Its so high pitched that some people can barely hear it, but I guess I have sensitive hearing. ... Anyway, this seems to be a fairly common issue and it is caused by either the ... You're probably hearing a transformer humming.

if its a high pitched squeek its a short in the deflection circuit, a common failure part here was the high voltage transformer.

Problem is in High voltage circuit and likely either the high voltage transformer or a connection right under or around it.

Sounds like the flyback # 270125 you can get a replacement at www.tvrepairworld.com which includes the CD with instructions and the two associated Capacitors.

Sounds like a coil is vibrating or a component is bad causing the transformer to whine. Could possibly just need soldering.

is this just a whine since you describe no problem with the picture it dosent jump or change color or flicker. there may be an easy fix this sounds like some coils oscillating and i tell you what can be done you can take some silcon and put on these coils to dampen then vibrations. now ther may be other problems but without looking this is my first gues ...where are these coils? ll037 on the power supply deflection board

Sounds like trouble in the standby/power up circuit. have you tried unplugging the TV for a half hour and seeing what happens? It might start up but I think this problem won't go away. If you heard a high pitched buzzing it sounds like a problem in the high voltage not letting the start up circuit work. threy are related. The start up circuit waits for the high voltage to stablize and then switches it on.

try reset.

I have a very high pitched sound and when I move the tv it will stop for a second or two and then start again. The sound sometimes stops all together. But very high pitch sound.

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!
