As of yesterday when playing a vinyl I noticed my front left channel was practically mute. Tested on other inputs, have switched the front left and right speakers to check for bad connection/dead speaker, issue is consistently with the front left channel.
When I go to the manual audessey etup and play test tones, all channels play static as they should except front left. However, when I go to factory reset the receiver, and it’s going through speaker connection&testing in that menu, I found that it was playing the front left test melody, just at MUCH lower volume. I had to crank it up to 65 to hear it, and then moving to the other 4 speakers+sub those channels were twice as loud at the same volume atleast. So clearly the channel is not just fully outright blown, are there any suggestions to try or is it just on its way out?
