Comcast cable channel one off from Tivo channel

I've never, ever heard of this problem - having been a happy TiVo user for over 15 years. The very first thing I would do is call Comcast and tell them what is occurring. How long had everything worked OK before this happened? If things were OK for a long time before this, and if your TV carrier was, likewise, Comcast for a long time; and if you haven't gotten a new TV or cable box for a long time, then the problem must rest with Comcast. It must!
In our home, with the number of movies, shows/sporting events/etc. which we record, that would be totally unacceptable!

Try this: Unplug everything (with everything turned off). Make sure your TiVo remote is good (fully charged batteries and the code is right for your TV/cable box), Wait for 10 minutes and plug everything back in, starting with TiVo, then the TV, then any other accessories.

Plug back in and do a complete restart from scratch - like you did when you first set up TiVo.

Make SURE that your receiving channel (3 or 4) is the same on both. It could be that someone accidentally has changed it - are there kids in the house?

If none of this works, get Comcast in there. That's all I can tell you. . .

I have a comcast digital converter box and i need the manual to hook it up to a tv

Here is the easiest way...

1. Connect coax cable from the wall to the "Cable in" on the cable box.

2. Connect a coax cable from the back of the TV to the "To TV" output on the back of the cable box.

3. Tune your TV to channel 3

4. Plug the power cord into the back of the cable box and into a power outlet.

5. If you do not have a picture call Comcast and ask them to send a signal to activate your new box.

6. Enjoy your new programming.....

Good Luck...

I'm thinking the Comcast DVR box maybe putting out weird HDMI signals and the TV can't translate it. I would call the Comcast people on this one.
In the meantime, I would try finding another source the uses a HDMI cable to rule out the TV as the problem. Basically, testing the TV to see if the problem still happens when you use something else than the Comcast box. Try a Blueray player, Playstation 3, or Xbox. Just something that uses a HDMI cable.

Colors Off with High Def Comcast Cable

check your cable connections between tv and box, especially the red connector, try unplugging and plugging back in the cables.
