Question about Harman Kardon AVR 325 Receiver

1 Answer

Hi, I have a Harmon Kardon Model No. AVR 325 that keeps clipping. When I push the power button the display turns off like a second after I push power. Seems like its a easy fix. Nothing if fried visually on the boards and I can't find the fuse. Everything turns on for a second but turns back off by its self. Any solutions?

It sounds like Amp burned, but not all burn parts you can see, you have to measure them by DMM. I guess at least one AMP transistor shorted. you can check SPK terminals by DMM DC, it can be easy to find different with other one

HOW TO RESET HARMAN KARDON AVR70


Hi, Try this. Hope this helps and I have the link here to the manual.
Processor Reset
If the AVr behaves erratically after a power surge, first turn off the front-panel
main
power switch and unplug the Ac power cord for at least 3 minutes. plug the cord back
in and turn the AVr on. If this procedure doesn't help, reset the AVr's processor as
described below.
note: resetting the processor will erase all user configurations, including speaker and
level settings, and tuner presets. After a reset, reenter all of these settings from your
notes in the Appendix worksheets.

To reset the AVR's processor:

1. press the front-panel Standby/on switch to place the unit in the Standby mode (the
Standby Indicator led will turn amber).
2. press and hold the front-panel Standby and memory/folder buttons until the reSet
message appears on the front-panel message display.
3. press the memory/folder button again to reset the AVr's processor.
If the AVr does not function correctly after a processor reset, contact an authorized
harman
kardon service center for assistance.
to locate an authorized service center,
visit our web site at www.harmankardon.com.

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.

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

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.

Harmon kardon avr 125 shuts down


If you want to fix it:

It must be a contact problem arount the power switch, power cable, fuse or the condensator area.
Maybe you can se a black color on the board.
And checking the solderind points with a magnifyer can help too.

Thats all from that distence.
