It's not the picture tube(especially if image was good b4 it went dead). The high pitch noise is the power supply whinning because it's shorted or overloaded. I just fixed one of these sets - replaced the horiz. o/p transistor and flyback estimate around $120.00-$160.00

High pitch noise from the flyback

You can tell to some extent what it may be by listening carefully and trying to identify the location. If you, remove the back cover of the set; stay away from danger, just listen to where it seems like the sound is coming from. If it is coming from inside the high voltage cage it is the flyback. If coming from around the main power transformer it is one of the power supply parts.

High pitch noise when tv warms up

High pitch noise is created mostly by a Coil or a transformer,is not easy finding the source if you are not familiar with this type of coil since there many sizes and shapes,the set needs to be on while trying to find wich part is doing it SO if you dont know where and how better call a Technician and you will be safe.
