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.

I need to visit Switzerland.

If I can't get it working I will come back to you. However, many thanks for your offer.

After removal of the back cover of the vertical arm it works. I think there is something mechanical with the contacts.
Now I'm going to try tapping on some “points of interest” to see what happened. It looks a bit temporary.... but it's leveling out.


I also reacts on my tools, tilt, pan - all OK. No calibration needed.

If I put all together as it should be and it will not work again, I will cry...

I had the same problem, went through 98% Gimbal calibration but kept looking down (video working) would not level and hung at that point in the calibration.

I had to slide the camera out several times to be sure the contacts were seated and then it magically started working again. Not sure if one side of the rail wasn't actually seated or what.

My problem comes and goes. The Power supply is stable (no contact problem at the camera mount) but the gimbal initializes (one beep and the success melody when it levels) or even not, no beep, no reaction, camera still powered and working.

Hello! If you don't touch anything and don't change the observation and test conditions yourself, then probably this strange(!) behavior of the camera depends on the mechanical movements it makes.

I would bet on tape connections undergoing torsional and sliding movements, for example, during camera initialization. In particular, the two ribbon cables passing through the Motor Roll and connected to the MB of the gimbal.

And what are the results of the software test?
