Locating my color wheel in a sharp xr-30x dlp prokector.

The picture on my screen has become very blotchy and it continually flickers. Reds become purple and blotchy as well as most other colors. Through some searching i have heard that i may need to clean the color wheel but i do not know how to access this. Is this the right solution, and if so how do i execute this?

    The lamp was changed in my sharp xr-30x and the lamp timer was not reset. So when it got to 5% or less it started turning off. I unplugged it and attempted to reset the lamp timer but it just said to change the bulb. Now both indicaters are red and I can not make it do any thing.

Hope this reaches you in time.

1st: Turn the projector off, but leave it plugged in.
Then do the following......
Hold down simultaniously :
Help/Menu button, Enter button, and down arrow button,

Then while holding down all 3 buttons.
Press the Standby/On button

Once the projector turns on let go of the buttons, the press Enter button again and you should see a message in bottom left corner that says "Lamp has been reset to 000000"

    To Clean Color Wheel .

    Have projector turned off. Flip upside down and remove all screws on bottom and back of projector.

    Then on the back wedge a flat head screw driver in the space between the back panel and the top panel (carefull of course) and turn screw driver a little to separate top and side panels (which are all connected) from the bottom part which is connected to the inside parts.

    Once you have the top off you will see wires and all kinds of mother boards and stuff.

    Look a the front near the lens, then to the left a bit. (PS. You should also have the bulb removed already) You should then to the left of the lens that is facing you see a metal area with a fan. Remove the fan, but don't disconnect ANY wires. Just pull the fan out and place on top of the green mother board. Then you should remove as much of the metal as possible around the fan area.

    You should then be able from the looking at the bottom up of the projector see the color wheel. It is in a secure area with a hole in the metal to let light come through.

    I myself did not see a safe way to take the color wheel out. So what I did was use a Q-tip with rubbing alcohol and place the Q-tip through the hole where the light goes and place the moist Q-tip on the color wheel. Then with my other hand I slowly turned the wheel and collected dirt on the Q-tip. Then just keep turning and using new Q-tips as necessary.

    I smoke around my projector and after 3,000 hours the picture looked like I was on acid/LSD. So I did the previous, and now the picture is like brand new again. I have over 3,800 hours on the same bulb and the picture looks great, and the projector works like a champ. Good Luck.

I would try the lamp first. if that doesn't fix it then it is definately your color wheel. you can clean the color wheel. it is very easy you just have to be careful not to break it and make sure you clean the colored lens before you install it. I took my color wheel out and took apart the motor and cleaned the hell out of it. if you do this make sure you put a thin high temp grease on the axle of the motor before you put it back together. there is an article here on this website that shows you exactly how to take the color wheel out. follow those instructions then do what i told you. i am positive it will fix your problem. Also, to anyone else reading this if your tv is making a loud noise or you changed the lamp and it still doesn't work thats because most of the time the grease inside the color wheel has dried out or you no longer have grease in there causing your color wheel motor to sieze up. its okay because it is not bad. do what was mentioned before in this article and it will most likelly fix your problem. I did it and my tv works great with no loud noise or even then loud humming noise. if you have any questions just email me. good luck

Projector Input is on DVI - Video. HDMI cable thru an adapter is plugged into DVI port. When av receiver has "TV" selected; Picture is projected. When Blu-Ray is selected; there is no picture....

The Sharp XR-30X will display 720P and 1080i. The Blu-Ray player is trying to send 1080P which requires a handshake. It sounds like you might have to go into the Blu-Ray player and tell it to use 1080i.

Sharp XR1S It projects the image on screen, use to show the correct color. last time the image was projected but in pink hues. is this an adjustment issue or is the lamp going or gone?

first of all check the tint setting on your projectors picture menu.
if not get the correct color then, your projector is a dlp projector that means it have a color wheel in side. if the synchronization of color wheel is not correct this problem can occur. there is a sensor for couting the rpm of color wheel. also have a black mark on the color wheels rotating portion. the sensor scene this black mark for making count. if there is any dust in that portion it will make difficult to the sensor making the counts. you have to remove the color wheel to clean the same.
i have added a video how to clean the color wheel . not the same projector.
