    Hey guys,

    I have bought a faulty Switch which won't turn on. I put it on a USB meter and measure a charging current of 0.470 Amps - so far so good. But it won't go to fast charge and neither turning on or giving me a backligh - not even a change in the current. I changed already M92T36 but no difference at all. All caps around the chips are not shorted. Any clues? I am a bit helpless. ^^

    Edit: Nevermind: I found a lots of shorted caps behind the cpu side.... :-/

    Did you fix and get it going again? Did you figure out the cause?

    Maybe other shorts on the board? Not good solder connections by m92t36? Maybe not good m92t36? It can be everything. How much voltage do u get by m92t36 Pin 5 and Pin 6?
