Apparently the ballast fan is a fairly common failure part. You should be able to replace it yourself. It is part number 23587527 at a cost of $36.95 and can be obtained from tritronicsinc.com
Good luck.

If the set is working many years perhaps fan shaft sleeves are worn. In this case i think it is better to replace it instead to attempt fixing it.It can continue operate without problem except the produced noise.
There is a possibility that this noise could be what is called a color wheel. a color wheel is much mor difficutl to replace than a fan does it have a whinning noise when yo9u turn it on
Sounds like the unit is running hot, making the fan run constantly....there is most likely something else involved..you have a warranty on this unit?
well..it's cooler at night, no doubt, so I'm not surprised it's better then. You do have a potential issue here with some part of your internal workings starting to fail, and running hot, hence the fan issue.
Do you feel inclined to try to do this one yourself, or are you in the market for a repair person(check the repair listings here at Fixya).
wellSteve, what's it going to be? Surgery or sit back and watch an expert do it? My recommend..don't mess with this one.
and thankya for using fixya

When the TV is "off", we don't hear the fan running.
Unfortunately, no warranty.
It's 2 1/2 years old.
We unplug the TV 2-3 times waiting a few minutes each time. It's a pain doing it, but it works.
It works great all night, with NO fan noise.
You have a point.
I am not sure if it is the color wheel or fan noise.
Unplugging the TV 2-3 times seems to work
I am very reluctant to fix the problem myself.
