Have just had a Comcast cable box installed and now need the code for the SONY ICF-CD555TV to program the remote. Can none help?

This is a Comcast baby - U are paying them plenty for the service - they should help you with the remote. Don't let them off the hook.

Find Your Comcast Remote Control Programming Code
make sure your using those codes with the AUX button. Comcast does not have all remote codes for every electronic made though.

Your using a comcast remote with a portable television??

It is possible that this remote will not program to your Comcast dvr. Your DVR is probably newer than the remote and has new codes that the remote doesn't support. The only thing you can do now, is either purchase a new universal remote that supports both units. or use your Comcast remote to program it to your TV. the Comcast remotes are programmable.

The real problem with the Comcast remote is that there is no other brand, it's not like a Sony remote that's relabeled or anything. Fortunately, Google helps again, and it turns out Comcast has a page online about programming the Comcast remote control.
Comcast 3-in-1 remote control To program the remote to work with your Sony TV, you need to take the following steps:

1. Find the code or codes for your TV from Comcast's list [PDF]
2. Turn your TV on
3. On the remote, press and release the TV key on the very top of the remote.
4. Press and hold the Setup key, until the "TV" key flashes twice, then release the "Setup" key.
5. Using the number pad, enter in the first 4-digit code found next to your television brand on the chart. If you do this correctly the "TV" key will flash twice. Now it's programmed!
6. Now point the remote at your TV and press the Power key. If the TV turns off, you're golden. If not, try again with the next code on the list.

You may have to go into setup and ensure that the input is 'CABLE', If you have an 'INPUT' (or TV/VCR) button on the remote, try it.

If you only wish to power the TV off/on with the remote, there is an alternative. Plug the TV into the outlet on the back of the Comcast box. In the Setup Menu for the Comcast box there is an option to make the outlet switched or unswitched. Select SWITCHED then the TV will turn on/off with the Comcast box. The
LC320em9 will maintain the previously selected input.

There is a code out there to try.  The code would be 47.  Just follow the steps in your manual on how to program this box and you should be able to go from there. Can't garantee that it will work as that code came out with the newer tv but it should work.

I used 0111, it worked

The answer depends whether its a Comcast DVR Remote or a regular one. The DVR codes are 4 digit -- the others are 5 digit. I got 0060 to work for my DVR remote.
