Hi and welcome to Just Answer. I will try my best to give you a precise and accurate answer.
The Sony codes for what? A universal remote maybe?
Ok, take a look at the following page. On it is a picture of most of the Comcast remotes. Find yours and then click on View Manual and you will get the code list.
Here is the link: http://www.comcast.com/corporate/customers/customer_support/remotes.html
Now, if the codes don't work, come back here and I'll try and help you further.
Let me know.
