Remote Code for Zenith B2510Z?

I'd like to know what the remote code is for a Zenith B2510Z so I can program the remote of my Comcast Digital Transport Adapter (DTA) to turn my Zenith on and off. The codes that come with the Comcast remote guide don't work and it doesn't seem to detect the remote code of the TV automatically. The DTA is a PACEDTA. The part number of the remote that comes with the Zenith TV is SC3492Z.

Thanks
