You don't want to buy something like that because optical disc players tend to have much shorter life-spans than televisions. Repairs are ridiculously expensive these days and it's often cheaper to replace a component. You'd eventually end up with a TV that has a broken disc player built-in.
Best to keep your components separate. If something breaks, you can replace it instead of being stuck with a partially functioning unit.
