ive got 2mmmv3 today...but one of my unit dont want to power off,,,!!!!!

nothing to do...i remove the on-off switch and the controller still power on!!!!

but the green and yellow light blink...if i turn the esc switcn to on position the cotroller work flawlessly...really strange
and if ive removed the on-off switch...could it be ramming(if the word is exact..loll)for the esc??????
