I have a toshiba 50hm67 the picture is prefect dont think the build is bad, but i have a humming coming out of the tv what could that be and how can i fix it.


If it is a high pitched or even fan like sound it may be the color wheel in that set which if I remember is not sold except with a complete light engine, do some research on that model for color wheel.

Loud humming coming fromthr rear of Toshiba DLP 46HMX85. Humming is not connected to the volume control and sounds like a power supply transformer or a fan.Changes pitch momentarily when certian functions...


YOU are describing a color wheel, in this model it may or may not be available as a part; some of these sets it is only sold with the light engine.

See attached photo of a typical color wheel.

In DLP type sets the wheel turns at up to 12,000 rpm and if bearings in the tiny motor fail it sounds like a fan or even a grinding sound.

Let me know if you have questions.

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 noise


This is definitely the color wheel. It is not the same thing as the cooling fans. The color wheel is buried; even if you took the back off the set you cannot even see it. It's a pretty pricey repair.

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
