Loud Humming Noise

I have a loud humming noise whenI first turn on the TV.. It lasts for about 10 minutes before eventually fading to a small buzz that the TV sound drowns out. The picture still looks fine though. Can anyone tell me what the problem could be?

    My problem is the same as mparksputts's as of the last couple of weeks.

    I slid the try out that contains the light bulb and it seemed to have less of a hum after carefully cleaning the fan behind the light after i put all back into place it still hums, but quieter. Is the fan wearing out?

    I have the same issue. But now we have no picture and only sound. The hum is still there and it seems to "rev" up and "rev" down at times. We are looking into replacing the bulb but now we are concerned that it is more than just the bulb since in july of 2008 someone with this issue posted they replaced the bulb and still have the same issue. Any suggestions? We can't afford a technician to come out and/or afford to get ripped off.

    Periodically when we turn on the tv or if it has been on for a while, it makes a very loud humming noise. We have turned it off and after a little while, the noise will stop. Happened twice today, when turning it on and then we smelled an odor, like parts may be hot or burning. Could it be the fan not spinning properly? Please help. Already replaced the bulb and the vertical hold in the past and did not have this noise either of those times.

    I have a loud humming noise that stays on the entire time the TV is on. The picture is still great but the noise is very annoying. It sounds like a fan vibrating.

Samsung is notorious for having the motor on the color wheel burn out. If the color on the tv starts to fade or shift tones when the rev'ing or noise is happening then you'll know its the color wheel. There are only two moving parts in this set, the color wheel and the fans. If you're smelling something, it could be either. Take the back off the set and put a piece of tape on the lamp door switch and turn the set on. Try to pinpoint the source of the noise. If its a fan, no big deal, Radio shack should have a replacement. If it sounds like its comming from under the set, dig a little deeper and try unhooking the color wheel motor, not as easy as I am making it sound but either way the fan is about $20 to fix and the color wheel is about $100. Sure beats a $400 tech bill. If you get stuck, comment back and I'll send pictures of the dismantle.

Buzzing/humming noise that increases as you raise volume. So loud that you can not even watch tv

Hello snow1525,

You may have a torn speaker element. This is usually the cause of buzzing noise in the sound, also you may have a bad capacitor in your audio section. This is what I would suggest doing as a test open the front bottom panel of your TV and visually inspect the speakers for signs of ripping and or tearing in the speaker element. If the element or elements are torn it may be possible to repair it with rubber cement or rubber paste just coat the tear with the rubber cement to hole the torn edges together and allow it to dry for two days before testing the sound. If the speaker elements are not ripped then the problem may be a bad capacitor either in the audio section (power supply) or in the filter block (usually attached to the speakers to separate bass and treble signal to the speakers.

I hope this helps,

Thank you,

TV makes humming noise, lamp light is blinking, does not turn on

Your color wheel needs to be changed. Mine just did the same thing. I changed mine, and the buzzing sound went away, however now my picture washes out with light or yellow colors. The darks look green and purple also.
