I have a 13" Emerson TC 1351, but not the original remote. I purchased a RadioShack "2in1 Ultra-Slim" (model no. 15-2148), but none of the codes for the remote operate the TV. Even the Code Search mode will not yeild a code to operate the set. I have tried ALL of the codes listed the brand and the search mode. I can not get the set to work for the life of me. Should I get a different brand of remote or what?
