A:Answer Hello Angel, thank you for your question! The RCA universal remote includes codes for LG TVs, so it is highly likely to work with your LG TV. However, AT&T U-verse boxes typically use RF (radio frequency) technology, which many universal remotes, including this one, do not support. If your AT&T U-verse box has an IR (infrared) mode, you may be able to program the remote to work with it.
