Onkyo HT-R430 no audio output

Using various inputs to this amp, there is no output using any mode. I've attempted the first diagnostic test in Onkyo's service manual (Operation Check-1). When I run down to the "Test 4-21" line, the receiver is to start an automatic test through 4-26, however it does not, it simply stays on "Test 4-21". Does this indicate the test failed ? I suspect my output amp is bad or that the channel transistor(s) may be bad, but I am not sure.

Any other helps available for this same problem?

Thank you!
