Toshiba 46HM95 DLP Projection Televison One of the fans doesn't shut off isn't the bulb fan..

SOURCE: Toshiba DLP fan noise (52hmx95)
i constantly hear complaints about fan noise in dlptvs if you sit in front of your computer you will hear the same noise even in the next room there is no solution to the fan noise problem this product has a huge cage fan and a second and third three inch fans in it.... more than the samsung product it can be noticeable if the tv is on hard surfaces ie wood floors ,inthe corner, glass top etc the vents on the back of the tv allow for proper cooling of the lamp at shutoff so it doesnt shatter the tube its kinda like annealing glass its designed to extend the life of the lamp .... which im sure youve priced call toshiba and tell them your lamp is bad right now and get a new one for an emergency ( warranty if you can do it ) they are also improved this product is known to have short bulb life sometimes the zinging noise you hear is indicative of a bad color wheel in the light engine which would require replacement ( not cheap) toshiba will not piece out the color wheel assembly individually

I have just run into the same thing, prior to the picture not coming on there was a loud whining noise, I thought it was the fan in the back, but, what I tried was removing the lower back panel, LIGHTLY tapping the light wheel assembly just left of the Bulb housing, and using a shop vac to first, **** the assembly around the edges and then reversing the air and Blowing it out. After much dust and dirt flying around the TV came on. It now only makes a little noise now and then, but, I will try this again today and then put the back panel back on. Since it would probably cost as much as a new TV for the color wheel, I gave this a try. For now, it is working.

my 46HM95 was humming also, I have the extended warranty and the company came out and diagnosed it as the light engine. the part was backordered and it was just fixed today, it was ordered back in February. Problem was solved.

Since the set seems to correct itself when "cool", I would first try resoldering the convergence IC area. Quite often, the convergence problems start with poor connections that eventually cause the ICs to fail. Rather than spending money on a repair kit, try the resoldering first. I will verify the kit contents in the meantime.
Please keep us posted on your progress.
