You have a bad amplifier section and your unit will need to be repaired by a technician. I would disconnect the speakers to prevent possible damage. In some cases components in line with the transistors will be bad in the amplifier also. There is no way to tell without electrically testing the unit in shop. Estimated repair cost would be in the 60 to 80 dollar range depending on the number of parts that are bad and the labor rate in your area.

Harman kardon 990 error


Hi i dont know if you found your solution but you can solve this on your own.
on the front there is two buttons you have to press and hold in standby mode. The "Level settings"button and the "speaker 1" button. when you do that you reset the firmware.

I have a Harman Kardon AVI 200 ii, when i turn it on it turns on like 3secs and then it automatically it turns off, why is that?


It is going into protect mode. You may have shorted speaker wires, you may have an internal short in a capacitor either in the filter section, or those on the output.

My Harmon kardon is stuck in protect mode


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Double check all connections .A thumbs up would be greatly appreciated if this answer is helpful to you. Worth fixing.

How are you? For HK990,How to do bi-wiring connection of the speakers? thanks


Sabve your money - it's BUY-wiring.

http://www.harmankardon.com/resources/Brands/harmankardon/Products/ProductRelatedDocuments/en-US/OwnersManual/HK%20990_OM.pdf

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".

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.

I have **protect** in my kardon harman avr85?please give me solution


It could be a short in your speaker wire or the crossover in your speakers.

1) Turn off your unit and disconnect your speaker wires at the amp, if the protect is no longer displayed when the unit is turned back on, check the connections on the speakers. If you do not visually see a short on the speaker wire connection, turn off the unit and disconnect the wires at the speaker and isolate them so they do not touch then connect the speaker wires at the amp. Turn on the amp and see if the protect is on. If it is on, the wire has a short somewhere in the line. If the protect is off then suspect the speaker has a short in the voice coil or crossover.

2) If the protect is still on after you disconnect the speaker wires at the amp, it could be the power IC in the amp is shorted and needs to be replaced.

I own my harman kardon 620 amplifier for about 8 years. Now the sound from the speakers comes on and off intermittently. I have connected and disconnected all the cables to the speakers but it still has...


The problem is in the audio circuitry, there are bad solder joints on the board that need to be addressed, from your description it is a intermittent issue with the sound. Since this a high end unit I recommend a top audio technician to work on your amplifier, and I suggest not using the system until it is repaired because the risk to the audio output parts getting damaged is high and they are pricey.

I have a Harman Kardon Signature 2.1 amplifier that wont start. Its LED flashes red and yellow indicating that something is wrong. Does anyonehave any idea why?


I work on power amplifiers and I can offer a few suggestions
The flashing light means the amplifier is in "Protect" mode.
This could mean one of two things: 1. The speakers are not connected properly or, 2. There is a component failure in one of the output amp sections.
It might be as easy as a blown fuse in the circuit that powers one of the amp sections.
Not knowing your technical background , I can't say much more about opening the unit and checking for certain things
