Question about Sennheiser MD421-II Professional Microphone
If it's dead, a connection is already broken inside.
Much more unlikely is that the capsule is at fault - and if it is you can't make things any worse anyway.
Who cares if you break a connection when you take it apart - as long as you can use a soldering iron, it's easy enough to fix. If you can't, why would you be taking apart in the first place ;)
You'd be mad to send it to Sennheiser to solder 1 or 2 points then send it back to you! Waste of time and money.
Try learning something yourself, especially if it only cost $10 and doesn't work to begin with.
Remove the capsule assembly - desolder and disconnect the wires at the base of the mic (not from the capsule) yourself (see, opposite of last advice), then connect them directly to a cable with an XLR on the other end. Forget about ground for now.
Now plug it in...do you hear anything? If not, get a multimeter and check continuity between capsule and your XLR. If you have continuity, throw the mic out. If not, replace those wires. Still nothing - chuck it out.
If you are hearing something (it should sound absolutely fine, clear, loud etc), ...find the broken connection elsewhere...but also, be happy because it definately still works and is definately fixable and you can do it yourself.

A microphone such as the MD421 does sound too good to be true for $10!
I would strongly suggest you do not try to take it apart as the connections inside will be destroyed. I know people that have had a go at taking it apart & destroyed their mics, ended up sending them back to Senheiser & having to pay more to get the extra damage fixed. It really is a false economy.
