Hi folks, can someone help me to identify the component in the pic with the 100 on it? As you can see from the pic, the component on the left is fine but the one on the right is damaged and needs to be replaced. Is this a difficult repair? I have some soldering experience but haven't repaired one of these before. Thanks.

should be very simple for a novice, as there's nothing in the way save for the Solid state cap. just desolder the leads from the under side of the mobo, replacing the damaged item with one of the same. easy peasy

thanks for the reply. There's actually no leads on the underside of the board for this component, it just seems to be soldered on the surface of the board. Do you know what the component is called?

I think its an inductor but there are no identifying markings apart from the '100'.

it is an inductor, but id have no idea where you would acquire a replacement a side from China. it appears the wire is soldered to the metal clasps...so you would have to
desolder it there and resolder it on the clasp...which doesn't look easy peasy anymore.

I actually found a local place that sells them. Did a bit a googling and found out that the 100 means it is a 10uH rated inductor but I'm still not sure how to find out any other ratings such as current etc. I'll probably drop into the shop and ask the sales guys in there. Thanks for the help.

don't worry about current & voltage as long as replacement is similar in style. that is a surface mounted component which is soldered to top side of board not a thru hole component that is soldered on bottom side of board. will have to use a soldering iron to remove the 2 silver pads of the component carefully 1 at a time then place new component in it's place & solder it. there is no orientation\polarization required.
