Thanks for the info. TV model number will help to get related manual for troubleshooting purpose.Do you get any trouble with TV like delayed power up or picture quality issue due to that high pitch sound?

No nothing at all
Expert:  Shahid replied 2 years ago.
OK, it seems high pitch sound is coming out due to failing capacitors on power supply board as switching regulator chips work on high frequency, either replace bad capacitors or entire power supply board will help to resolve the issue.Please note that above reply is generic as I still don't know your TV model number. I trust my input will help you out. Please feel free to respond if you have any additional questions.A positive rating to answer would be greatly appreciated, please click on smiley face/star on this page then click submit/finish button so I can get credit on website for my work.
