    Hey guys,

    I've got a faulty Switch from ebay, with a broken USB Port.
    I tested the Switch with a fully charged battery, but it could'nt bring it back to life, there is no power.
    I thought maybe it's a short at the port, so I soldered it out and cleaned the whole board, but still no luck. I tested every part in an other Switch, everything works except the mainboard.
    Maybe some of you faced a similar problem or have an idea which part on the mainboard is faulty.

    Regards

    Unless you have a voltage meter and have documented pinouts of the board with the expected voltage of each lane/chip your probably never gonna found out what part of the board is blown or corroded

    True. Unfortunately I can't find any documentations or schematics.

    Tried connecting it to PC? Not stuck in RCM is it?

    If not, then your first port of call is to check the M92T36 to see if the 3v rail is alive. Check for 3v on pin 6
