I have a new Zenith Mk3. It connected perfectly and has been streaming via Innuos Sense for days. Finally, I decided to rip a CD. I put it in the slot, it took and began ripping. Suddenly, in the middle of the process, it quit. The unit turned itesel off (no light). The iPad I was using lost connection. I pressed the front button on the unit, it turned white and ran through the cycle but, instead of turning blue, turns itself off. Now I have a CD inside the unit but cannot get it to connect (turn blue). When I turn it off and on the back toggle switch, it just cycles in white and then turns off again. Now the kicker: this is the second unit I have had that has done this. I bought a Zenith Mk3 in Sept. and it did the same. I eventually shipped it back to the factory and they replaced it with this one. I'm at a loss...
