Re: continuous low whistling or thin buzzing noise
The high pitched sound is an indication that theres a short most likly in the Hi voltage sweep section or power supply and with out the proper training you should not even take off the back as there are no user replaceable parts inside of these sets. All the parts are soldered in and you can not look at them and see that they are bad.. its almost like when your check engine light comes on you look but what do you see without a computer to read the on board computer vto see what the problem(s) are. Take the set into or call a pro to assist you with this repair. good luck

Dec 30, 2008 - In my case, the monitor was fine for the first two months. But then started making a buzzing noise... 1) when on, 2) worse when .... my Samsung TV ismaking high pitched noises even if its turned off. I will NEVER EVER EVER ...
Is it 3 sets of 2 buzzes about 15 seconds apart ?
---This is a bad bulb or an improperly installed replacement
or a continuous buzzing ?
----This is a Power Supply Unit going-bad or failed. The louder it gets the harder it is working....eventually it will fail. Ensure there is proper ventilation around your TV.
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.
