KX-155 LEDs

One of my co-owners flew the plane a couple days after the digits vanished
on me. He said it worked fine. Hmmm.
I was very cold on my flight. Enough that I could see my breath. I wonder if
that had something to do with it.

Aaron,

I hate to press to much but I really need the help. How exactly do you
remove the displays?

Thanks very, very much

John, Cory, try this:
Take the displays out. Burnish the silver contacts on the displays.
I used a pencil eraser. Note that the contacts are not gold, if they
were they would not tarnish. Put a bead of dielectric grease on the
display's contacts. This will create a gas-tight contact, and keep
the condensation from bleeding off the +150V used to light the
displays. Put the displays back in.

This is what Conrad up at the Radio Shop at KORH did to my KX155's
when I was having similar difficulties a few years ago. No further
problems.
