Voyager SE problem with osc 2 & 3 after sitting unused.

Hi there! I've got a Moog Voyager Sig. Edition (cherry wood, thanks very much!) but I've got a problem:

Last summer, I had to go to the other side of the country to see my family and help out with flood damage and such. I left my Voyager at home, sitting on a keyboard stand (like the rest of my synths). I ended up having to be gone a LONG time, so the Moog stood unplayed for 6 months.

A few days ago (back at home), I powered up the Voyager, only to find no sound from Oscillators 2 & 3. I tried recalling some of my presets - still no osc 2&3. I put the Voyager in Panel mode, but still nothing. No signal when I turn their levels up in the Mixer section. Osc 1 works fine. Noise works fine, and Ext. In works fine. Just nothing from oscillators 2 & 3.

For some reason, I doubt that this is a mixer issue. I'm guessing that for some reason that control voltage isn't being received by those oscillators, so they are stuck at DC voltage (zero Hz.) I get a small "thump" when turning osc. 3 on, which seems to maybe support this.

Anybody else had this sort of problem? Yeah, in a perfect world, I'd never have to leave ANY instrument unplayed, but y'gotta take care of your family. Could it be dust (or something) in the multipin CV connector blocking voltage to those oscs? I don't have the Voltage Expander to check this theory out.

I'm out of ideas, and it seems like this is a solid enough piece of gear that merely sitting on a stand for a long time shouldn't damage it.

Thanks, all, for taking the time to read this, and maybe respond.

Troubleshooting:

Using Osc. 3 as a mod source behaves as if Osc. 3 is DC. In other words, if Mod Source is Osc 3 and Destination is Filter cutoff, turning up Amount results in filter decreasing to minimum.

Setting PGM mod source to Osc. 2 and Destination to Filter cutoff result in no change.

So... that's Osc 2 dead and Osc 3 stuck at DC? Anybody have any idea why?

Power surge damage from a near by lightning strike while you were gone?
Time to call MM and get an RMA to send her in.
