SOURCE: Hi pitch squeel (Electricial Hi frequency noise),

Check your power supply board for some bad caps (capacitors) on the board. They will look bulged on the top an may be a little leaky (brownish stain). A bad cap can sometimes produce a harmonic, causing issue's with the sound. Also look at the signal board (where all the inputs are), for bad caps. I have come across this on a lcd tv!! Good luck, hope this is helpful!

Hello
The LOT [Line Output Transformer] of your TV has damaged. It is the one, that supply all the voltaged needed to CRT. Its internal windings will get shorted in between, and is irreparable. Replacement is the only remedy to this proble. Replace the horizontal output transistor also with this. you haven't specified whether there is picture with your tV or not. If this high frequency sound is along with picture, there is some loose in the cores of the SMPS transformer, or LOT itsef. If there is no picture at all, and this high frequency sound is there, no doubt; LOT is damaged. OK.

try walking around the room/house and turning any other electronics off, if the interference stops, then you've found the offender! could be RFI (radio frequency interference), could also be a neighbor! if you can change frequencies on your phone, try a different one. may work.perhaps you have a computer or other electronic device that's badly shielded. you may have to replace your phone with one that operates on a different frequency, if you can't find the problem!
good luck!
