missing DTV channels on a VIZIO i have cable from comcast? - i cant find channels 30 thru 84 they dont appear after scanning no matter how many times i do it.

Best Answer: Do you have it connected to a cable box or is it connected directly to the tv coaxial input without a cable box. The reason i ask is because the Vizio will do both, Scan via antenna setting or cable setting. Either way, you still get the channel. This is assuming your TV set has the digital clear quam tuner and NTSC/ATSC. Hope this helps. - Francis P

Some channels will be skipped if they are scrambled. Those channels are usually part of another package, and you'll need a box. I have a new Vizio with a QAM tuner, it gets lots of digitals over comcast and the locals in HD. but if I want all the HD Fox, CNN etc, I have to go to the box. - Sound Labs
