Son gave me a 50in TV but no remote, and I can't get my extra remote to connect to the TV. So I don't know what to do
We're assuming it's a Roku TV.
You have three options for a remote. Two take a while and one can possibly be done today.
Go with option 2 if you can. You can often check the Websites of the respective retailers and search local stores for in-stock availability.
EDIT: Option 4 is listed in the following post.

One more option for a Roku TV:
The TV manufacturer supplies the original direct line-of-sight infrared (IR) remote with the TV. You may be able to find a Roku TV remote at a local store - Wal-Mart, Target, etc. Be SURE it is for Roku TV, as they use a different IR command set than the separate Roku devices do.
Roku TVs from these manufacturers all respond to the same set of IR (infrared) commands and so can be used with remotes for any Roku TV in this group:
Element, Haier, Hitachi, Insignia, JVC, Magnavox, onn, Philips, RCA, Sanyo, TCL, Westinghouse.
Remotes from HiSense and Sharp can only be used with HiSense and Sharp Roku TVs because they issue a different set of IR commands. Roku TVs from HiSense and Sharp themselves, though, support both sets of IR commands so they also be used with remotes from either of these two groups of manufactures.
