[amsat-bb] Elevation meter Rotor YAESU G-5500 stopped working

Hi all,

All of a sudden the elevation meter stopped working of my Yaesu G-5500 rotor controller unit .

No issue with the AZ meter. Rotor itself keeps on steering / working without any problem in EL &AZ (via interface EA4TX ARS-USB) so all still working fine (fortunately !) for satellite work.

Looks like a component failure in the controller unit or the meter itself ?

A physical check (opening the controller unit) didn't show any anomaly. Being a not too tech ham was wondering if any of you Yaesu rotor users had seen this problem before / around ?

Possibly anyone to hint/ indicate at a quick check in the schematic wire diagram to where to start looking for this failure ?

Thanks beforehand for yr appreciated advice
