Assistance Needed for Diatone Mamba F405 MK2 FC Stack Issue (Solid Green Light)

[rudranshsinghmahra]

I am experiencing an issue with my Diatone Mamba F405 MK2 FC stack. When connecting the stack to the battery, I only see a solid green light instead of the usual multiple lights. As a result, there is no power to VTX and Receiver. I’ve checked the stack with a multimeter for shorts but found none, I also tried replacing the JST-SH cable but the issue is still there. Can anyone please assist me in resolving this issue?

Not one person responded? Fabulous!!! I've got the same exact problem. Am going through the motions of upgrading to elrs(nightmare) and I just soldered on my new receiver and the same thing happened. Did you find a fix by chance?

Yeah, I have fixed it. The issue was with the connection of the capacitor the big one which is connected with the XT90 connector. Somehow it got loose and was no longer connected, I re-soldered it again and till now I have not faced any issues. In your case it might be due to this or may be not . I suggest to remove all the components that is rx, vtx or any other thing and then test it and then connect them one by one, while powering the stack.
