Recently moved. Comcast came out and installed boxes on my TVs. My Samsung does not receive HD signal. Everything else works, just no HD picture on the HD channels.
He swapped out boxes and cables...nothing.
TV bad? Cable bad?
When you say no HD picture on HD channels does that mean you get an SD picture on those channels or no picture at all? If you get an SD picture do you get HD on other TVs? Do you get HD from other sources on the Samsung? Try using the Samsung with on of the other boxes that gives you HD in another room.
If you get no picture at all then try on of the other boxes on the Samsung. The TV can't be at fault.
I get a picture on every channel, just no HD clarity on the HD channels. I do have another HD TV and HD works fine on that one. I took the Samsung and hooked it up to the box and cables that do work with no luck. TV worked fine at the old house with the Charter box. Hook up to Comcast....no HD.
