Advertisements New Tivo User having some difficulty with the Tivo HD and my HD TV, the Samsung LN-S3251D. I have tried all of the Universal Remote codes the Tivo displayed for use, but I have never been able to get the channel up/down to work. Using the first code 0306 I have had the best results, getting Power, Volume, Mute and Input to work, but I really need the channels up/down working. I havent seen anything about my model TV online in the forums here or at AVS. Has anyone had any similar issues or solutions? Thanks for any help you all might have.
