Need help with repair of Logitech Z-680 speaker system

[bigsarge31]

I was replacing the fuses since 3 of the 5 channels were not work and I hit a small cylindrical part with small thin wire coming out both ends. One wire broke from inside the component and can't be fixed.

I would appreciate any help so I can repair it myself. Here is a picture with the part circled in red. I can take a better picture if needed.


Thanks,

Kevin

you must unsolder the coil (ferit core with rounded wier),be carefule this is double layer board (pcb),find the side of the boar where is attached (soldered),use a vacum pump if you have it or buy it its cheap.Stripe a wier from coil and find a similar from old power cord, atemmpt to find a same diameter of wier if it posible,Cut a new wier at the same leigt as old one.The number of circle on ferit core is very important,Apply the exactly the same number rounded on ferite core and throu it .
you may dismout old RCA cable to find proper wier diameter (litz cble).
The ferit core with wiere preventing a booming sound to speaker on system power on/of.
sory for my bad engl.

you may also dismount a broken one ,strach a broken wiere and attach a booth side with solderring (not to much thinol on soldering point),asebly a coli an dput it back.
On the wier is a thin layer of isolation (like plastic layer) gently schrach a top of the solderin point to obtain beter soldering contact.at the end you mus isolated whole wier from ferit core (no contact betwene wiere and ferite) use nail paint(i dont know right word for that) or by a plastic spray in radio shack store (it is better for all electronic work you must have it for..)

Sorry for the late reply. I will work on this tomorrow and see what I can do.

Thanks for the suggestion.
