Hmm, what a bummer! Could very well be the polarization voltage oscillator or voltage multiplier circuit following that oscillator that are not working. That's the 14-pin IC and surrounding parts on the board. My first suspect was C20, for which R?de has used an SMT film cap that was notorious for cracking. But C20 is a through-hole (wired) part on this board. A next likely, and not uncommon issue, is a cracked SMT capacitor in said oscillator circuit. But those cracks are in most cases microscopic and only visible by cutting the part and watching under an electron microscope. If you have a multimeter and you're willing to spend some time on fault analysis,? I can guide you through the process. By doing this, you can at least exclude the capsule from being the cullprit.

Suppose you send in the mike to R?de for repair, I assume they will not do a repair at component level but simply do a board swap. Like others already mentioned, this is probably not economical. Ask for a quote before sending in the mike.

Good luck!
