How do I open up this set to access the color wheel. Some folks said they could clean the wheel through the lamp housing but there's glass over the small port into the color wheel. I don't understand how I can vacuum the wheel when I can't get to it. Any help would be appreciated. Thank you!
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.
To Carlos MDO, I was ready to buy a new TV when I find your instructions. I was able to clean up the color wheel and my TV is working as new right now. Thank you for detailed instructions.
My color wheel hums like a noisy fan. I can see and feel this with the TV gutted as you described above. Does anyone supply just the color wheel motor as a service part not attached to the color engine?
Thanks,
Jeff

I have the same tv with the same issue... how do you remove the wheel and is it serviceable(bearings etc...)
I have a 46hm95 and was told the color wheel was sealed but wanted to see for my self. I was able to remove the color wheel with no problems. The part number on it is OC-CW 6AB-BC016. It is a 7 segment wheel if anyone knows where to get one please let me know.
You have to remove the light engine to get at the color wheel. It is not that hard to do if you have some electronics background I would suggest you download the services manual it cost about 10 bucks..I have not been able to find a replacement for mine if anyone finds one please let me know. Thanks

You can find the color wheel from eBay. Just type "Toshiba Color Wheel"
You can order the motor from TSM. It looks like you have to use the wheel it self. I will find out as soon as mine arrives.
Toshiba colorwheel are sealed in the light engine. there is no access to it on this model. Is there a problem with the set?

Well, I keep hearing about how folks opened up the light bulb housing and vacuumed the color wheel--on this model. I was just wondering how they did this.
Specifically this post by 24fanny:
"Well folks I had some issues with the tv (46hm95) as well. Oranges and reds seemed to blur and become almost "blocky" or looked like large pixels. Facials seemed way off especially if someone had blotchy skin. I took out my bulb and shone a light into the color wheel assembly. Much to my dismay I saw that the color wheel was coated with a thick layer of caked on dust. I took the tv all apart (this was a project) and cleaned the color wheel with a qtip and windex. I aslo cleaned the projection lens which had accumulated dust. I got it back together and the tv is like new. I was missing out on so much color and detail, as the dust built up gradually over time I never noticed how bad it had gotten. I had also had some cloudy spots on the screen before this and it remedied that as well. I would highly recommend doing this to get the performance out of the tv, but if you are not mechanically inclined be very careful."
