My primary is a TKM MX-170B which has performed flawlessly for years. During taxi after run up, I noticed the coms get silent (like dead air) and then slowly come back (almost like the volume turned off, then slowly back up). So, I taxi around a little longer and then the screen goes nuts, both screens scrambled and changing constantly. No operational comm, static and some odd radio traffic.

Back to the hanger, tried re-seating and resetting with no luck. Has anyone seen this before, or have a suggestion on TKM repair?
