Thanks again, I tried what you said, with the exception of the battery, unfortunately my remote uses CR2025 batteries which I don't have right now to spare, and no luck :( that's weird because I was using my Harmony Hub to control my subwoofer with no problems.

Just an update regarding my Samsung tv, I had to set the repeat to 2 instead of 1 because when I had it set up to 1, I was missing some keypresses.
