Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

Check the horizontal output section circuit. It sounds that the LOT {Line Output Transformer} has damaged.

The power supply is a switching mode power supply. They work at high frequencies. Sometimes they produce harmonics that can be heard by people. The power supply may need to be replaced if it get really bad.

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

If the sound goes out completely, try hitting the mute button (to mute it) and then hit it again (to un-mute). I've found that this work-around typically gets it working, at least.

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 wonder if there is enough air circulating around your equipment?? My DVD recorder makes a sound unless I open the doors on the cabinet that contains all of my equipment. The cable company says it is a fan to cool down the units.
