URGENT!! CGO 3 Gimbal Not Working

[9design]

Hello Friends.


Having a problem with my CGo3 gimbal camera working fine recording tx wifi ok
But gimbal is not
No lights on gimbal board No sound/beeps no movement etc.

i have found a picture on this YuneecPilots forum in which a friend of us diagnosed a problem with an IC



But i cannot find this IC on internet because this given name number on IC can not be found any where

Can any 1 tell me its name/number

thanks.

I too had issues trying to find a chip for these boards. I can tell you the older GoPro (gb203 I think) gimbals have the exact same board in them and if you can get your hands on one you would have the part you need. I have several lying around I will see if any of them have a number on it.
Did you check the contacts on the gimbal and drone? These contacts tend to stick at times.

Did you check the PWM transistor on the Q500 Main board as shown in Attachment 55 of the WTFDproject document?

I think it is fine actually don't have much time to supply power to PCB because the both IC's in red circle are getting really hot any suggestions why they are getting so hot??
