Just noticed that my TV right before a DVD starts shows a lot of colored vertical lines. After the start they go away. I wanted to stream music from my Roku unit but the TV had so many vertical lines I couldn't read the Pandora listings. The SAT TV video goes directly to the TV and audio optical to the receiver with no problems. I wired the DVD player directly to the TV with no video problems. I changed out HDMI cables, still the same problem. Is my receiver bad?
