EZOSD not working... what could be wrong?

Hey guys,

I just got the EzOSD, after trying it and getting it to work, it seemed to have stopped wanting to do anything. I haven't even had one flight with it

Something strange happens... when I connect the battery the FC (Naza) turns on but the ezosd and the 5.8 GHz transmitter don't have any signs of life (no leds).

Does anyone have any suggestions?

Thanks!

Check the current sensor of the EzOSD. I think there is a fuseable printline broken. Happened to me also ( had ground problem). The circuit is getting his power from the current sensor pads and from there a tiny printline is going to the rest of the circuit. This one is broken.
You can measure this with Multi meter (resistance). If this one is broken (acting as fuse) you can simple solder small wire over this print line. It will work as new.
