is a whole tv screen! our wedding present TV from 1998 is slowly dying. It constantly has a fuzzy bar at the top of the screen but that's been going on for awhile and isn't too bad since you can still make out the picture everywhere else clearly and the fuzzy section isn't totally snowy so that part is still mostly visible.
However the latest development is more troubling. Occasionally, the screen goes completely black except in one central horizontal strip. Usually it goes back to normal if we power off for a few seconds but I think it's a sign that our tv isn't long for this world!
