Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I suggest first of all, that you should unplug the system, and leave it that way for about 1 hour or longer, unplugged from the power.
Then try it again.
If the failure is still evident, please describe exactly what happens - in point of visible electronic indicators, such as lights - when the power is turned On again. I might get a clue as to what the problem is, from that. Let me know about this, if it still isn't working, please. Thanks.
