V6 light is flickering while its unplugged

I've tried to unplug my V6 box and for some reason every time i turn the power switch off or unplug it from power, the power light turns orange and starts flickering even though its not plugged in. The box is also making a sound and the only way i can get this to stop is by plugging it into power again otherwise it will keep flickering. What can i do to fix this. The box works fine otherwise.
