Just so there’s at least one voice saying it: Don’t break the TV. It’s a stupid, irresponsible and duplicitous idea.

Maybe try different ways to convince her, including the classic “I’m saving up for something I want”:

“I’m going to set aside X amount per month until I have enough to get a new TV. The one I have my eye on has (feature X) which will make (this scenario) better. I plan on selling the old one once I have enough, so someone else can get some good use out of it.”

That defuses “it’s still got life in it”, because that will make it more valuable to sell.

And then just do what you said you would.
