If your remote thinks it received a code but you didn't sent one then most likely there is another I/R source in the room. Is there a plasma or LCD operating in the room you are working in? Alarm sensor? direct sunlight? fluro lamp bulbs? etc, etc.
I guarantee I'll tell you the truth and I guarantee I'll tell you what you need to know but I can't guarantee that I'll be telling you anything you want to hear.
