    I found the part, the number is SD8585S. It's a primary side regulator with a built-in MOSFET: http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20140702013249635399057724628288&c=AC-DC转换电路 The page lists a block diagram, but it doesn't appear there is an actual...

    That sounds like a good guess. In that case, it's probably the MOSFET for the switching converter. If all the pins are at the same potential on that chip, and the secondary side of the xfmr is dead, which do you think is more likely to have failed due to the sudden impact from a relatively...

I recently had a phone charger stop working after I dropped it off a balcony, so I've been probing around with the circuit to see what got disconnected...
