Orion tv

Question

My mother needs to be able to set the closed caption setting and cannot with the cable remote.
We have lost the original remote due to using only cable.
We have not needed the closed caption setting. We gave the tv to her and the tv is working great. We bought a universal remote and the list of tv compatible with the remote orion was listed. Once the package was opened and we noticed we could not use the menu setting.........we found the instructions told us we could not use that setting...........
please help my mom cannot afford a new tv......she needs this one for her bedroom.
Could we get another tv remote for the orion tv?

Thank you for your help.
