I shot mine. (On purpose, on the range ... but still the most fun shot I've ever taken. I'm easy to please, I guess. Giggled for days.)
The real question is, is there
any possibility of someone getting between the gun & the safe backstop? If your TV is against the back wall (rather than a room or two away from the back wall), and the back wall is built right up against the hill, and/or your backyard is not merely fenced off but locked against people going out there while you're dryfiring (and you know your wife isn't out there weeding the roses) -- then go for it.
All common sense, really. The deal with the backstop is, it has to be something that stops a bullet
before it can strike something else. The TV itself doesn't count, but the dirt hill behind the house certainly would. If there's a TV between you & the dirt, no biggie. But if there's any possibility of a person getting between gun & backstop, there's a problem.

Oh, and good luck with the crusade/plot to get a new TV.
