I am a certified Crestron Programmer and have been using the version 7.7 discrete IR codes for a few years now. They were working amazingly on the Samsung UNxxxxxx model tvs.

Until I purchased the UN40H5003. The discrete power on/off command does not work on this TV, along with discrete input selection. However power toggle and source toggle does work.

After a little digging on the internet, I found some Logitech forums that have end users seeing the same exact result with this model, that their discrete commands don't work, but their toggling commands do.

I tried contacting Samsung tech support directly, and they referred me back to my 'universal remote company'. Ugh.

For those who are going to repost the mega list of the Samsung commands, I have tried every.single.one.of.them. All 250ish of them. When I try and use the discrete commands, this particular tv says "Not Available" in response to the command.

Anyone have any other info that could help me and others out?
