To check on the remote side, take the remote and point it at your phone camera. While using your camera app, any button you press should cause the IR to light up on the camera capture.
No light means the remote's batteries or the remote itself is dead. If using the stock batteries, swap for fresh.
My apologies. My body failed me for a few days. I looked into this more and some people say some universal remotes dont work with the TV even if it says it should (Walmart). What is the brand? I hope you have this working already though.

Could it be an issue with the IR sensor?
I've looked through the manual, and I cannot locate it on the model for sure.

Whats the next step?
They don't even expect the remote back.
