I keep getting this "An error has occurred.Press and hold the POWER Button to turn the system off" error. All I have done is shutting down the system by holding the power button and now 10 hours later when I want to boot it up again I get this error. I tried googling, but since I haven't actually done anything other than shutting it down, I can't find exactly what I'm looking for. I can still get into the gateway menu, but I keep getting the error once I try entering gateway mode. My version is 3.4. When I do the diagnostic test, everything says 'fail'. Help please?
