Usually after watching the TV for a while, all of a sudden the TV will
give out a large audio whine, and then nothing out of the speakers but
noise, kind of like the cable has gone out. The noise is variable with
the volume control which leads me to believe it isn't the audio amp
itself. After unplugging the TV for a while it works as normal. TV was
purchased in fall of 2000.

Any suggestions?
