The wires are not connected, need to reconnect
I opened the microphone and discovered that the wires have been broken from where they are soldered. Need to make the wires longer and replace. How ?
It wouldn't cost you that much. You can acquire some solder, flux (that will help things go much smoother), wire and a soldering iron, for quite cheap. Even the desoldering shouldn't be too complicated.
Here's a video
I'll give you a list, from iFixit, or you can scour eBay and find the same things
This is "non-leaded" solder, that's the good stuff
Make sure to "tin" the areas and wires, prior to installing the new wires. You'll want to add a dash of flux, then add some solder to the wires, then solder the wires to the board
