E90 gimbal dead

[h-elsner]

I have a repaired E90 camera that will not level, no reaction from gimbal at all, no beeps.
The camera itself is bound to the controller and shows video. So, power supply on gimbal main board works. It powers camera and WiFi board.
Any ideas?

The front LED of the camera goes through initialization process and stops with blinking yellow forever.

Have you tried a gimbal reset?


Do you have another e90, C23 or L1 available you could swap gimbal boards if needed?

The L1 and e90 are pretty much the same hardware. How similar is the e90 behavior to the L1 discussed in this thread?

Yes it sounds like that L1 behavior. Reset doesn't help. On the serial connection there is also no reaction.

With SD card in the front LED blinks green and goes to solid green if connected to ST16. Looks like the camera itself (at least the LED codes) known nothing about the gimbal. Still no sign of life from gimbal.

I think the most likely thing is a deep firmware problem with the gimbal board. Or it is just damaged. It would be good to know if the camera will at least respond to a replacement gimbal board.
