It would have been faster and easier if you had mentioned that 10030 partially works in your first post.....

The DTA remote is intended to run your cable box, so the only buttons which are supposed to work with the TV are Vol+, Vol-. Mute and Power. Sometimes power doesn't work well, because it sends the power signal to the DTA at the same time, and that can confuse the TV.

If you want more control of the TV and also the DTA, you can try to find a Comcast 3DVR remote with a red OK/Select button (grey won't work with the DTA) or buy a RCA RCRP05B ($20 at Walgreens and Best Buy). A OneFOrAll URC-8820N will also work.

For the DTA use Cable 1982 (or 01982 for remotes needing 5 digit setup codes). If you get one of these, post back and we'll tell you how to manually program in some functions like the arrow keys, which probably won't work using (1)0030
