The TV has worked like charm since 1989. Today I turned it on and this
high pitched scream came out of the right speaker. I unplugged all
input and output cords and turned it on again and the sound is still
there. The volume does not turn it down, and switching the TV input
button doesn't change the sound either. The scream is really loud and
high pitched. Any idea what happened, and is this easy to fix or do I
need to trash the TV?
Thanks
