Xfinity Channel Lineup and TV Guide by Comcast

If you're referring to your xfinity tv receiver (the cable box) there's a few different ways. Please keep in mind without much information, it's difficult to give a 100% direct answer.

There are four ways to connect it. We'll start with what will give you the best video quality, going to the worst.

HDMI cable: A single cable with a flat end. Your TV and receiver will have port labeled "HDMI". You plug it in, and then use your tv remote to set it to the HDMI channel. You may have source or input button on the remote. Press that, and a list of options will appear on your tv. Select HDMI. If there is more than one HDMI (as in HDMI1, HDMI2) try each one until you get a picture.

Component cable: A cable with 5 ends. They're color coded, so match up the colors. Then try that input our source button to select the COMPONENT option on your tv.

RCA cable: A cable with three ends. Color coded. Follow the same directions as above in regards to the correct "channel" to put it on.

Coax: A single cable, an end that screws in. Its connector will look like something can be screwed on it, with a hole in the middle for the pin to go into. Connect it, then tune your tv to channel 3 or 4.

No a standard digital box puts out a resolution of Mpeg2 the HD box can out out Mpeg2 or Mpeg4. One is DVD quality the HD is HD. So standard digital is hundreds of lines per square inch and HD is thousands of lines per square inch. Huge difference between the 2.

No HD channels on a DCT700, you have to have a HD capable box from comcast. Usually $8.95 a month for box rental. Don't know a lot about DVD players. If you get a comcast HD box, and have an HD TV, you should use an HDMI cable for best picture. Second choice is component cables. Those are the red, white and yellow or red, white yellow, blue and green cables.

IYou have to have your comcast box tuned to a channel that is broadcast in HD. On your Comcast remote hit menu. This will bring up several icons, one is HD. Select that icon and it will bring up the TV Guide for just HD channels. Select one and tune to that channel. Once your on that channel use your original remote and hit menu, then advance features, then go down to video display and change it from 480 to 980 or 1080. Let me know if this helps.

I had the exact same problem on a brand new Insignia 26 " LCD with DVD. Comcast tech was able to fix it by changing the Comcast box diagnostics. Here is what he did. Using the Comcast remote with the TV on - press power, cable, menu in that order. A comcast diagnostic srceen will appear. Select Additional HDMI options, then audio options. Change the audio options to L-PCM. Press power again to exit the diagnostics. That will fix it and you get to use the HDMI cable.

Your TV may not support your HD channel signal. Check with HD DVD & non-HD DVD players to confirm.

I don't know if this will help you or not, but we had that problem, and it was a loose connection. After all cables were plugged in tight, on both the receiver and TV we had color again.
