The color wheel is not behind the screen, it in the optical engine. Most likely thats your issue.

Let us say you cannot wait for the lamp to go down in price $25-$50 a piece.
Put it in your driveway and draw a little circle on the center of the screen. Call some kids stand 20 feet away and exercise with a toy gun of their choosing.
When it 's all done, I mean completely obliterated, gone, gone, gone; then drag it to the curb and let it wait with satisfaction for the garbage truck.
That is what you do with **** like this Toshiba, Sony, Panasonic and others create so you can sleep at night with their hands in your pockets.
I just can't believe than I wasted $2,500 on this thing.
It's unbelievable how people stop thinking nowadays. I just bought my first and last big screen.

SOURCE: How to Access Color Wheel on Toshiba 46HM95

I bought a used 46hm95 but it had a greenish "band" that streched from the upper right corner to the lower left corner. It was only noticeable on a white or light colored background, which is why I overlooked it when I tested out the TV.

I took out the bulb and shined a flashlight into the color wheel. I could see a fingerprint smudge on it. I took off the lower rear plastic panel. the rear is split into two section (the light engine is on the right. You'll have to unscrew a metal guard (three scerws), then disconnect the wires coming from the left section, and then unscrew the plastic guard that protects the lens. Then unscrew the light engine (two screws) and slide it out carefully (you don't have to take it completely out, just far enough to reach the screws to the color wheel covers). There are two covers protecting the color wheel, one plastic and one metal. Unscrew the plastic cover first than the four screws to the metal cover. I left the color wheel in place while I cleaned it with a microfiber cloth. I did pull the glass square in front of the color wheel and wiped that down too.

I put everything back together, and now the picture is perfect.

Things to remember are:
*Keep track of the screws and where they belong, as you remove them so you'll remember where they go when it's time to put things back together.
*Mark the wire connectors from any wire you disconnect in case you forget where they go.
*Be gentle with the color wheel and the glass square because they are fragile.

Hope this helps.

Color wheel. Not replacable on this set. Removing light engine and having rebuilt is only solution. Part no longer available.

I just replaced the lamp in my tv, it will work fine for 10-15 minutes, after that the picture will start to flicker and then just go out completley and th lamp light will blink on the tv set, what could...


My 50HM66 did the same thing. Try putting a fan to the side of the tv so it blows cool air around the back. I also removed lamp and vaccuumed as best I could. I think this is an overheating issue with the tv.

Make a loud type of humming noise and the color is flickering in and out of color.


IF you are hearing a fan like noise it most likely is the color wheel that this model uses--set was first made in 2004


This model uses two different color wheels--depends on version number you will find on right side of set on a label with the model number.

The color wheel is just what it sounds like--a round plastic wheel with different colored segments that spins at about 12,000 + rpm---a lot of them fail after a few years---usually a fan like noise or grinding noise and sometimes the wheel will shatter and the set will shut down.

Once you ID the version number of your set there are sites on the internet that have video instructions for its replacement--takes less than 1 hour to do this.

If you cannot do it you will pay a fair amount as most shops like to get as much as they can for this easy repair.

LET ME KNOW IF YOU HAVE QUESTIONS

WITH THE FULL MODEL NUMBER AND VERSION NUMBER OF YOUR SET I CAN TELL YOU THE PART NUMBER FOR THE WHEEL.

I am here to help.

REGARDS, SD TECH

Missing Color.


the color wheel may spin but if you hear noise when it spins it's bad. the jumper is used when replacing one type of color wheel for a nother type. so donot remove jumper unless you've replaced the color wheel and the picture is bad. if the color wheel is good replace the DMD board. if the DMD is not available replace the optical engine.

Screen flicker


When you turn off the set listen carefully... If the noise stops abruptly it's the color wheel, if it winds down a bit after you press power off it's a bad fan..

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
