No LED on Eagle Tree Guardian

Has anyone had this problem? Updated to version 1.7 and LED working when connected to the computer but not now it,s installed in the plane. It operates the control surfaces while on the bench but am reluctant to fly it if there is a problem.
Any help appreciated.

Hi, if the LED is not doing anything, this normally indicates that the unit is in "NO STABILIZATION" mode. This will happen if a 3 position switch is controlling the mode of the unit, and the switch is in the middle position. Does this explain it?

Thanks for your reply.It is controlled by a 3 position switch with centre position disabled but there is no LED in any switch position.

Hmm. We know the LED is physically working since it blinks correctly when plugged into USB. To confirm, is the behavior you are seeing different when the switch is moved to different positions (i.e., is it stabilizing 2D in one position, 3D in another, etc.)? If not, I am wondering whether the receiver channel is not correctly mapped to the switch, or if the mode switch cable has failed?

Disconnected & Reconnected the unit and it is now working as it should (hopefully).
Will fly it in the day or so.
Many thanks,
