Need Insignia TV code for my Sony Receiver... I have an Insignia 42" plasma screen TV Model

Question

I have an Insignia 42" plasma screen TV Model NS-PDP42. I also have a SONY receiver Model No. STR-K7100. It came with a Sony Remote Control Model No. RM-AAP016. I have searched everywhere to try and find the Insignia TV code to program into my Sony Remote and have had NO luck finding an answer. If anyone can help me with this problem I would be most thankful.
