I had similar trouble related to the synthesizer boards on a K3. On the newer KSYN3A boards there is a green LED on the top edge of the board that should be ON if the board is working ok. You mentioned a sub RX so you should have two of these boards mounted against the back of the front panel.

Elecrafters, i'm on vacation at a /p qth and K3 #2878 has quit working. I have no power out. The display reads 0.0 watts when holding the tune button, regardless of mode. In RX I hear noise from the headphones , but no signals. The noise sounds like the K3 sounds when no antenna is attached.
