I feel really stupid asking this as I have a Sammy 52A750 coming next week and I am setting up my PS3 through HDMI, but I am having a problem hooking up the PS3 to my old CRT TV. First off, the TV has no AV inputs. I am using Time Warner Cable and the Scientific Atlanta 8300 DVR/Digital Cable Box. Since I have no AV inputs on the TV, I have no place to connect the PS3 other than the front of the cable box which has the standard red/white/yellow AV input from component. However, after connecting the cables and setting everything up, the PS3 won't play. All I get is the black screen you get when nothing is on a TV. I've tried channel 3, digital cable on/off, etc. I just don't get it.
