chalish, I have a TV in my house. No, I don’t put it on a timer for Shabbos.
You have the wrong idea of what MO is. It doesn’t mean you keep the basic 3 mitzvos only, and Yomim Tovim.
Most MO men daven with a minyan 3 times a day, have a seder to learn, etc. They might not wear a hat and jacket when they daven. They might have a TV in their house. They might wear a knit or leather kippah, not a velvet one.
So many people have these ideas of what Modern Orthodoxy is. Go into the YU Beis Medrash at night, and see what Moder Orthodox Judaism is about.
