Backlight failure on those is really common.
Here’s a poll that was taken on the COPA forum a while ago:-
The basic 55 computer has an extremely dim display. This issue and adding roll steering are the significant differences when upgrading to a 55X
I have a Stec 55 (non X) installed
on my first recent night flight I noticed that the face is not illuminated – is this normal or just on may one not working?
thanks for the help
