Heh, on the way back from the avionics shop to get the IFR cert done and a
new VOR head installed, the LEDs went out on our #1 comm (KX-155). The first
2 digits ( 121.9, the 12 is gone). Just went out in flight. What is
involved in replacing the LEDs? Is it the whole cover?

If it's a KX-155, they are not LED's. I've heard that sometimes you can get them back
by cleaning the contacts and reseating the display board. I've got a couple of segments
out as well.
