The high-pitch squeal is from the power supply, caused by a short circuit. The usual cause is a shorted horizontal output transistor. I believe this model uses a 2SD1556, but I'm not certain. I don't have the service manual for this model, but that part is used in several other 32- and 36-inch models.
While the horizontal output can fail on its own, it's usually because of other problems. A large-tube TV like this is hard to work on, and you might want to let a professional technician check it and give an estimate for the repair.
