Receiver not working

Recently i have moved my Harmon Kardan AVR 5000 when shifting my residence. Upon switching on the system, the Input Source and the Output Source do not display on the display panel. The system is not responding at all. I had connected my DVD player and the speakers including the Sub exactly the same way as it was earlier. I had tried all possible trouble shooting looking at the manual and also done a system reset, but the problem still remains. I have connected my JBL Speaker+Sub and JVC DVD Player to the receiver.

SOURCE: I have sound when I play the dvd or the cd player

Sounds like the setup info got scrambled in the receiver. Re-program the TV input...from optical or coax or whatever way it is going into the receiver.

Does the Harmon kardan avr25 have an hdmi output

Nope. You get one component OUTPUT (monitor) and two component INPUTS (Vid 2/DVD) but no HDMI video output.

If you can input and switch HDMI video directly at your display from your cable/SAT etc. you should be fine, just run all the audio through the AVR-25 through the coaxial/optical digital inputs, L/R analog RCA or the 5.1 direct inputs.

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.

Harmon/Karden AVR 230 Surround Sound Receiver

Use your remote to get into the Menu. Look for something called audio, or audio properties. In there you can choose your inputs (sources) and output choices.

On the remote itself, there should be a button called input, or source. That would be for things input to the TV.....such as dvd, vcr.

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.

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.

Humming noise

Usually Humming noises come from frequency interferance.  In this case it is being caused by your input sources.  A smiply solution is to replace the cables and or seperate the source cables away from any electircal cords or sources.

No sound

You need to have an input audio source on your receiver such as a DVD player or ipod. The radio is an internal source that is why yo uare hearing sound from it. One thing you could do is run a cable from the audio out jacks on your television to an input on the receiver, and then when you are watching TV select the input you put the cables in to hear the television sound through your receiver speakers.

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.
