lcd tv /blue ray question
Dad just got a Sony 120mhz 47" tv from BB. He got blue ray dvd too. Neithe of us are very tech savy. For now he has his non hd cable box connected to it via coax. We are told the picture will be better when he upgrades his cable box. He also has the blue ray hooked up but has not watched a blue ray disc yet...just regular ones. We have noticed when disks play that you sometimes see a vertical line down the middle of the screen. It does not seam to bother Dad but it bothers me. He says maybe its because its not a blue ray disc or a tv setting is incorrect. I say phooey its a bad dvd player. Ideas?
