? continuity against ground ?
Test for continuity from one side to the other of the choke

Sorry for the late reply been kinda busy these days. Hmmm let me see if i understand this correctly. So all same number chokes should have continuity, and they are not suppose to have continuity to other chokes with different numbers (e.g.choke 1 continuity to choke 1). Pintglass was wondering if your's had docking issues? seems to me that we have the same issues from the broken charge port to a shorted P13USB. I haven't tested the switch with the dock.
Have you not got a dock to test it in, it may work as it is.
I don't have a dock, il try to borrow one and test it out. I will update soon as i tested it.
Was i correct on how to check continuity with the common chokes?
2) I could not find any capacitors that are shorted near M92T36, BQ24193 or P13USB. I could only find some shorted capacitors. I've marked them on the attached photo.
There not capacitors they are inductor's
Have you tried to connect the switch to a pc after you've inserted the charger, does the pc recognise it.
Measuring across Cluster B 6 and 4 gives me -4.0V. Measuring across 6 and 5 I get -4.5V. Not sure why I get negative voltages (black probe is on 6 which is ground).
Guys,
I have a switch that will boot hektate only, it also doesn't seem to want to fast charge.
When I plug in the charger I get nothing on the screen, no power indication.
I tested the continuity across the caps by the M92T36, BQ24193 and P13USB, no issues.
Because the last unit I repaired had a P13USB issue, I just went ahead and replaced it as I had ordered 2.
I pulled the board out and plugged in a battery and a USB-C through a USB tester. I get .48 amps at 5volts being pulled.
Because everything checked out good and I was stumped I tossed it into RCM mode and was able to boot to hektate!
It came up and the screen works, everything looks good.
No clue what this is now, is it a hardware problem or a firmware issue?
Thanks!

Do you get the same readings on the pins of m92T36, are the readings with a charger plugged in.
Are you sure you've not got a short on the 3v3 rail
Inductors can make that sound, Video chip can go bad common situation with non original docks. Does it load hekate?
I do get the same readings. The readings are with a charger and no battery connected. I don't have a short in the 3.3V rail!
Check chokes right before Video Chip, you should be able to read continuity on each line.
Are you using an original nintendo charger, check to see if you have a short on the usb D+ and D- lines
Yes. Only original charger and official cable (from Pro Con) when connecting to PC. No short there. I also plugged the cable and confirmed continuity from the male end (USB A) to the board test pads
Check that you've got continuity on the choke just above the usb port on the D+ D- lines, if you've tested for continuity up to the usb test points under the audio chip then its fine.
