The noise you hear must be from its back-light inverter board. The ferrite core in the inverter transformer may make a high whistling noise and will be annoying. Contact any technician. It can be stopped by gluing. But is a skilled work.

This is the Famous 3 strikes and out for RCA's--it tries to come on 3 times and if fails shutdown occurs.

The high pitched sound may be a short or could be something arcing--if the sound comes from near the very front of set--could be the HV splitter this set has arcing.

the noise is the evap fan hitting . now either its comming off the motor shaft or its hitting ice build up caused by incomplete defrost . It's time to call the repair man . as the noise will quit and the cold will too . mm

Ur high voltage is going through FBT,the big black block of plastic with a wire red or gray solder to the board.The Flyback transformer.There a steel "3 inches like a paper clip like steel.Put some supper glue on that "3 steel paper clip look like, will help or stop loud wishling noise all together.

a couple of things could make the tv chassis whistle
1 coud be dry solder joint probably on power capacitors
2 IF your tv has tube the board on the back could be making the noise its to do with the yoke on the way out!

Check flyback and horizontal output transistor.

The problem i had was when i would play my tv. I had it hooked from my dish to the sony then the tv. When i played a dvd,cd or the tuner it didn't make that noise. It seems my video/audio 2 channel was going bad. I disconnected my rca jacks and used the optical audio connection. The noise stopped and i got a better quality sound.

hope this helps

Is the buzzing coming from the back of the TV, staying loud even when the volume is turned all the way down, or is it coming from the speakers?

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.
