ONKYO TX-DS575X - Speaker B not working

Hello, since the center speaker works now after it was replaced I would suspect the speaker. Thank you, Onkyo USA

Check the Ohm value (4, 8, 16...) on the speaker and on the ONKYO too.
If not the same that is the (big) problem!

You might try this replacement

Hi,
Please reset Onkyo receiver that will solve noisy sound problem, to reset the receiver, press and hold Video-1 button on unit and press Speaker-A button. Display will show *Clear* that means receiver has been restore on default settings, turn it On and check sound.
Hope this will help.
Thanks.

It's in the manual, which you would need to use all its features anyway.

1) I bought the same Onkyo model from goodwill a couple years ago and it had the same problem. The solution is simple: Get yourself some Deoxit D5. This is a spray that will clean out all the oxidation in the volume pot. To do this you'll need to remove the cover of the receiver. Deoxit can be bought at guitar shops, or if you know a musician they might be willing to do it for you.

2) User manual is available for download, for free. Google "Onkyo tx-906 receiver manual".

You have to raplace IR sensor PIC-26043TE2 or similar and should help.

did you swap the left from speaker with the left front?
if still crackels after that them you have bad left output.
