    xbox one-s

    anybody got any usefull info on these?
    resistance readings for example - to find shorts in the vrm etc.

    Nope, not me. But given the hardware... particularly the GPU - an AMD HD7770 variant, I'd expect the GPU VRM and RAM VRM sections to read similar resistance to a discreet HD7770 GPU. Just a guess, though.

      solved now, m$ using tiny smd fets that regularly go shorted.
      typical m$ shit - they cant do anything properly.

        Interesting.
        Hey, I see more potential work (and customers) then!
        Plus, I'd much rather be replacing MOSFETs than doing BGA work with the old Xbox 360's... which would always come back (or get thrown away) at one point or another due to the silly GPU chip going bad again and again and again.

          the 360 fix is simple,
          put a spare cpu heatsink on the gpu and lose the dvd drive.
          obviously you hack it first to boot all games from a harddrive.

          in theory you could re-direct a lof of airflow over the original sink - but your still pushing your luck.

                  no, but as it's in bits while i find a fet that DOES NOT come in 25's, i can take a couple.

                      it's in another thread,
                      some unobtanium from the bitches at ON-Semi.
                      tiny little package about 3.5mm square.

                          Yeah, I've had that idea for a long time now, but never tried it. Should work fine, obviously, as the CPU heatsink is a lot better equipped to handle the heat the GPU produces than the stock (v1 or v2) GPU HS.

                          Of course, most people (if doing this for customers) probably wouldn't appreciate the looks of a "hack" like that, even if it will solve the problem for good.

                          Nah. Those can barely keep a 35W chip under 60C with good airflow, let a lone the Xbox 360 GPU, which I think is more along the lines of 50-80W, depending on how old/new it is.

                          Would be nice to find that one and link it here. I think I saw it a few weeks ago, but don't remember if I wrote anything in there or not, so may not be able to find it easily.

                              Hey all, I have an xbox one s that is shutting itself off right after I turn it on. Fan does not turn and so seems like a short. I have replaced all the mosfets that everyone talks about but still having the same issue. Since I cannot find a schematic I am lost on what to try next. Can anyone point me in a direction from here? I don't know what is connected to what and what values should be. Much appreciated!

                                put a meter or scope on the power supply connector and make sure the power is not dipping - those can cause problems

                                  Check the tensions and sub-sources, it may be some short
