Onkyo TX-SR806 7.1 Channel 300W HDMI Home Theater AV Receiver/ ONLY FOR PART.

I have been using this as my personal unit for over a year.  The speakers have always had a load scratchy noise for the first few minutes when it powers on then the sound clears up and sounds perfect.   So I would always just leave it on so I didn't have to wait for the sound to clear up.   Now the other days it started to cycle sounds through the speakers like it was in a setup mode.  I power cycled the unit a few times but it keeps going back to that strange sound.  

Selling for parts only.  No returns accepted.

Unit is very heavy.  Shipping is set to calculated cost and I can't adjust it.

Comes with Remote but no power cord.
