David bought a refurbished Vizio HDTV and after a few hours of using it, it started to smell. Leo says that really shouldn't happen to the degree that David smells it. His fear is that it will start smoking. Leo's advice is to never buy refurbished devices from a third party. Only buy refurbished from the manufacturer directly. The capacitors may be leaking oil and when heated, could cause the smell. If that's leaking, then it's definitely going to fail. David should try taking it back.
