Good afternoon. Help with a problem in Siyi ZR10
When you first turned on the stabilization and control did not work.
The zoom and the camera module itself worked.
Updated stabilization firmware via SIYI Assistant.
When updating the firmware of the camera module, the power was turned off, the microSD was inserted, the power was turned on, and any reaction to the power disappeared.
The USB cable was connected at the same time. The camera has stopped turning on. Power 4S.
I disassembled and measured the control points 1V / 1V5 / 1V8 / 3V3 / 5V / 9V, there was no voltage.
Power supply chip failed, 9V short to ground.
We unsoldered the microcircuit, applied the power to the 9V camera and ZOOM worked.
Stabilization as before etogo does not work. The stabilization firmware update did not help.
The gimbal motors are in hold.
I think the problem is in this chip. Can you tell me what microchip this is?
