AW9000 LED blinks white rapidly and irregular.

Hi,

I have two sets of AW9000 and recently both of them have stopped working, with the LED blinking white very fast and irregularly. The iOS app can't find the speakers.
I've tried to reset them by holding the Preset 1 button while powering up. The light blinks amber, turns solid, then blinks again and I release the button.
As I'm getting ready to set the speaker up, the light starts blinking white very fast and irregularly again and nothing works.
Neither of the speakers show up in the app, nor does the setup button work.

I've connected one of the speakers to the wireless router and it's just the same, the white light blinks rapidly and irregularly.

Any thoughts or solutions?

Thanks

It looks abnormal, you may just send them to service center although little bit heavy
