Question about Harman Kardon AVR 130 Receiver
I hooked up my AVR 130 as the amp for a new polkaudio soundbar for a flat panel tv. although i'm still uncertain what mode i should be using for best results it sounded great. for a day. now i have to turn the volume on the HK to eleven to get somewhat decent audio. read the manual, installed correctly, checked the cable box settings as well as the television but nothing helped. i noticed the remote had some issues at the same time...turned on the hk instantly but then had to mess around with the new batteries and squeeze hard to get a response. remote works ok now but sound..not so much.

Hi, your analysis are right, your speakers has no problem, the problem is in your receiver.
there are several factors that affects it, try some troubleshooting: and answer this questions:
1. During this event, what is the source of your INPUT audio signal?
Have you tried to replaced your RCA cables that connected to the source of your receiver?
If YES, then problem really exist in the internal system of your receiver. may be you have overdrive your receiver unintentionally, which cause the Power Amplifier to malfunction,
On this event, I would suggest that you bring your receiver to it's Service Center for repair,
This problem needs technical troubleshooting of a qualified technician.

You seem have a problem with a component in that channel, the bad news is that it is hard to fix that type of problem (you would be better off if the channel died). All of the components in the final output section are part of the same audio loop (per channel), which makes it hard to find the faulty part.
Sounds to me like a bypass or coupling capacitor is faulty or need to be re-soldered, either way to fix this problem you should take it in to a repair shop.
I hope that helps and sorry for the bad news.

Check the speaker 1/2 buttons that turn the speakers on and off, they have a habit of getting corroded. Click them in and out about 20 times each.
Play with the balance knob, run it side to side about 20 times. Turn the unit off and do the same with the volume knob.
Ensure mute is off.
Check that the tape monitor is off.
Check that you are on the correct input.
I cannot remember if the MK2 had pre-out to main-in bridges on the back, if it does make sure they are pluged in all the way.
Let me know if this helps,

This is an indication of an internal problem. Typically this is shorted output transistors. Expect a parts cost in the $25-$40 range for this repair.
