When I engage AP during the flight the system starts setting something.

What can be the reason. It worked propoerly a few years but last year the display lost some dots and I sent it to factory.
The displey was exchanged now the problem as presented on this movie.

Very apreciate all sugestion what can be the reason.

BR,
Witek

It appears as though the unit is attempting to enter the temperature calibration routine. Where did the unit get repaired? has anything changed on the RS-232 connection/wiring to the unit?

Trutrak problem

The unit was sent and repaired in Trutrak (Bendix).

I'm assuming that means MidContinent. Sounds like there may be an issue with one of the boards. I would suggest giving them a call and explaining that they just repaired it and the issue you are having.

Repair

Yes, it was done in MidConyinent, Wichita,
Do you suggest to send it back? I already checked all R/S connections and seems all is OK but still the same problem.

Best regards,
Witold
