Hissing from Center Channel (1 Viewer)

[Frank Abeyta]

I'm hearing a loud constant hissing out the center speaker.

I tried switching speakers & speaker wire.

The receiver is a 6-1/2 year old Sony STR-DB830.

I'm pretty much resigned that I may have to replace receiver but wanted to see if there's a possible solution that I'm overlooking?

All receivers and preamps have noise. The key is to have a signal to noise ratio large enough that the noise (hiss in your case) is not audible. It does sound like it's time to upgrade/replace the receiver.
