Had the same experience with a Sony 28" tube TV. The pitch of the "squeal" was intolerable. It was still under warranty so they sent out a tech. When he opened it up, he showed me a "coil" that looked like a compressed spring. He had an insulated screw driver that he used to touch it. The squeal would completely stop when the coil was touched. He shut the TV off, loaded the coil with silicone and told me not to run the tv for 8 to 10 hours. (To let the silicone cure) The set hasn't made a peep since.
