Hello
This is a common sign that the color wheel is beginning to go bad
The color wheel, which costs around $180, requires some expertise in replacing and thus can set you back several hundred dollars for the cost of a technician. Newer color wheels are made with an air cushion as opposed to bearings and are expected to last much longer than their predecessors.
However you can decide to fix it yourself just follow these steps;
Put on the anti-static grounding strap to keep static electricity from damaging the internal components of the TV. Turn the TV around so that the back is facing you. Make sure the TV is unplugged from the AC socket.
Use the Phillips screwdriver to remove all of the screws from the back panel. Put the screws aside. Pull off the back panel.
Loosen the two screws from each side of the projection bulb's case. Pull the projection bulb out. Put the projection bulb aside. Use the Phillips screwdriver to remove the two screws from the left side panel. Pull the side panel and the circuit board attached to it out carefully and put it down so that the cables attached to it have not been pulled out.
Take a picture of the power cable's position with a digital camera so that you can put it back correctly later. Pull the power cable out from inside of the case so that the center panel is free to be pulled out. Remove the two large headed screws from the center panel with the Phillips screwdriver. Remove the top two screws holding the panel to the plastic case using the Phillips screwdriver.
Slowly slide the center unit out a few inches. Take a picture of the projector lens' positioning with the digital camera so that you can put it back correctly later. Unplug the two cables from the left side of the center panel. Unscrew the sensor switch using the Phillips screwdriver. Slide the center panel completely out of the unit and put it down on a clean cloth. Blow off the color wheel assembly with compressed air.
Use the tweezers to remove the green plug from the top of the color wheel cover. Use the tweezers to remove the two cables at the side that are coming from the color wheel. Use the Phillips jeweler's screwdriver to remove the screws from the top, front and back of the color wheel cover. Slide the color wheel cover straight up to expose the color wheel.
Use the Phillips screwdriver to remove the three screws holding the color wheel to the color wheel assembly. Lift the color wheel up and out of the color wheel assembly and discard it.
Position the replacement color wheel in the color wheel assembly. Reassemble the color wheel and reassemble the color wheel assembly. Put the color wheel assembly back into position in the rear of the TV. Reassemble the TV. Plug the TV back in for power. Turn the TV on and enjoy seeing the colors displayed properly again now that you have replaced the color wheel.
