Lee recently bought a Vizio 55" TV. However, frequently when he turns the TV off, it will either stay on or turn back on again. Leo says the TV probably senses the signal loss and then just stays on. It's perfectly normal and Leo suggests going into the TV menu settings to make sure it's set to turn off when the cable box goes off.
Additionally, Lee wants to know if he can replace the subwoofer in a Polk speaker with a third party? Leo says that it's possible to use a third party, but he'll lose quality as Polk speakers are balanced. He'll really want to use the same, matching subwoofer. Probably better to look for a used speaker for parts and replace it that way.
