Question about Sharp 56DR650 56" Rear Projection HDTV
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?
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"

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
