My picture is foggy is there coolant that needs to be replaced in a toshiba 44nhm84

This type of TV doesn't use coolant. I would suggest to clean the mirror that reflects the image from the optical engine to the screen before replacing the lamp.
Let me know if you need further assistance.

I have a 44 inch 44nhm84 DLP. When the TV is turned on, it makes a loud humming noise that goes down in intesity twice and then finally a lesser humming noise after the picture comes on. At first I thought...

This does sound like a color wheel. To my knowlege, Toshiba does not sell the Color Wheel seporately. In short, you have to replace the Opical Block. The cost of this is very exspensive and Toshiba may not sell it to you. You may have to go through a Toshiba Service facility to obtain it. Check prices of new LCD sets before investing the money.
Hope this helps,

Shadow down right side of screen on a toshiba 44NHM84 44" DLP television

shadows at the bottom of the screen sound like moisture that was "wicked up" between the screen layers and dryed out leaving a stain. DO NOT get these screens wet, use nothing but a damp soft cloth; just a few drops of water running down the screen can cause a fairly large stain. Some people have suggested that they may be professionally cleaned, but the risk of damage is too great on the user level.
