Hello there!
Sometimes High pitching its just that, static on the area, like if you are near a microwave, or near other electronic equipments, but, if the skreetching sound keep going or even if you do nothing it could be a line inside the sound card, or you need to clean the volume botton with special electrical cleaner. other that these, its contacts, or bad cap for the volume board inside.
Good Luck!

It is probably the water passing through some restriction such as a valve or maybe a T or 90. If this is correct changing the water flow will change the pitch and it will be absent when there is no water flow.

If that doesn't change or eliminate the high pitch sound I do not have a clue.

the horizonal output transistor is shorted-replace it also resolder coil near transistor-if output shorts again flyback transformer is bad

it could be either the coils on the yoke of the tube or the flyback. flyback would need to be replaced it that is the problem

it is the fuel pump this is normal

I have the same problem...did you ever get your high pitched sound fixed?

I think its the flyback and its starting to leak. this is a component responsible for the high voltage of your tv set. always observe safety in dealing with this. Have it check by a qualified technician. Good luck!
