Using a circular motion, swab gently one color area at a time Use dry swab to remove film build up. Repeat to ensure the wheel is thoroughly cleaned DLP color wheels need to be cleaned approximately every six months to a year, if the environment they are placed in is smokey, greasy or dusty. Sometimes, restaurant owners or places with high customer traffic will find that their TVs are experiencing picture degradation due to the smoke-filled rooms or greasy fumes from kitchens. There is no need to replace the color wheel but just to do a quick cleaning to save money on replacement parts. Even if you have your TV at home, your DLP color wheel may require a cleaning occasionally to provide clean picture quality.
Thats your Color wheel But acorrding to what I researched you have to Replace the whole optical Module part# 9NK3797086200 which is optical module,light Engine & Colorwheel Encompass Parts do not have it in stock but they List its Price $1,930.00 core refund $1,030.00 cost of total replacement is $900.00 you can call them to find out 1-800-638-3328 or try UED 1-800-648-6657. See if you can just replace The Color Wheel itself because that is what is Bad! OR are you better off to just replace the whole unit!
When the Color Wheel Motor does not turn any more the set will shut down. The only way to my knowledge to fix it if this is what is happening is to replace the Optical Block. It consist of the Color Wheel and Optical Path as one unit and it is expensive. I estimate 700.00 to 800.00 maybe more. You could try to price it through Encompass Elect. 1800-638-3328.
Hope this helps,
I have a Sharp 56dr650. The color wheel bearing failed. Sharp cares not for its customers and won't even respond to my pleads for help in obtaining the replacement. So, with that said, I went to ebay and bought a vizio color wheel (Omega TV in Hollywood, FL). Color wheel is incorrect and colors are all blue as is, so I pulled the color wheel off and did the same from the old one-BIG note, the wheels are glass and fragile, DO NOT BREAK the old color wheel! I viced the old bearing and carefully worked the shaft out of the bearing (it is snapped into the bearing). The vice distorted the old bearing but it was trash anyway. The new bearing, I broke the new color wheel off and viced the shaft. I then pulled the old bearing from the wheel. I then carefully push the old shaft and color wheel into the new bearing (you will know when it snaps in place) asserting preasure ONLY on the metal center hub with my thumb. I had to file a new slot on the cast housing as the ribbon connector is about 1/2 inch shorter on the new bearing. I installed and it all works great!!! Saved from tossing a $2,000 plus tv out! SHAME ON SHARP! Never buy another Sharp product!
These set have a problem with the color wheel, when it starts to fail it will do what you describe. The bad news is Sharp will not sell just the colorwheel, the sell the entire light engine for $1200.00 ond as of today I still have not found a replacment colorwheel that will work for this set
i have a 56DR650 and it does them same thing. It is still under warranty but where i bought it, they said they can no longer fix it so they are giving my money back. the problem has to do with the color wheel inside.
