Samsung HCN discretes?

I just bought a Samsung HCN4226 RPTV this past week and thought that it had discrete IR codes for power and input selection. I also have a MX-700 remote control and it has the HCN4226 in its library which shows the discretes. After setting up the remote control everything works except for the discrete codes. I have been looking elsewhere and have not yet found discrete codes that work for this TV. Does anyone else who has a HCN model have discretes that they have been able to get to work, and if so can you please direct me to them. Thanks.
