I believe you may be referring to a Prism TV if so, then the code that will allow you to program your DISH Network remote to your Prism TV is, 676.
I have cox cable and the prismo hd used Mitsubishi code 0178 I found this out with my harmony 300 remote as there is not a listed code and it came the closest.
I too have the prizmo hd+ flat screen, and yes the mitsu code 0178 works perfectly find. Remote is now programmed.
