Avr 125 no audio - Harman Kardon AVR 125 Receiver

You have blown your output transistors this is about a 125 to 150 repair

Hi...

Find someone that does TV or audio repair and have them open it up. A cable assembly may have loosened during the MOVE.

Cheers

It is normal for any amp or reciever to make a click while changeing inputs, Or a Function. From one thing to the next, As long as it is not a real loud pop though the speakers.The click is normal end noyhing to worry about.

try out a external moritor that check the video card or the back ligth lamp

The manual talks about that.

Any of the three INPUTS if you're bringing sound IN from the TV or elsewhere; or the lone OUTPUT if you want to send audio to the TV or elsewhere.

If the former, consider sourcing the audio from the REAL original source of the program you're watching, most likely a Cable Box. Less cabling and fewer connections to fail.

There is no mention of any fuse in the owners manual (downloadable from the link below)
You could try plugging an external device into the unswitched ac outlet on the rear panel to check if ac power is actually reaching the unit.

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.

Go into menu setup on ps3 and check off the option boxes for audio. Also make sure the optical input on receiver is set.

Check and see if you don't have a auto dim setting on or you changed Display setting.

I have same Amp and this happened to me also.

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.
