SOURCE: Harman Kardon AVR 120 turns off by itself after normal work for about 1 min

Do you get an indication on the display where the point of failure might be? It would show up on the LCD speaker diagrams just before shutting off.

speaker amplifier chip may leaky or damage
you are using improper sound driver
check driver status in your computer device manager or just typing dxdiag on run in start menu, check status of sound driver installation

Hi and welcome to FixYa,

Appreciate the direct "Ask Me".

Initially, pls try cleaning the battery terminals. In some instances, it may be necessary to scrape them to remove corrosion. Still there are times they may have to be bent or stretched to ensure that they provide more pressure to the batteries. Alternately, pls try to confirm that the AC adapter is working by checking for the presence of voltage on the plug/connector with the use of a voltmeter.

Should the above not address your concern, then it is most likely that the problem is internal electronics and the unit is simply going into protective mode. You then have a choice of performing a DIY (do-it-yourself) or seeking the services of a qualified professional.

Good luck and Thank you for using FixYa. Happy Holidays.

I have a active sub woofer (akari bazooka) but the only connections available are the speaker connections. The front of the sub woofer has volume adjustment. How can I connect this sub woofer to my Harman...


hi,
You can't connect the pre out of your AVR to this sub woofer. Do one thing connect the frond left/ right channel speaker "B" out of harman kardon to the sub woofers left right speaker in put. you can connect the speaker out "A" to your normal left right speakers. Remember to switch Speaker "A" and "B" in ON position in your AVR. Also do one thing go to the speaker setup of AVR and switch OFF (slelect NONE) the sub woofer.This will disconnect the sub woofer pre our and the sub frequency will mix with frond left right channels.
ok

My HKTS 7 Sub woofer makes no noise,the led burns from amber to blue as normal,and every so often i hear a low rumble noise. The Sub is powered and has 1 cable to the receiver, the fuse is also good.


Subwoofer is center speaker from A+B speaker signals. first check your wire to the receiver. Otherwise you need electronics service on the amplifier inside the speaker.

Loud buzzing noise upon switching on


Do you have a wireless phone near the speakers? It will make the speakers noisy. If this is true, move the speakers away from the phone. Check other electrical devices which may be near the speakers, it may be the problem.
