Question about Samsung HLP4663W 46" Rear Projection HDTV

1 Answer

About the DLP TV you helped with.

I have the DLP TV that won't turn on. Do you have an idea of what the supply voltage to the color wheel should be? I am getting around 2.5 volts from the dmd board. Does that sound about right? When I hold the door switch and try to turn the tv on I can tell the color wheel does not spin.Oh by the way the LEDs on the DMD board are lit up and there is voltage to the ballast. Do think this would confirm the color wheel is bad?
Thanks,
Brandon

Brandon. Locate CN110 on the DMD its a wire plug. Pin 2 is gorund pin 4 is voltage for the color wheel. When the color wheel is off pin 4 should have 5V on it when power is pressed it should have 7v for the color wheel to start. If the voltages on pin 4 is 5V your DM is ok and Color wheel would be indicated as faulty, But if pin 4 is anything less than 5V its the DM which is faulty.

Tv will not turn on the power light comes on then shuts off again


Hello, have you checked the lamp to see if it's broken? Next thing is was it making a whining noise before it went out? If so the color wheel could be bad. the third thing would be the ballast board, it supplies the voltage to the lamp, Let me know....tks.....Terry

Samsung DLP R&R Color wheel Model #HLR5078w


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.

Why does my samsung tv cut off by itself after 1-2 min and flash a red lamp button?


A little explanation first- this model (as do most Samsung DLP sets) will try 3 times to get the lamp lit before the microprocessor will give up and then the 3 lites on the front will blink indicating a LAMP failure. This process takes about 1 to 2 minutes. In order of probabilty, the failures are:
1) A faulty lamp and/or ballast. REPLACE LAMP AND/OR BALLAST
However, a faulty lamp and/or ballast are not the only things that will give this blink code-
2) If the color wheel has a bad bearing and turns too slow or not at all, the microprocessor WILL NOT let the lamp light, and then give a LAMP blink code. A bad color wheel will normally have some sort of abnormal sound- a low growl or high pitched whine is common. REPLACE COLOR WHEEL
3) ALSO, if the microprocessor (on the DMD board) in its color wheel rotation detection or processing fails, once again the lamp is prevented from coming on and you get a LAMP blink code. REPLACE DMD BOARD
IF THE SET EVER COMES ON WITH A PICTURE for even a fraction of a second or though it takes many tries, the lamp and ballast are good. The problem must be either the color wheel or DMD board.

No display or sound on Mitsubishi WD-52725


This is a DLP They have issues with the color wheel, the winding sound could be from this color wheel. If it stops spinning it will cause the tv to shut down. DLP is a mechanical display process. If you are handy and understand electronics you could replace this yourself. If not i would let a tech handle it.

I need help with my DLP TV


If you have verified the votages are there at the color wheel and its not spinning the color wheel is most likely defective. the sound you hear when spinning by hand is most likely the bearing but that shouldnt stop it from spinning. but as i said if the supply voltage is present but it still wont spin. the color wheel must be defective.
