Hi , I`m Jack , yet another tech.Perhaps I can help you with this problem , please send me a reply when you see this ?I would also require the tv`s full model number off the back cover please ?
specifically the prefix letters after the model number , it would look like UH.AUSWLJM , UG.AUMWLJM etc.

Hi Marlene and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, there is a partial test to confirm if the remote is working or not. With fresh batteries correctly installed, point the remote towards the lens of an active digital camera. For every press of any/all button(s) particularly the "...Right arrow...on/off power button..." on the remote, there should be a bright light that would register on the LCD screen of the camera.
No light, no infrared transmission from the remote; remote (most likely) faulty.
On the otherhand, if the remote is good, then consider a possible IR sensor hardware concern in the unit itself (least likely).
