Usually when a signal is received the sub activates (blue light) immediately. Amplifier Failure. This is also another reason why your Harman Kardon is blinking RED. If Amp failure is the problem, you will notice the RED light blinking immediately you turn it on. Amp failure is most time caused by the failure of the output transistors. If at least one transistor fails, the DC voltage on the speaker line will lead to the Conclusion.

Hi everyone: I just bought a new setup: - ASUS B350M-A. - Ryzen 1400.

I can hear the sound properly on both right channels, but in the left one, are completely muted I have successfully fixed my Onyx 5. The status is that every time I connect the charger, the LED remains solid RED, but I am unable to turn it on. When I unplug the charger, the RED LED simply turns off, and it still won't power on. It only works when I press the power button and play button simultaneously. The primary purpose of this thread is to share information on the self-diagnostic tools available from the Harman Kardon (HK) radio in your ’06 or newer fairing model bike. It will describe how to operate the radio to display Diagnostic Trouble Codes (DTC’s), list the DTC’s, and list the “Symptoms” (e.g. AVC not working) for which Audio upgrade Gen5 Harmon Karden. Two fairly recent threads here have focused on audio system upgrades to Subaru Outback Gen5 with Harmon Kardon factory audio. This HK “factory” amplifier and the StarLink system combine to create a set of challenges/options that are not fully understood - even by many experts - like Crutchfield.
