Seeing if anyone else has ran across this before. We have 2 430's in our 182, I was out flying last week and both screens starting turning white (color fading out) and then I lost the ability to transmit out and communicate any intentions. I could still here others over the radios but I could not communicate at all. My guess is they were overheating. Anyone else experience this and if so have you looked into how to avoid them overheating? Thanks!
