I turned on the TV last night and the sound does not work. On prior occasions when the TV has been turned on, the picture is only a horizontal line across the center of the screen. After either leaving it off for a while or turning it on and off several times -- it usually corrects itself. Now with this latest sound problem, do I have to break down and buy another TV or is this something I can fix myself relatively inexpensively?
