I don't know if you can help me or not but I tried the codes I saw listed for the RCA tv and my granfathers tv still doesn't respond to this remote. He doesn't have the manual or anything. I could really use a number if someone had it. I think I followed the instructions some else gave but not sure why no of the codes work. I'm using 4 digits. Also, I don't see a search button on his remote. help
