The controller only flashes on one white light and wont charge any ideas what i can do

this happens when you are charging?

Put then it goes off should you have the controller turned on when charging

Hi sir, just to verify, did you attempt a firmware update before the white light flashing? Could you please tell me the drone you are using, and if it is possible, please also provide me with a short video first so I can provide you with the relevant solution for you to try. Thank you so much.

I've got the controller taking charge but it won't go past 2 leds
