Samsung's digital light projection (DLP) televisions use a spinning color wheel to create the colors that are seen on the screen. If the color wheel becomes misaligned during use, it will become damaged and have to be replaced. Replacing the color wheel on a Samsung DLP television can be done at home, once a compatible-sized color wheel has been bought from a TV supply store.Replacing the color wheel yourself will void any Samsung warranty that might be in place, but is the only solution for getting the TV working again in as short a time as possible.
Put on the anti-static grounding strap to keep static electricity from damaging the internal components of the Samsung DLP TV. Turn the Samsung around so that the back is facing you. Make sure the Samsung is unplugged from the AC socket.
2 Use the Phillips screwdriver to remove all of the screws from the back panel. Put the screws aside. Pull off the back panel.
3 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.
4 Take a picture of the power cable's position with the digital camera so that you can put it back correctly later. Pull the power cable out from inside of the Samsung's 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.
5 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 Samsung and put it down on the clean cloth. Blow off the color wheel assembly with the compressed air.
6 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.
7 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.
8 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 Samsung DLP TV. Reassemble the Samsung DLP TV. Plug the Samsung DLP TV back in for power. Turn the Samsung on and enjoy seeing the colors displayed properly again now that you have replaced the color wheel.

I understand what you are saying, however the devil is in the details in reference to your problem. Let me explain, DLP Televisions use what is called "Color Wheel Technology". A wheel made up of primary and secondary colors spin at a synchronized rate with the Luminance Video signal and this along with the changing of the mirrors of the DLP processor creates the color that you see on the screen (This is a high level description, but it covers what is happening). Now what you are experiencing can happen if the sync between the signal to the color wheel and the DLP processor is off center, if the color wheel is out of alignment, or if the signal to the DLP is drifting. The bulb "light" is working but something happened to interfere with the sync between the color wheel and the DLP processor. I would suggest getting this looked at by a DLP qualified TV technician, because of the nature of this problem. In addition I would request that you have the technician do a certified alignment after the problem is taken care of.
it is the STK's in the rear that need replaced usually about 300 to do the job, call a jvc familiar reapair center, They say they always have them in stock
Your convergence amps are bad. Replacement is necessary and I would recommend contacting a servicer in your area. You can find an authorized JVC serivcer at this link http://maps.jvc.com/cAscList/
