Heh, I know what that's all about. That's what makes LCD's so nice, you can bring a cheap one on cruise and not have to worry about bringing it back when you get to home port. The 13" color sets we had in our shop (I'm an AE1) were always garbage, no matter where the ship went- had one of those degaussing lines running right through the place!
Bad thing is once the screen is damaged by the ship, there's nothing the internal degausser can do about it. Maybe it's too weak, but it seems to me most of the sets that were on deployment had permanently bent shadow masks. Oh well, the CRT's days are numbered anyhow.
