Some of the larger TV's are DISH ready, meaning that they have the tuner inside for SAT TV. The SAT tuners often have an internal fan that makes a humming noise. If it sounds like something other than that, you might have a bad component in your sound circuit that allows 60 HZ hum through the speakers.


If it is a rear projection LCG TV it has a fan in it to cool the bulb. You will hear the fan if you listen closely. It usually cannot be heard over the volume.


The fluorescent bulb and electronics inside make humming sound naturally. Kinda like when you turn on a lamp, and some lamps make a low humming sound.

It's likely your color wheel rather then your fan. I've replaced quite a few of these and the fans are usually good. Get and estimate - I generally charge $250-350 Total
also google your model # and color wheel to investigate further.

DLP TV humming noise


Yes of course, it seems that you might have an issue with your color wheel, since it's a Samsung Tv I recommend that before purchasing it you identify if you have the one with either a gold or silver bearing, because if ou buy the wrong one it won't work on your tv

TV Just Started Making a Humming/Buzzing sound


Replacing a flyback is not something I would suggest for anyone with no electronics experience. Second, lets see where the noise is coming from first. Take off the back and listen to the noise. The flyback will be at one end of the large red wires that go to the tubes. Sometimes the connection at the tube is not 100% and the noise comes from there. BE CAREFUL - there are high voltages going through this red wire that can be dangerous even with the set UNPLUGGED!! IF the noise is coming from the connection at the tube, with the set unplugged, carefully turn the rubber cap back and forth touching only the rubber part with one hand. Put the other hand in you pocket while doing this.

If the noise comes from the flyback side, if you can solder, again with the set unplugged, try resoldering the pins on the transformers. That may resolve the problem.

Keep me posted.
