Jul 14, 2009 - Audio Video Troubleshooting 101: Get your AV System Working Again. ... It's time to put on your propeller head and get down to the business of fixing your system and enjoying it to its ... Problem: One or more of my speakers isn't working ... your Blu-ray player to your AVR and let the played do the decoding.
turn on your video and start something playing, press the speakers button repeatedly until the sound comes back. this should bring back your front speakers, if it doesn't, double check your speaker connections and sound field program.
the speakers button should cycle through all available front speaker options.
With what signal did you try? Maybe your signal source (DVD/TV or radio) didn't contain any sounds for the center channel. Go to the Setup menu, Speaker setup / Manual setup and find there item called "Test tone". It will output a test tone to each speaker individually (you will see on LCD which speaker is being tested at each moment). If you will hear a sound from the center now, there is no issue and center is working fine, just your source didn't contain any sound for the center.
If it doesn't work, then either you have faulty cable, faulty speaker or faulty center output of the receiver. - Try connecting the center speaker to different output of receiver (this will test if speaker is OK). - Try connecting working LEFT speaker to left output with CENTER cable (this will test if cable is OK). - Try connecting working LEFT speaker with working cable to the CENTER output (this will test the output of receiver if OK - but use the Test Tone from Setup).
Is your center mode set to "Phantom" instead of "Normal" or "Wide"? That would split the mono Center channel program and mix it equally with the programs for both front speakers so your brain would believe it's in the center.
if the sub was popping that either means the sub is getting to much power and blown that normaly happens when they pop, for the center speaker could check the wires maybe it came undone that could be a possibilty
1-disconnect subwoofer first and test-and then disconnect surround speakers-and front speaker after-and later center speaker.ever time you disconnect you check the operation until you find the bad one(or two)which make the problem change its cable first and then change speaker itself.if all above failed contact the service center.
