You have tested everything trying to determine why your home theater suddenly has no sound. One of the first things to check is your audio cables, which wear and break over time. Rather than shelling out for new cables, you can repair the old connection and brag about your new custom interconnects.
Instructions
1. Use wire cutters to snip the cables a few inches from the plug. Remove any casing to expose the soldering of the jack and write down where the wires connect to the posts.
2. Strip an inch of casing from the end of the wire to expose the strands. Twist them tight and look for discoloration on the wire that signal oxidation. If signs of oxidation are present, continue stripping the wire until you find good metal. Slide on your shrink tube now if desired.
3. Remove the old connections from the jack and clean them with steel wool to remove as much of the old solder as possible. Run a bead of resin core solder onto each post where you'll make the new connection.
4. Untwist the wire ends and fan them out slightly being careful not to break any. Strip additional wire or trim as necessary to fit the post properly.
5. Place the trimmed wire against the solder bead and reheat the solder as you work the wire in carefully. Place another drop of resin core solder on top of the wire if needed. Repeat until all wires are connected.
6. Cover the connection with shrink tubing and use a match to constrict the tube. Place the cable back into your system and ensure it is now passing the signal properly.
