I got a Lea about a week ago, and have only used it for perhaps 6 hours of run time. Since I typically don't like using a passthrough, I hadn't tried that until last night, and then only briefly. Seemed to work fine. But now, I can't even turn the thing on. Suspecting that maybe it just needed to be charged, I hooked it up to the A/C charger. Instead of doing the three blinky thang, it gives me an angry, rapid-fire, smallish red blinks - nonstop - at which point I unplug it. Anyone seen this happen? I didn't experience what you demonstrated in the video.
