Return to factory setting may not be mentioned in the owner manual but this is how it's done. Put the amp in st.by mode, push "Speaker 1" & "Level settings" simultaniously for about five sec. The dispaly will than blink and after a minute or so it will say "default param.recalled". Than pull out the cord from the outlet and leave it out for 30 sec. before reconnect. Than turn on the amp and your back to factory settings.

It is unlikely that your have a damaged amplifier. You may have something switched wrong. In your owner's manual, you will find a procedure that says' "Return to factory defaults, or just reset". If that doesn't resolve your issue, or you need more assistance, or would like to inquire about a repair, please visit my website at audioserviceclinic.com. You may contact me there. BTW, I worked at HK. Thank you.

SOURCE: How are you? For HK990,How to do bi-wiring

Sabve your money - it's BUY-wiring.

Bi-wiring does nothing but make you use twice as much speaker wire for the same electrical effect. Bi-amping assumes there are deficiencies in your electronics that must be worked around, again by using more speaker wire and separate amps.

Do some reading on the web about "bi-wiring".

I have a Harman Kardon HK990 which throws an error #005 if I switch it on with a digital input connected. If digital input is not connected, it turns on without any error and all buttons work as expec


If you had a bad amplifier, as suggested, the unit would most likely have a condition known as DC Offset. In this case, the amp would immediately shut off. As you said, the amp stays on, but you have no sound. First thing I suggest, turn the unit off. Listen carefully to the top of the amp. When you first push the power button, you should immediately hear one click, followed by a second click, within 5-20 seconds. If you hear that second click, you amp is likely not bad. If you don't, then you do most likely have a blown amp, with engages the DC Protection circuit to the microprocessor(computer within your unit).

Next step is to open your owner's manual. In there, you will find a procedure called, "Return to factory reset, or default". Follow that procedure, to reset the unit back to the factory settings. Those inputs are assignable, meaning that you can make certain inputs, analog or digital. You may have set one wrong by mistake. The reset will fix that. If you need more assistance, or would like to inquire about a repair, please visit my website at, Audioserviceclinic.com. By the way, I worked for HK, JBL and Infinity. Thank you.

1.Is the fault caused by an optical or coaxial input or both?

2. Have you tried a Firmware Reset? (press "Level Settings" button & "Speaker 1" together.

3.Do you have a Service Manual (I have pdf!)

It runs so hot why?


Possibly lack of ventilation or excessive volume through difficult speaker loads.

http://media.onecall.com/Image_Products/Harman%20Kardon/harman-kardon-hk990.pdf

See page 6.

IMPORTANT: When connecting two pairs of speakers, determine the impedance of each pair

by looking on the back of the speakers, in your owner's manual, or by contacting your dealer or manufacturer.

You can listen to two pairs of speakers at the same time ONLY if the impedance of EACH speaker is NOT LESS THAN 8 Ohms.

WARNING: Do not play sets of speakers simultaneously except as recommended above.
Amplifier may overheat.

Left channel won't play.


There could be a number of causes for this from as simple as a dirty switch to a power supply feed to the left channel being open. Without looking at the unit, it is had for me to say. Is it worth it? In my opinioon, yes. Figure on $5-$25 for parts.
