How do I know if the buzzing noise I am getting from my tv is the cooling fan or color wheel? Can these be changed independently of each other and can I do it myself?

The buzzing is most likely the fan. A low volume intermittent screeching (like when a small motor needs lubricant) is probably the light engine. It also may have a really wacky picture with the sound.

Toshiba model number 62HM95 62' makes grinding noise


SORRY, This is from the authorized Toshiba parts center:

"The color wheel, lamp fan, lamp fan holder are parts of the LIGHT ENGINE only." It means the wheel is not sold separately and there is not even listed in the breakdown for the set a part number.


A replacement light engine (optical light engine) retails for 456.00 list and is sold on an exchange basis only.

TV MAKES A HUMMING NOICE WHEN TV IS ON, WHEN TOUCHING THE BACK OF TV WHERE NOISE COMING FROM IT IS VERY HOT. IT WILL THEN GET LOUDER AND EVENTUALLY CUT OFF TV. TV WILL COME BACK ON AFTER IT COOLS OFF. WHAT...


It is either the color wheel or a fan. To isolate the color wheel, remove the back cover and make sure you put the lamp door back on so that the door interlock switch is activated. Turn the set on and get the picture and humming noise going. Just to left of the rear fan there are some wires. One is a really flat brown or rust colored ribbon cable that plugs in to a board on the left of the wires. This is the color wheel ribbon. When you unplug it the set will keep going for a moment or two but if the noise stops, you will know it is the color wheel. Don't be alarmed because the set shuts off with this ribbon disconnected. Just let all the fans stop (for proper cooling) and then unplug the set for 5-10 minutes. If the humming did not stop you have a bad fan motor. Plug the little ribbon back in while you have the set uplugged. Plug the set back in and turn it back on and try to isolate which fan it is, if it is a fan. If you determine it is a color wheel, the light engine will have to be replaced as Toshiba does not offer just the color wheel. If it is a fan, those can be replaced. I hope this helps. Let me know what you find and thanks for using fixya.

Constant Buzzing sound when TV is on


The wiring may have fallen back onto the fan or that may never have been the problem at all. A common problem for DLP TVs is the color wheel motor. It will hum and change pitch especially as you power the TV on or off. Its an expensive repair in this TV because Toshiba does not sell it independently from the larger, more expensive light engine assembly. Don't allow this to fall out of warranty! Call the extended warranty company and tell them that the repair was not effective and that you want this resolved promptly before the warranty expires.

Sounds like you have a bad color wheel if they tell you it's not available but only with the engine you can get just the color wheel there are vendors just for hard to get parts

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.

Thank you,

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
