I'm having mixed luck trying to program my 49TXi learning remote with keys from my Samsung HLN617W DLP TV. I’ve been able to program the volume and channel keys for the TV Control button. I am now trying to program all of the keys on the TV button. For example, I’m now trying to program the “channel +” button which I had previously programmed on the TV Control page but continue to get the NG (no good) code. I have tried moving the Samsung remote control various distances and angles with no luck. I have programmed another remote’s code to the same key with success which seems to indicate there is additional capacity in the remote to learn more codes. I’ve only programmed (learned) about 15 codes so far. My biggest frustration is that the remote can learn the codes – just not with any degree of consistency. Does anyone have any suggestions to help my 49TXi remote consistently learn the Samsung codes?
