TX-NR609 displays blue screen

My tx-nr609 displays a picture with no sound or just a blue screen when I turn it on and have it set to cbl/sat. If I change it to DVD sometimes it will display a picture sometimes it will be a blue screen too. If it does display a picture on DVD and have sound sometimes if I switch it back to cbl/sat it will display a picture and have sound and I can watch tv. I have had this unit for about 6 months to a year and it has worked fine in the past. No recent changes have been made. After the problem started I upgraded the firmware last night and I am still having the issue.
Thanks
