This Sunday, I was playing and my FH suddenly died. No sound, no lights, nothing. I checked the power adapter and the green light was flashing. I switched the unit's power switch off and the power adapter light went solid green. Turned the power on again, nothing - green LED on the power adapter starts flashing again. Tried several different outlets, same result. When I switch the FH on, no lights on the FH at all, power adapter LED flashes. Turn the power switch off, power adapter LED goes solid green again.
