It starts but quickly stops and eventually locks up with a window showing "Waiting on Hardware Initialization (Y,K,YTS)"
The second day I had mine, it did the same think. I was running on the battery, which turned out not to be a good one. It than took to using the "internal" battery (which will keep it up for about 2 min while you switch) and killed that one too.
So, when I got the power to the Maestro, the internal battery had to get re-charged, before the message would go away.
I believe I left it plugged in and off (charging the internal) for about 30-40 min and then all was fine.
Give that a try and hopefully it recovers. 73
I am using the Flex supplied wallwart but didn't have power on it long enough perhaps. I will let it soak for an hour or so and try again.
The unit was sitting on the self for a couple of months so something may have discharged internally.
When it happened to me, I took the cell phone battery out, plugged in the wallwart and did not power up the unit. After "soaking" for awhile, I powered up and all was well. Scared the C...* out of me!
If after an hour or so, this doesn't work, yea, I'd start a trouble ticket. But, do let us know how this works out.
