Innovage Jumbo universal remote

My mother-in-law has a walmart brand ILO tv she just bought.  She cannot see very well so my bright idea was to buy her this remote.  I can't get it programmed to the walmart tv.

Do you have a code or codes that I can try?  I am sure I am not the only one who is trying to do this with a walmart tv.

OR if you can't help with the code, do you know how to get ahold of someone at the company?

I have the booklet and have tried many of the codes but not all of them.
