What is the remote code? I can't find the correct code to program my comcast cable box remote.

Check here for a list of manufacturer codes for your specific remote: Comcast Cable Remote Support
Check here for a video of how to get into programming mode: Program Your Comcast Remote
Comcast's remote page seems to be broken right now, but may work in the future: Comcast Remote Codes Program Your Comcast Remote Control

Please post back if these don't help!

I pushed code search different blink appeared pressed tv press code then use on buttons. On all the code

Enter the information and it will give you your codes. I can't do this as I don't know what remote you have.

You should have gotten a folded manual with all of the codes though.

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.

10030 for the comcast dvr remote. Code is from NEC

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.

I had the same problem with my remote. I would enter the code and there would be no response from the remote. I looked up the manual for the other comcast remote and the codes are 5 digits instead of 4. Try codes 10093 or 11602. The reason why there is no response from your remote is because it is waiting for you to enter the last digit of the code. Hope this helps.

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 got a a sharp LC-32D43U and for my motorola cable box i use hte code 31 from jerrold, i take it from the manual and i got it tryin every single code unti i get one that works.

Hope it works for you
