Please rate this solution. Thanks.

Are you using the HDMI for the Tivo and the Comcast box? If you do, then you need to verify that the HDMI sound set up at the boxes and at the TV are set to send and use the audio through the HDMI ports, not through the analog ports since HDMI allows you to use either analog audio or Digital audio through HDMI cable, you have to choose.
Please read the Tivo, Comcast box, TV setup for details.

Hi and welcome to FixYa

Initially, postback the model number of the Comcast digital adapter and the TV.

Offhand, if the Comcast digital adapter is connected to the Sony through a coaxial patchcord, then the Sony would really have to be set to Ch 4 (or 3). Channel selection is done on the Comcast digital adapter. It is not possible to record one channel while viewing another.

Good luck and thank you for asking FixYa

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. . .

Have you hooked it up and just tried it. Comcast supports Tivo. If you do indeed have a scramble problem I believe there is a hack for it.

I am having the exact same problem! I am a college student and do not have the money to pay for cable. We have comcast internet in the house and somehow, through some miracle, the cable is on.
Has been for a year. But now i have lost half of the channels. How did you solve it? is there anyway to not go through comcast?

I was just reading everyone’s comments regarding not being able to find the Emerson LC320EMXF 32′ LCD TV code for the Comcast DC50X Digital Transport Adapter. I’m using the Sylvania code of 11864 and the Comcast DC50X remote seems to work fine. Hopefully it’ll work for you as well.

your tuner has failed;
time for another set the cost to repair is too high

There comming out with a udate stay tuned, and please check your cableing as we discussed in chat earlier, and rate this one too thanks..

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

I don't think you can use that box with Comcast, even if you were to get that lock pin removed, it still would not work with Comcast. The lock pin is easy to remove if that's a Comcast box, but the reps just hit a button on your account and it clears it. If the box is not able to be added to your account then they won't be able to remove the pin. Why don't you just get the DTA's for your TVs? You get 2 for free and you can get channels 2-99. What channels are you missing?
