A few days ago my ZP90 failed to show up in the app. The white status light was no longer showing. There was however some power getting through, because the lights above each of the USB ports were flickering.
I tried using a different power lead, plugged into a different power outlet. This made no difference. I tried a factory reset on three separate occasions. Again, nothing.
Prior to this, there was nothing to suggest a problem, nor any maltreatment of any kind.
I guess it has just quietly died. Just as a last hope, does anyone have any other suggestions, please?
