tv picture frozen on samsung smart tv
Does your television work off the antenna for local stations? Can you play movies off a Blu-ray player? Can you use the You Tube app off the Broadband?
If these don't work the problem is with the television. Read the Samsung manual and directions that came with the tv. The is a menu under Support to allow Samsung to trouble-shoot your television over the Internet.
If those work then you may not be set up correctly for the cable-box. Comcast can help you there.
