Fault mode after big electrostatic discharges.
#1
Dears,
My station stopped receiving discharges. It is "Station 2927, BLUE, FW 9.4, PCB 19.5/H1/E1"
'Fault' LED is continuously on, I believe because of 'Fault' mode.. because of overload/interference?
Everything began on a day, when there were big electrostatic discharges in air.
Radar's antennas collected static, and presumably, burnt something on PCB.
Radar was connected to Internet via unmanaged switch over ethernet cable, which has been burnt that night - had to be replaced.
Static was so powerful, that I heard 'clicks' in the middle of the night from another room. I walked into the room where radar was located and saw sparks near antenna connector. I had to use insulated pliers to unscrew F-connector.
Good news: built-in GPS module works, network adapter works.
With disconnected antennas, from debug log:

I did open receiver and visually inspected with a loupe, there is no visible damage.
I belive, that static damaged something, but my knowledge is limited to design/construction.

Anybody has similar issues?
Where to troubleshoot?
Any help is appreciated.
