I also have the Samsung UN55B8500. I am using an MX-800 IR/RF universal remote. The TV responds to IR, but the TV remote is RF only, so no learning is possible. I have found most of the IR codes I need through (1) learning from another Samsung IR remote I have for another TV and (2) from other posts on this forum. Thanks to all who post, by the way.

However, I am missing the codes for the color buttons: Red, Green, Blue and Yellow, I believe (the remote is not with me now). If anyone has the hex codes for these buttons, please post them in this thread.

Thanks in advance.
