Question about Toshiba 62HM95 62" HDTV
Behind my projector is a annoying sound. At 1st I thought it was the cooling fan.. The noise comes from the bulb that is being kept cool by the fan. The noise is more like a humming sound. When the projector is turned on after bout a min. or so this humming noise begins to kick in. When it is turned off Still! this humming sound wont stop till the projector is unplugged. I appreciate if anyone could give some type of solution.
I am wondering if this sound might be your color wheel spinning. The color wheel often makes a low humming noise as it spins. Try checking to see if this is not the source of your noise. You need the color wheel to generate the colors needed to turn the B&W picture generated by the DLP into a color picture.

Yes, the problem is the color wheel. Those are not sold by toshiba alone. You have to buy the light engine from them (a lot of $$$)
I found color wheel for sale on eBay. Just type "toshiba color wheel and you will see them there. They are little wider then the original buy fit perfect and seem to last much longer too.

I am having the same problem. I am getting a screaching noise (bad bearings) coming from some spinning part in the TV. I too took the back of, used pressured air to blow out any dust off the fan closes to the light...but it seems to be fin and is not the source of the noice. I have a feeling it is the color wheel but I am unsure on how to determine this. I will try changing the color to B&W to see if this will help identify the problem. Is it possible to only replace the color wheel if this is the problem or do I have to replace the entire light engine?
