Can I replace the color filter wheel assembly situated between the lamp and projection lens. The magenta filter has moved just slightly causing it to strike the mount and brake a tiny shard off of it.

Model WD-65734. Why is there no picture?


Never heard of a color wheel needing to be replaced. Both cooling fans need to be clean and turn easily. Color wheel fan needs to turn easily. If any one of these motors does not turn, the controller will cause a shut-down. The Xenon lamp uses high voltage to operate. If the power supply was damaged, the lamp won't light. The sparking on the ballast board indicates that dirt or dust may be causing the problem. Also, the clamping diodes and regulator may be defective. If possible, try replacing the lamp power board. Regards.

Loud buzzing and standby/temp and lamp light on


That kind of symptoms indicated that the color wheel is already faulty. Confirm where the buzzing sound came from, if it is in front/near the lamp assembly, then you have to replaced the color wheel to resolve the issue.

Something is moving by lamp is making noise


The color wheels are famous for needing replacement when the bearings wear out. Thats usually the only thing other than the Lamp fan that can cause noise near the lamp.

Print Quality Issue In magenta color in HP color laserjet cp3505n i hv to change cratridge but problem not resolve Pleae help us


I received a similar HP Laserjet Color Printer with same issue for repair/ maintenance a few months back.
Actually the problem is with the printer design not the magenta cartridge and it needs professional hands for servicing and cleaning. The mirrors which reflect laser beam get covered with dust and toner. hence the image is not produced properly. note that first magenta goes off, followed by yellow, then cyan and lastly black. this is because of the mirrors placement inside the printer.

Rest assure that the printer requires ONLY CLEANING OF THE MIRRORS, which are inside the printer.

Clean them yourself with dry n soft cloth (if you are familar with such tasks) or get it cleaned by any printer repair/ service professional. Please note that the mirrors, lenses and scanner assembly inside such printers is extremely complex and can get damaged very easily especially the mirrors.

Hope it would help, looking forward

Splochy green spots on screen


Colored Blotches on an LCD Projection TV are usually caused by defects or marks on filters or lenses in the light engine (or optical block) First confirm that the lamp or main lens is not discolored by removing the lamp (unplug set and let cool before removing!) and inspecting the lamp itself and the lens that it shine onto. The light engine is an expensive part ($600-$1200) to replace and requires major disassembly.

How do I change the color wheel on my samsung HL-P5663W. I have already removed the lamp and loosened screws for the lamp housing. Doesn't seem to want to come apart. Am I on the right track?


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.

Magenta diagonal grid appearing on the upper part of the screen projected


Hello,

I think you have shifted the lenses from the original position. this problem comes when you reinstall the lens/Color filters after service. if it is the same then check the positioning of lens/filters again.
