Hi Charlie! Samsung TVs such as the 50TU7000 feature the One Remote allowing the TV remote to control all of your devices. If you would like to use a separate universal remote to control the TV, consult the user manual of the remote to find the compatible codes for your remote. If you need additional assistance with the connection process, please contact us at:
― Phone: 1-800-SAMSUNG / Available 8 AM - 9 PM EST, Mon - Fri
― LiveChat or Email: https://www.samsung.com/us/support/#contact_us_for_support
We look forward to hearing from you.
