I think you can find the answer in your owners manual. IMO your biggest issue is component cables don't give you 1080i or 1080p. You need HDMI cables to get the best possible picture or you're not getting what you paid for.
Here's my question:
I have a samsung 8 series 46inch lcd flatscreen. i'm running Cablevision HD DVR box on component cables. In the menu option, I can scroll down to set up and set up a time when my tv comes on and when it turns off, but it onlly allows me to turn on the tv on "CABLE" or "AIR", which gives me the snow effect with no signal. My TV only gives me picture when the INPUT~source LIST* is "COMPONENT1". How to get this feature to work with my component cables? in essence, I don't get picture via the 'cable' or 'air' option on the 'Atennae', I get it via 'component1', but this timer feature on my tv seems to only allow one to automatically come on via 'cable' or 'air'. help!
