HK AVR 125 display strobing and no sound, even in headphone jack

Recently moved and when I powered up my HK AVR 125 the display was "strobing" like scrolling and flashing, and no sound at all. You can read the display between the strobe effect and see the volume change on the read out when you turn the knob, but there is no sound at all from the speakers or the headphones. I tried all of the inputs and even reset the unit using the tome mode button, but no change. PLEASE HELP! I love this thing, and in 10 years it has never given me any trouble.

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

SOURCE: just purchased a used hk 3370,only hear a little

Turn the volume down. Maximum volume is not a troubleshooting tool. If it's silent at half volume, it's essentially source-free. No sense blowing your speakers up when we find the setting that's wrong.

Let's us FM for the initial silence issue. Tune a station.

Look carefully at the front panel. Analyze every indicator.

Is MUTED turned on?
Is a Tape selected by mistake?

I have a Denon avr 391 and it worked fine for 4 years. Now I cannot get any sound out of it. Any idea what's going on. Help


could be a bad headphone jack. There was a commong problem with denon receivers around that time where the headphone jack had contacts that would short and make the unit act like there were headphone plugged in even when there wasn't. Sometimes you can clear the error by inserting a headphone plug and unplugging it a couple times. If it continues to happen, then you can get the headphone jack replaced.

The unit thinks there are headphone plugged in even when there are not. You need to have the headphone jack replaced. This is a common problem with this model. Another way to fix it if you don't plan on using the headphone jack is to unplug the cable going to the headphone jack board. This will disable the headphone jack, and stop it from sending an erroneous signal to the micro.

Can I connect guitar to my Harmon Kardon receiver


Sorry. They are not compatible. The headphone jack is an output but you need an input for a guitar or bass. You will certainly damage the HK if you continue. There are no compatable inputs on the HK. The inputs are meant to be used with a 300mv output device, such as a CD or DVD.

H/p input on display clicks on and off


Need to either unplug the cable to the headphone jack board (if you don't want to use the headphone jack), or have the jack replaced. This is a common problem with these models. The is a short in the headphone jack that makes the unit intermittently think there is a set of headphones plugged in even when there isn't.

Denon avr 688


check to see if there is audio from the headphone jack. These unit have a history of bad headphone jacks that cause the unit to think there are headphones plugged in even when there isn't. Sometimes plugging phones in and taking them out will fix the problem for a while.

Denon 1908 no sound


Try inserting a headphone plug into the headphone jack and remove it. Sometimes these units have a problem in the headphone jack where the unit thinks there are headphones plugged in even when there isn't. This cuts all the audio output to the speaker jacks. If you never plan on using the headphone jack, you can also go inside of unit and unplug the cable that goes to the headphone jack board. Just make sure you unplug the unit before you do this, the plug is close to the main power switch.

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.
