I had the same problem on my hd52w59 hdtv and sucessfully fixed it yesterday from an answer i found here...so hopefully im paying it forward.
First off, im no TV tech so you do this at your own risk!!! Based on the research ive done regarding this subject, if there is no issue with the picture and its not related to speakers(ie. if you mute it and it still makes the sound) then its the horizontal drive coil. The fix i read was to put nail polish or hot glue around the coil. Well i came up with something easier and its worked for a few days now(fingers crossed). An old fashioned wooden clothes pin. Put it on the horizontal drive coil and it absorbs the harmonic frequency(high pitch noise). I realize this is a wooden object on a electrical piece that heats up but i have had no issue as of yet.
Now, how to locate the noisy horizontal drive coil...unplug TV from power, remove the lower rear panel around where the wires go into the tv. There are about 8 #20 torx bit screws you remove, then use a flathead screwdriver to pop one clip on each side and 3 underneath, this will allow the plastic trim panel to pop off. Get a flashlight aimed in there so you can see the components. Plug the TV back in and turn it on...wait for the noise. Now make sure you dont touch anything high voltage and once again you do this at your own risk...but take a small wooden stick (i used the stick from a plunger) and touch it to the suspected culprit...when you touch the noisy drive coil the noise will immediately go away. Once you know which one it is turn the TV off, unplug it, and put a wooden clothes pin on it. Plug the TV back up, turn it on and ensure the sound doesnt come back before putting everything back together.
Beats the hell outta paying a technician $75-100 plus parts, huh?
By the way, i posted 2 pics but they must not have uploaded or were too big. Im new to this site but if theres a way to email or message me send me your email and ill send the pics over. Good luck!
