I just picked up this receiver that came from my Aunts house. I plugged it up and it displays TV/DBS Protect. What can I do to fix this? Also, I brought this home to hook it up to my existing equipment and to possibly replace my Denon AVR800 Receiver. The Denon is a 3CH receiver and I would like to upgrade to 5.1 if I can get this receiver working. My Denon is putting out about 65W per channel. Not sure how much the Sony will put out. The receiver didn't come with the manual or remote. Can someone give me some specs and how I would go about fixing the Protect mode problem? Thanks.
