remote code for Insignia 19 inch

Just set up a Insignia 19 inch (NS19E450WA11 ... probably the same as the NS19E450A11.. only the white version).

Everything is great,.. except...

I can't find the remote code.  I have searched the models listed in my manual.  Nothing seems to work.

(Orion, Emerson, Memorex, Sansui, Sylvania and Zenith). 

Possible my new tv is newer than my DirecTV box, and it doesn't have the number??

I need the remote code.

I find no additional info. on the Insignia site.

Thanks,

Diane
