On the front of the receiver or on the remote is a a test button. Pressing this button will play a tone through each of the speakers in turn. When you press this, do you get a tone out of all of the speakers or just a few? For testing purposes, swap one of the working speakers with a non working one and do the test again. Do the same speakers emit the tone?
On the front of the receiver is a button labeled "2/6 stereo." Pressing this button will change the stereo from 2 speakers to 6 speaker output. See if this may also fix your issue.
