Question about Harman Kardon AVR 320 Receiver

1 Answer

Goes into standby mode

I own AVR 320 receiver which is around 5 years old.
Last month, when pressing power button it goes into standby mode for no apparent reason, within 2-3 sec. After pressing the standby button for couple of time and it turned on and remained on.

Last week, it had gone into standby mode again as earlier.
However, this time when I tried to turn it back on, it would not stay on
and kept going into standby mode. I checked all connections and they
looked fine.
When contacting the Harman Kardon support team, the suggested the problem is probably located in the power supply. This explanation was of very little help to me.

Try this.
To reset the AVR's processor:
1. Press the front-panel Standby/On switch for more than three seconds to turn the AVR
off (the Power Indicator will turn amber).
2. Press and hold the front-panel Surround Modes button for at least 5 seconds until the
RESET message appears on the front-panel Message Display.
NOTE: After performing a processor reset, wait at least 1 minute before pressing any
Source Selector buttons.

Good Luck

Denon AVR-3200 wont go into standby mode

Not sure what you mean by standby mode. The power button on most of the audio remotes I deal with merely turns the equipment on and off.

Denon AVR-1908 won't power on

Are you getting a standby light at all? Is it flashing? Do you here a click when you plug the unit in? If the answer is no to all of these then you blew a fuse. If you do have soome sort of standby light, then your set is in protect mode. More than likely for a blown channel. If no lights, but you ar egetting a click, you could have a bad transformer. Use a DVM and see if it is open or not. Good luck

Seems you set it to "Stereo Direct" mode. This is an analog only mode, while you are using a digital signal. You can change this with the mode button.
Press menu, on the main menu screen 1, scroll down to stereo direct. Turn this OFF.
This should solve your issue!

Try this, not sure if the same would work for ya.

Swich off the amplifier.
Prior to the process check the wires connecting the speakers are not creating a short circuit which is apparently putting the amplified into a standy mode.

1. Press the "A" "B" and power key all at the same time and hold on to it.
2. The amp will go into a reset mode and will keep blinking till it gives a normal "click" sound and the amp turns on.
3. this process would take about 2 - 3 minutes.
4. You may then release the buttons.
5. If it goes into a standby mode again and does not power on, or the standby keeps blinking, get assistance from the engineer.
6. Once it is on, you shall need to do the resetting of alll the configurations done earlier.

Hope it works, it costed me 3k to get the job done.
