I have an H/K AVR310 hooked up to two JBL ND310s via the front channels. I also have a powered sub on the sub preout. This is the setup I have here at home that just sits here while I'm at school. Well, I just returned for Thanksgiving and everything was working fine. I play music from my nForce2 using the digital encoding. All of a sudden, the right channel just dropped. I tried playing music from the CD player, same problem.
I reversed the speakers and confirmed that the right speaker does work on the left channel and the left speaker doesn't work on the right channel. When I turned the balance all the way to the right I had no sound at all. The sub worked fine so the preout still works. So I started playing with the speaker wires, reconnecting them and such. Then the left channel dropped and I got some of the right channel to work. However, when I turn the volume up to listenable levels I heard what sounds like static. I reset the CPU but to no avail. I then hooked up two small AIWA speakers to confirm the speakers aren't the problem. No sound from the left channel on the AIWAs. This was before I went to bed last night.
Last night the receiver was turned off. When I turned it on this morning the right channel sounded completely normal. It was loud with the proper reproduction. Nothing out of the left channel. Well, I left the receiver on when I went to eat lunch and when I came back the right channel is barely on and there is *some* sound from the left channel but for me to hear it I have to turn the volume up and there is static from both channels. It seems the longer the receiver is on the worse it gets. I don't think it's wiring because it was fine and then everything just died.
I got this receiver refurbished from H/K's online outlet
www.harmanaudio.com. The receiver arrived dead so I've already had it repaired once under warranty. I checked the website and found the nearest authorized service center and called them. He told me I probably messed it up by using 4 ohm speakers with the amp. I told him my speakers are 8 ohm. He then told me that he believed my warranty was up because H/K only offers a 90 day warranty on refurbished goods which doesn't sound right to me. He quoted me a price of $50 just to look at the receiver. So I'm afraid the only service center in my area is going to try and swindle me. If the problem is internal, should I try to fix it or just get a new receiver? Thanks for the help.
