SOURCE: Harmon Kardon AVR 235 no sound

Ensure that your speakers are connected to the terminals that you have your speaker selector switch turned to.
Then check that you have your device, whether it be a CD or DVD player, or turntable, plugged into the correct input and that you also have the correct input selected on the receiver.

SOURCE: Humming sound (speakers)when HK AVR is powered up.

In my case the buzz was only on front speakers. There are 3 capasitors (100uF/25V) very close to the cooling ribs of 3 regulators in the power supply. In my case the C922 was bad.

HK avr-25 - everything seems to work except sound is not being amplified. What could be the problem?


Check the speaker 1/2 buttons that turn the speakers on and off, they have a habit of getting corroded. Click them in and out about 20 times each.

Play with the balance knob, run it side to side about 20 times. Turn the unit off and do the same with the volume knob.

Ensure mute is off.

Check that the tape monitor is off.

Check that you are on the correct input.

I cannot remember if the MK2 had pre-out to main-in bridges on the back, if it does make sure they are pluged in all the way.

Let me know if this helps,

Cheers,

Kevin

Hi, i am having problems with the multiroom on my AVR 630


Go into your OSD (on screed display).

Go to multiroom.

Change the SB AMPS from MAIN to MULTI.

Make sure you have only analogue sources, it will not amplify digital inputs for the MR.

Harman kardon avr 140 - all displays work but no sound


I have an HK AVR140 all of the displays work, even shows when a digital connection from the Blu-Ray player is connected but no audio comes from the speakers! I found some information that HK does not have DC protection so when there is a problem muting Circuit is initiated on the main Amp. I called HK and they want me to send it in to a service dept that is not close at all. Any ideas? Or is there a way to by-pass the muting circuit somehow?

Powering off by it's self...


It sounds like an overload/no load problem.
Are ALL the speakers connected? to the right places?
If the amplifier section doesnt "See" what it needs, it will shut off.
If all connections are good and it shuts off still take it to a tech who knows stereo. Doesnt have to be an authorized HK guy either
