HDTVHome Theater Help

Hi guys,

I have a yamaha rx-v461, a hitachi 42" plasma, and Verizon Fios. My cable box is connected to the yamaha via optical cables. For some reason, only on HD channels, and ONLY SOMETIMES, do I get a horrible crackling sound through all of my speakers. I've tried these things:

-switching the fiber optic cable
-exchanging my yamaha box
-and it even did it when i had comcast so im ruling out the cable box
-ran NEW cable coax to the box

Its extremely frustrating and I dont know what to do next. Ive checked all of the speaker wires and they are fine. The fact that it does it sporatically makes it even more frustrating as I cant always trouble shoot. One thing I did notice, is that if a program is making the noise it will not stop until another program comes on. Also, if I DVR a show the DVR will record the crackling sound as well. The crackle WILL NOT come through the tv, only the yamaha. Very Very weird. Thanks for any help whatsoever as its been driving me nuts.

Re: HDTVHome Theater Help

When you wrote "exchange Yamaha box" do you mean that you tried a different receiver?

It sounds a bit like the digital signal is hashed up....do you also have a picture problem when you have an audio problem?

Have you tried a different cable box? Having this occur with different providers doesn't rule out the box, unless you had different boxes, of course.

I didnt try a different receiver, i just swapped out mine for the exact model. Also, when i switched providers I also switched cable boxes. The picture seems to be just fine.

Re: HDTVHome Theater Help

Well, I'm stumped. It sounds as if you aren't getting a decent digital audio connection, or are losing the signal, or the receiver just cn't handle it.

I would suggesst testing each step in this chain with components that you know are good...but it seems like you tried most of that already!

Damn, well thanks for trying to help me out Chuck! It's quite irritating to even try to troubleshoot since its sporatic. Oh well, its not the worse thing in the world,but it just is a nuissance!
