Hi all,

Just cracked open this Samlex inverter to see why the power input light comes on, but no juice comes out.

Owner said it got wet, but I didn't want to believe that a Samlex would be killed by H2O. Now that I'm looking at it, it seems it got very wet. A lot. There looks like there's plenty of water damage all over the board.

While inspecting I came across this component, noticeable because of all the rust-colored excretion around it. I'm wondering if anyone knows what the component is, just for my own education. It looks like a tiny transistor to me...?

Attachment not found.

Looking forward to your thoughts.

    Hi Casey,

    That part looks like a Surface-Mount Capacitor. The adjoining part that is not stuffed is labeled C ??, would bet that the white Legend labels the part in question as C-something.

    Would bet that the residue is not rust. FWIW. Good Luck, Vic
