Ok it could be a fan...or a colorwheel...turn the tv on....let it power all the way up...then shut down ...you are listening for WHEN the noise stops...does it stop when the lamp powers down..look @ the back to see this..if it does then it will need a colorwheel..if the noise is there for 5-10 minutes after lamp has shutdown then it is a fan...problem: there are 3-4 fans in the tv...which one is the next question...let me know what you find..

Why does my magnavox 52 inch dlp make a fairly loud humming noise for 10 minutes or so after turning the tV on? It gradually get quieter.


It is likely a bad fan that gets quiter as it warms up from use. There are two fans on that TV - one under the bulb housing and one at the left vent hole. They are special fans with three leads - +, - and an RPM indicator (yellow lead typically).

Loud humming coming fromthr rear of Toshiba DLP 46HMX85. Humming is not connected to the volume control and sounds like a power supply transformer or a fan.Changes pitch momentarily when certian functions...


YOU are describing a color wheel, in this model it may or may not be available as a part; some of these sets it is only sold with the light engine.

See attached photo of a typical color wheel.

In DLP type sets the wheel turns at up to 12,000 rpm and if bearings in the tiny motor fail it sounds like a fan or even a grinding sound.

Let me know if you have questions.

maxie99,

Fan is available at https://www.encompassparts.com/webwiz/wwiz.asp?wwizmstr=WEB.SEE&partnumber=6475656&smodel=52HM95 for about $80.00. Replacement should be as simple as unplugging the fan cord and removing a couple screws to remove. Do the work with the unit unplugged from the wall. Reverse the procedure to install the new unit.

Thanks for using FixYa and the great rating.

Our TV is making a loud humming noise. We think


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.
