Hello there, thank you for reaching out and I am sorry to read and to know that you've encountered this kind of issue on your DJI Phantom 4 Advanced remote controller. For us to be able to assist you further, may I know if you tried to power on the remote using this sequence? Press once release and then press and hold the power button? In other words, the sequence can also be double-pressing the power button but the 2nd press should be press and hold. If in case the issue still persists, please take a video showing the response of the remote. Thank you.

I tried both the type of sequence
And when i connected charger to remote not charging leds are blinking remote released some sound.
