Is there a way to revive a dead LED?
While testing an LED I bought, I may have given it a bit too much power, and it burned out. I can't get it to work with any power source. I could buy a new one, but I had to mail order it from The Electronic Goldmine, meaning I would have to come up with about eight bucks worth of stuff I don't need. Is there a way to bring an LED back to life?
Nope. If its dead, its dead. You don't say what kind of LED it is but, if you look around you can find a bunch of 'em for way less than $8.

It's not pinin, its passed on! This component is no more! It has ceased to be! It's expired and gone to meet its maker! Its a stiff! Bereft of life, it rests in peace! If you hadn't soldered it to the board it'd be pushing up the daisies! Its conductive properties are now history! It's off the twig! It's kicked the bucket, it's shuffled off this mortal coil, run down the curtain and joined the bleedin' choir invisible!! THIS IS AN EX-LED!!

Luckily, I only paid about $2 for the LED. I was saying I would need to get $8 of stuff that I didn't need just to get the LED.

If its just a bright white LED you need, go to a dollar store and buy one of those key chain flashlights and take it apart. You get the LED, a couple of button cell batteries, and a split ring key ring for $1 or $2.

+1. (ie, "yep").
Semiconductors don't recover from being cooked. Get another. As Burf says, there are certainly cheaper sources unless there's something specific/odd about this one.
