This television has been in my 93-year-old mother-in-law's room for a long time. Deleting is no longer possible. So I googled it, took a chance and everything works. It's "universal", but don't miss the sticker. Insert batteries and change channel, adjust volume and switch to ROKU input. This is victory. The price was excellent. Well, as long as it doesn't end up on the ground, in a trash can, or in a cup of water, you're fine.
