If you need the code list for the original HP-T4254 remote, BN59-00599A, these are listed in the manual starting at page 22. The steps to program the remote are on the preceding page. Crutchfield has the manual on the product page: http://www.crutchfield.com/S-TYaga4aDv9F/p_305HPT4254/Samsung-HP-T4254.html . The direct link to the manual is http://pdf.crutchfieldonline.com/ImageBank/v20071022131600/Manuals/305/305HPT4254.PDF . Please note that the codes programmed into the remote will probably not operate devices that are newer than the TV. Sometimes electronic devices that were released less than 6 months before the remote was programmed will not respond to the available codes in the given remote. If you are trying to find a Samsung TV code that will work with another remote, please indicate which universal remote you are trying to program. (There is a Redi-Remote replacement for the BN59-00599A that does not function as a universal remote.) I hope this helps. Cindy Wells
