    Xbox One controller 🎮 no power

    It won't power on, only blinks twice and turns off when on battery.
    The area marked red ia getting immediately hot when I connect the board to micro USB charger. I thought it might be the capacitor on C6 so I removed it, but looks not. I think the D23 is the first part which gets hot. What should I try? I'm a noob, have mercy

    Thanks

    U1 looks like it been toasty before. It may have shorted. Do you have a DMM you can use for tests?

    BTW, don't use unicode "emojis" in titles please. Some of us use old machines that choke on it.
    Things I've fixed: anything from semis to crappy Chinese $2 radios, and now an IoT Dildo....

    Excuse me while i do something dangerous


    You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.

    Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

      Dmm, digital multimeter? Yes, i do have it.
      Sorry about the emojis.
      Can you give me more details on what to test exactly, please.
      Thanks

        i doubt that will work unless you remove the chip, clean the pads and re-solder it - even if it's not dead.
        the soldering on it is cooked.

          Darn, it's really tiny 😕
          Could it be the diode or the tiny capacitor, so I check them before U1, coz it's gonna be really difficult for me 😅
          Should i use hot air or can soldering iron do the job, for the removing process?

            U1 is a 5v to 3v converter. The capacitor is 100uf 10v and for the diode I've used 1N4148.
            There's a thread here where they test U1. https://www.acidmods.com/forum/index...opic=43204.120

            Have you tested the diode with your multimeter ?

                The voltage on U1 is as follows :

                Pin 1- 0v
                Pin 2- 0.67v
                Pin 3- 0.36v
                Pin 4- 0v
                Pin 5- 0.36v
                Pin 6- 0v
                Pin 7- 0.08v
                Pin 8- 1.08v

                I saw what the right voltage looks like in the forum posted by diif (thanks for doing it so), this one definitely doesn't look right

                Checked the diode with continuity without taking it out, looks normal. Shows 1,when reversing shows about 220.

                Assuming that the U1 is faulty, which voltage should I have on U2 and U3 after removing U1.

                  Removed U1, the controller works now.
