Hi, I have recently purchased a second hand V3 hub. Previous owner claims the unit died after having connected a 10V supply instead of a 5V supply, and I intend to repair it. But it didn’t seem as obvious as I had hoped. So far I have only opened the enclosure to look at the circuit board.
This should be a simple fix with a soldering iron I imagine, but can anyone point out which are the capacitor and diodes that are likely blown? Will update the post later today with images of the circuitboard.
Update: I have reviewed the similar post for V2 hub, but the circuit is totally different on V3 and not comparable.
