The warranty companies always seem to say the same thing "It may be something you have to pay for." So what does the warranty cover? Why would this be something you might pay for? Here's a suggestion that might be stupid, but what the heck: Next time the LG freezes, leave it on and call the warranty service. Don't turn your TV off, even if it's days until the person shows up. It won't damage your TV. I've had my LCD stay on for days with no adverse affect. This might be the only way to prove your point. If the TV isn't frozen when the tech shows up, then he might say "There's nothing wrong, so you have to pay for the service call."
