    Hardware USB cable connected switch indicates charging but in fact is not

    If your talking about the choke on the D+ D- lines this should have continuity Just above the M92T36 is a dual P channel mosfet (6 pin) can you test what voltage you have on pin1 with the charger connected

    Hardware USB cable connected switch indicates charging but in fact is not

    Do you have the same voltages on pins 21/22/23 of M92T36 since you changed it What voltage do you have on pin 28 of M92T36 with the charger connected, can you test this pin for a short to ground aswell.

    Hardware USB cable connected switch indicates charging but in fact is not

    So both M92T36 had low voltage on the mosfet gate pin 21

    Hardware USB cable connected switch indicates charging but in fact is not

    I can't think of any thing else that could be causing this only that the M92T36 is faulty, did you have the same problem with the M92T36 that you removed?

    Hardware USB cable connected switch indicates charging but in fact is not

    Can you test voltage on the LDO pins 38,39, and 40 with the charger plugged in and test these for a short to ground.

    Hardware USB cable connected switch indicates charging but in fact is not

    Between the 2 mosfets above the usb port is a big cap and a small one can you test the big cap for a short to ground Also next to pin 21 of M92T36 is a resistor can you check the resistance of that

    Hardware USB cable connected switch indicates charging but in fact is not

    Can you test what voltage you have on pin 5 of M92T36 with the charger plugged in.

    Hardware USB cable connected switch indicates charging but in fact is not

    Try running your soldering iron over pins 21 22 23 to make sure you have good joints check to make sure you dont have continuity between pin 21-22 and pin 22-23

    Hardware USB cable connected switch indicates charging but in fact is not

    Thats where your issue is you should have about 20V on pin 21 and about 15V on pin 22, if you have changed the M92T36 check you dont have any solder bridges around these pins and check that they are soldered on well, can you check what resistance to ground you have on the 2 pins.

    Hardware USB cable connected switch indicates charging but in fact is not

    What voltage do you have on pin 22 and pin 21 of M92T36 still with the charger plugged in

    Hardware USB cable connected switch indicates charging but in fact is not

    What voltage do you get on pin 9 of M92T36 again with the charger connected

    Hardware USB cable connected switch indicates charging but in fact is not

    What voltage do you get on pin 1 of BQ24193 with the battery plugged in and the nintendo charger plugged in

    Hardware Switch V1 no USB data activity issue (everything else works - dock, charge, etc)

    If the usb controllers damaged you usually get low resistance to ground on the datalines.

    Hardware Switch V1 no USB data activity issue (everything else works - dock, charge, etc)

    If it works then its fine, sometimes with the fault you've had it damages the usb controller in the SOC.

    Hardware Switch V1 no USB data activity issue (everything else works - dock, charge, etc)

    The 6 pin IC is a ESD protection device texas instruments TPD2E1B06 or equivalent You can get away without using one but you obviously loose the protection the device offers. Have you tested what resistance to ground you get on the 2 datalines at the points on the topside of the common mode choke?

    Hardware Components used on the Switch (mostly the motherboard and main console)

    Maybe RSX101VA-30 or equivalent

    The one in the green box

    Hardware Switch V1 no USB data activity issue (everything else works - dock, charge, etc)

    Check that you have continunity from pins 6/7 (from Left) on the usb port to the top side of the common mode choke which is just to the left of the big cap above the usb port. All so check the usb data pins D+ D- 6/7 for a short to ground The PI3USB has nothing to do with the switch's usb data...

    Hardware Nitendo Switch Error 2101-0001 not charging

    Why are you testing pin's 5 and 6 for a short when power is applied to the board? Have you got a short to ground on pin 6 of the M92T36 if so and you have replaced that IC three times I would asume that the short is somewhere else on the 3V3 rail.

    Hardware Switch not turning on

    Yeah that’s where CC1 and CC2 end up at the M92T36 so if I where you I would just change that IC or you could test to see if these lines respond to the cable being inserted but it’s a bit of a faff

    I rather enjoy a life of taking it easy. I haven't reached that life yet though.

    That's a relief to hear. Do you know what happened?
  • SylverReZ @ SylverReZ:
    @BakerMan, Any idea what happened? I hope that your brother's doing good.
  • BakerMan @ BakerMan:
    Well, from what I've heard from my parents, he had a seizure last night, perhaps an epileptic episode, fucking died, had a near death experience, my dad called the paramedics, they showed up, took him to the hospital, and he woke up covered in tubes, and started complaining.
  • BakerMan @ BakerMan:
    He couldn't eat until after his MRI, when he had a bomb pop.
  • BakerMan @ BakerMan:
    What matters now is that he's doing alright.
  • Veho @ Veho:
    But you still don't know what it was?
  • Veho @ Veho:
    Has he had seizures before?
  • The Real Jdbye @ The Real Jdbye:
    apparently stress can cause seizures, my brother had one during a test once
  • The Real Jdbye @ The Real Jdbye:
    never had one before that, and never had one since
