try this: tell him to buy the TV and set it up when she isn't around.

when she sees how fucking amazing a 4k tv looks vs. the old one, she'll love it. 

trust me on this one. 

my mom clung to her tube tv forever. i think she was the last person in chicago to own a tube tv. 

we threw in and bought her a huge 4k tv for her birthday. my sister took mom out to brunch, and we sneaked in and set up the thing.

mom was like "oh no, you didn't!!! :(  "

we switched it on, and she was like OH....MY....GODDD!!!!!  :D

trust me.

Or she gets insanely mad that they disposed of her old tv without her knowing. From what I can read OP doesn't want to risk a potential conflict like this
