I have an Onyo TX NR 777 with the same issue. It only happens when watching a DVD or Blue Ray. The sound goes way and it enters a self diagnostic mode and the message Check SP wire appears. I have been able to get rid of it by just turning the unit off. Also a fan blowing cool air on the vents prevents the problem.. onkyo av receiver error "AMP DIAG MODE". this is a common problem with most onkyo home theater av receivers. Reason? onkyo makes the shittiest electronics in.

If the unit suddenly enters the standby state and "AMP Diag Mode" appears on the display of the main unit when the power is turned on again, this function is diagnosing whether or not the main unit is malfunctioning or there is an abnormality with the speaker cable connection..

From there I replaced the speaker wire from the FL speaker, but the crackling still existed and I received yet another AMP Diag Check SP wire message. After reseeding the connection to the back of the speaker, the message went.
