How can I get a universal remote to work with it?

Select a universal remote control at random and use its code search (or equivalent) feature to find something that will handle some or all functions of your Emerson TV. If a search through all codes stored in the remote fails, you may have to try a different universal remote. All universal remotes do not store all possible codes.
