    A1706 No display or cpu activity

    820-00239-09 motherboard. Draws 520ma then drops to 420ma. Black screen. Battery disconnected.

    Had a small bit of spillage around U3100

    PPVCC_CPU_PH1 and PPVCC_CPU_PH1 are 1.08v

    PPVCCEDRAM_S0_Cpu is 0v
    PPVCCGT_S0_CPU = 0v

    All the rest of the S0 voltages seem to be present.

    No display no chime/USb activity.

    Any ideas?
    What should the consumption be?

      Xbox One Controller - Phantom stick activity (sticks completely uninstalled)
      by Aimbit
      Hi All,

      I bought some used Xbox one controllers "as is/untested" and they both have the same issue. The joysticks go wild for no reason while plugged in.

      https://youtube.com/shorts/YTYtjUPkBX0?feature=share

      I removed both joysticks assuming it was an issue with the sticks, but the video posted here is the activity of the sticks with no sticks installed! My only guess is one of the tiny IC's that reads the inputs is broken. There are two small ones near either joystick, and then one larger one. I found a replacement on Aliexpress for the larger one...
