Check the transmission fluid level and condition. If the fluid level is off, correct it and then see what happens with the noise. If the fluid is discolored you should change the fluid and filter as a plugged filter can cause a noise.

I have a maytag dryer that sometimes when I hit the start button will start and run for only a few minutes and stop and wont start again for a while and does a humming noise when it does star why?


Sounds like the motor is going into thermal overload (Getting hot) it may be caused by the motor itself, or could be overloaded by bearings or fan etc

Vacume out where the fan is in the back of the tv. That should release alot of the built up dust. I try to do that to my tv atleast once a month. Hope this helps.

White Westinghouse flat screenTV freezes up and hums.


Sometimes if you just press on your overscan button on the remote and make the picture a little bigger or smaller the humming noise and freezing of the picture will actually stop.

Hi, your color wheel needs to be replaced, the bearings fail causing the grinding noise, the new ones use "air bearings" so they are supposed to last much longer, video-tek

Zenith C27V22 27" TV loud humming noise


There is a coil in the set with a magnet glued to it, called the horizontal linearity coil. Sometimes the coil "sings", making a squeeling sound. I have seen this many times, and there really isnt anything actually electrically wrong with the set. To stop the squeeling the coil should be replaced.
