I had been watching a ballgame(well actually a ballgame and a movie on TCM) for almost an hour.I turned to look at my cat Harlech (a castle in Wales) for just a second and when I looked at back the picture had shrunk to the center of the screen and turned a funny brown color. Just as I thought--- what the--- a funny cracking sound came from the rear of the set followed by a loud POP and a strong electrical burning smell. "This does not look good" I thought. Odd that I had been thinking earlier that we have had this set for 20 years . And it still has such a great picture! Talk about going out with a bang!
