In the first five months after I'd got the KPA there was just one Power-on-Error of the KPA, the display says nothing, the KPA won't start. Therefore I learned to cut it off from power, wait 20 minutes before trying again and starting then the KPA successful.
In the next three months the rate of these Power-on-Errors rose slowly to "one time a week". Now, two additional months later I'm at >2 Power-on-Errors a week. And I ask myself: When will come the day it will always need start-wait-restart action to use it?
Anyone with similar problems?
Of course I turn the KPA correctly off each time, I tried also to shut it down only after several minutes running in tuner-mode before shutdown but it didn't change nothing. I am sure I didn't get a power-fail before downing the unit.
All in all that's way far from my expectations on a "1.500 € piece of equipment".
