Samsung DLP HLN507W color wheel sensor

Hello, my color wheel has been acting up, it doesnt always start when I power the TV up, I noticed the wires from the sensor module were fried badly, brittle etc, I suspect the sensor and wheel may have been damaged, at least I am hoping its not the DMD module

I replaced the sensor wires and stuck the wheel assembly in the freezer a few times, and it started about 6 times before it stopped agian on one attempt, the wheel itself sounds ok when it runs, it has 4 and 8 ohms across the ribbon cable at different spots so I am focusing on the sensor now

Those two square components on the sensor board what are those led diodes? does anyone know what they are maybe diodes and if so what type and rating? I am hoping I can find a match for them if thats the trouble, I just want to get the thing to run long enough to test the DMD module and Light Engine

Any info would be appreciated Thanks

    My sensor seems to be fried as well. My tv freezes with an negative black and white image. I am hoping that the sensor is the culprit. Right now I am waiting for a phone call from samsung for they are trying to locate which sensor I am looking to replace. Is this thing easy to find at a local electronic store?

    The fact that my colorwheel didnt always start afterall was not the wheel or sensor, it was scrammed logic due to shutdowns caused by an Osram replacement lamp that was either bad or incompatible with this 5 year old set

    I think the switching power supply was also messed up from the hundreds of starting atemtps I had made trying to figure this out



    After I installed a Phillips OEM lamp it started working eventually after the logic and power supply stabilized

First of all I take it that your TV is a PS60690 model. Unplug the TV and let it sit for a few days because there is approximately 3,300 volts at the splitter. You’ll have to remove the front lower panel. It is held in by clips around the top. I removed it by hand. Once you get your fingers to pull it away a bit the clips should release and then you can just lift the piece up and out of your way. Next you will have to remove the convergence panel in the center. Remove the bolts that hold it in and un clip the four wire connectors (2 on each side) and set the panel to the side. The splitter is now visible by looking into the hole and up to the left. It is held in by 2 bolts one in the front of the splitter and one in the back of it. Don’t remove it until you have all of the wires removed. Remember to be very careful here because of the potential voltages. The voltage should bleed themselves off over time but might not! I used my electrical meter to test for voltage before I touched any bare wire. What I did was remove the wire with the red grommet that holds it up into the splitter. There are 3 green grommets and a black grommet. They might be hard to see the colors because of the dust …. Just wipe them off. The red one is the one on the far left of the wires that are 4 in a row. I used a screwdriver from the front and lightly pushed the retaining clip towards the back of the TV while gently pulling the wire downwards. Watch out for the little bushing that is around the wire. Try not to lose them because you will need them to put the splitter back together. Now I took the red lead from my tester and touched it to the exposed wire end that I just removed and touched the black lead to the metal part of the TV chassis where the splitter is actually mounted. Once you’ve established that there is no voltage present, label all of the rest of the wires so that they will be put back in the right places when you are ready. Test each wire the same way before touching them. Remember to be careful and capture all of the little bushings You will need the splitter before you do this so you will have to buy it. The RCA part number is 205064. I have to run right now but I will send you any info that you might need ……. Just ask …… I don’t mind helping out if I can. There is more.

SOURCE: adjusting color after color wheel replacement samsung dlp tv

There should be a jumper somewhere around the color wheel. I am having a problem with my color wheel, and after doing a lot of research I found that people that have the same problem as you changed the jumper setting. Try looking it up here on the net. Should solve your problem.

There is a humming in back of tv.the sound always good but picture doesnt come thru and i get a green screen someetimes blurry with distortion.color wheel or dmd chip or lamp starting to go out


as my experience, the most possible reason should be the color wheel or its photo sensor board.

firstly try to clean its photo sensor board, or have to replace a new wheel.

i just have this wheel, when you need to replace it, contact me freely

This tv have a colors wheel design in it.The tv make loud grinding motor noises or pictures flashes or freeze and pictures turn in black&white with sound.The tv colors wheel it is dying or worn out already.Don't tries to change the tv colors wheel ur self.If u don't any mechanical skills,because the colors wheel it sit way back of the tv,must take out many mechanical parts before even can come to the tv colors wheel itself to replace it.Best to hire a tv tech. to change the colors wheel,so no problems for tv funstions for later or damages more parts on the tv set,if u install the new colors wheel in the tv wrong way.

Shuts off after a few minutes


This is a common problem for samsung DLP tvs and is due to the age of the lamp.

See this article for some solutions to extend the life, but in the end, you need a new tv or a new lamp.

My samsung dlp turns on, then after 10-15 sec turns back off


It could be the temp sensor going bad. This sensor sits on top of the metal housing which the bulb assembly slides into. The bulb assembly will have a hole on top and this is where the sensor is above. There is a small blue and white wire that plugs into it. If you pull the wire out and put a paper clip or wire in the coupling you will basically bypass the sensor connecting the blue and white wire. If your tv turns on then that is your problem. Its cheap too. Here were my symptoms..1] Turn tv on 2] Bulb would light up..(which eliminates the ballast) regular picture would show up (which eliminates the bulb and color wheel) 3] 30 seconds later tv would shut down with 3 flashing lights. After bypass the tv turned on as always and hasnt shut down yet. Always un plug tv first. Get the replacement part to avoid overheating and possible fire

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.

My Samsung DLP model HL-P6163W keeps turning on and off and now lights are flashing. We replaced the color wheel last year and about two years ago the lamp.
