    Need your advice, switch not powering on. Now APU Heating rapidly after removing sx core ribbon with battery connected and pressing the power buttonmakes the APU heatup so fast. tested components using multimeter around M9, BQ, P13 no shorted capacitors..
    Sx core installed.blinking blue light..then solid green. but no sx logo. doesnt show boot.dat eror even sd card removed.
    i'm assuming something is shorted.. thats why apu is heating up so quickly.

    switch unit is version 2
    m9 - pin 5 3.3v
    pin 6- 3.3v
    getting about 4v on caps around BQ IC
    no shorted caps around P13usb

    any help suggestion to figure out whats causing the issue.. i swear..i just removed the sx ribbon cable to test if it still boots up normally or the capacitor is cusing the issue.
    TIA:cry:
