PS: Another cause of burn-in is the CNN ticker-tape or station bug - the logo in the corner. If you're watching a channel with ticker-tape along the bottom all day Saturday and then switch over you've got potential problems. The 12 channels of programming that I broadcast have the bug in the exact same place and we're getting complaints from our well armed customers (US Military) that their sets are burning the bug in. We're putting in a new system which will cause the bug to move a bit in a circle every hour to reduce the burn-in complaints.
