Htmlkid Posted April 8, 2020 Report Share Posted April 8, 2020 My narco secondary navcom upon startup today did not display anything. I turned it off and on and nothing...in flight I turned it on again and it worked perfectly. This happened again after shutdown park and restart... any ideas what could be going on?

R Van Dyck Posted April 8, 2020 Report Share Posted April 8, 2020 I had the exact same thing last week. Get you a 7/64th Allen wrench and remove your radio from the tray and re-install it. Press firm in the corners to assure a good re-seating. Then tighten with the Allen wrench to allow the cam over and squeeze the radio tight in the tray. My problem was the Cam got partially cammed over and tightened, then you fly, and vibrations loosen up or the cam slips, and your radio loosens up the seating in the tray and then you loose it.

OR75 Posted April 9, 2020 Report Share Posted April 9, 2020 Thresholds can be different for different instruments older instruments Can have a narrower range 1 Quote Link to comment Share on other sites More sharing options...

Check power/grounds. If that makes it, could be bad display. Quote Link to comment Share on other sites More sharing options...
