    it will not have a complete firmware.
    can you re upgrade or put the old firmware back on?

SOURCE: harmon kardon avr 25 II

hey i also had this problem, i don't know the name of these but they are basically plugs that you have to block output from the front rear and center speakers of the white/red cables... sry for bad description but its on the left side when looking at the back of the receiver, while all of the other speaker wires should be hooked up to the right with the twisting knobs... it took me forever to find this out but yeah it was a simple fix

SOURCE: cannot get dts from my Harmon Kardon AVR 300 via my Blue Ray

I'm not sure if this solution is still necessary however:

I own a H/K AVR300 and have a PS3 hooked up via HDMI to the TV and Optical TOSLink to the receiver. I have no troubles selecting between DD 5.1 and DTS 5.1. I can even select trueHD whatever format but I can't detect an audible difference, I think that mode might be downgraded back to regular DD5.1...

Hope this helps...

SOURCE: was using the harmon kardon avr 225 receiver and the front panel went out. .... screen display of the channel number, volume, or menu item does not work. ...

Try hooking up a yellow video wire from the back of the AVR 225 Monitor out. Should be at the end of the 7 or 8 yellow video ports on the back of the stereo. Next plug the other end into a yellow video in on a t.v. Get your remote, (Harmon/Kardon) and make sure the t.v. is on the correct video input and hit the OSD(on screen display) button on your harmon remote. There should be a setting in there that says VFD under ADVANCED menu option that allows for turning the front of your stereo lights on and off and dimming them half way also. OFF/HALF/FULL are the 3 options I believe.

If this doesnt solve it your display may have crapped out on you.

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: Harman/kardon avr 247 no audio or LED display on the reciever

I've had the exact problem. HK in the states is no help, you need to deal with a company in Montreal (Jan Industries). Regular techs are unable to fix it without schematics that only authorized dealers have and the manufacturer. This problem happened to me just after 2 years and outside warranty. I've bought a Yamaha today.

When i turn on my harmon kardon avr 165 it shows ''Protect'' and then it turns off again?? what can i do :)


I would try disconnecting the speakers, then turn it on. If protect still shows with no speakers connected, then it needs to go to the repair shop- Might be a blown power transistor.

My Harmon Kardon AVR 2600 goes to protect mode when powered up. After many tries it will fire up but at times it's up to twenty times. I did load the software upgrade 6 months and it has been fine


Check all speaker wiring for shorts, if okay! there is a problem in the audio output stage of the unit or the protection circuit is not working properly. I would suggest a pro to evaluate.

Just bought a Sharp LED TV and there is a slight delay between hearing sound and seeing lips move. Have cable box hooked up to tv by HDMI and have cable box hooked to AVR (Harmon Kardon AVR125) by optical...


Hi if there is an optical out on the television i would use that direct to your Harmon Kardon AVR 125, the sound would be in sync with picture, as the source is the same.

I have Harman kardon AVR 630 and I have trying upgrade for better performance but during the upgrade the problem occured. I have contacted the harman service it seems a lot of money required.


If it failed during the upgrade after it flashed the memory and before it reinstalled the new firmware it has to go in for service. And it will be over 100 USD. est.

Harmon kardon 745 displays "unlock" no sound for tv or movies


I also had this UNLOCK message on my Harman Cardon AVR 130.
The reason for this error was - in a hurry I've plugged the optical input into optical OUT! Double check that your connections in the back are correct and hopefully it fixes your problem.

Cheers,
Sergey
