I looked up several posts on remote issues with Sammy tv's, but seems like I can't make RC64R work with my Samsung LN-52A650 tv. I have the remote programmed to 10702. I can turn the tv ON, but can't control the volume nor turn the tv OFF. I went thru all 20 or so codes for the sammy tv's, but none of them will turn the tv OFF nor control the volume. I am starting to think that there might be a problem with the remote (however, it control controls the HR21 perfectly, and I also have a Pioneer receiver that also works with the remote). Anybody have any ideas??
