Question about Samsung DLP HL-P5663W 56" TV

3 Answers

I have a samsung HL-R5064W dlp tv that the lamp won't light. When I turn the tv on it makes one "click" and the color wheel spins up and then slows down and the lamp doesn't light. The lamp appears to be fine and there is no continuous "clicking" that a weak ballast would make. Should the color wheel slow down ? The tv will attempt to start three times and then the three lights will blink on the power button on the front panel.

    Already tried another lamp and no go. As previously stated a weak balast would make continuous clicking noises trying to start the lamp, this doesn't happen. The color wheel needs to make 5400 rpm for the tv to finish the start process. I don't have spare parts for this tv and to purchase the parts to test would be in the $600.00 range for the lamp, ballast, and color wheel. If I was to just replace components until it works I wouldn't need to post in this form. Trial and error is what I'm trying to avoid.

    Already tried another lamp and it didn't work as was previously stated in my post. Wheres all the experts at??

  • kirkbowlby Jul 15, 2010

    Thanks Cindy for your help, I will buy a new color wheel first and see if it fixes the problem..

  • kirkbowlby Jul 15, 2010

    Thanks for the advice on testing the ballast, I'll give it a try. Thats the help an expert gives :)

  • kirkbowlby Jul 15, 2010

    Cindy just found a video on exactly what my tv is doing and they recommend a color wheel. The noise is from a bad bearing causing the color wheel to wobble.

    Guess your advice was correct !! :)

When all three LEDs (Timer, Lamp, and Temp) are blinking, you need to replace the lamp. The color wheel and the cooling fan usually gets noisy (a buzzing sound) when either of them fails (instead of slowing down). The color wheel and the fan will slow down to avoid overheating if they are damaged past the point of them being noisy. Do you recall the TV being noisy before this problem started?

Try resetting the TV by unplugging it for 30 seconds or a minute (a hard reset). Then order a new color wheel and cooling fan. (Also order a lamp if the current lamp is over a year old (or even near a one year old).) The last time I checked, the parts were cheapest at samsungparts.com. However, you should check via google for the comparison shopping sites for more recent prices. The replacement of the color wheel is fairly easy - a few screws and a few connectors. A similar tv is repaired at these two links:

    BP31-00010B is the lamp fan (under $27) and the color wheel is BP96-01103A ($125) at samsungparts.com. The lamp is $130 but match your lamp to the available part. I've got three listed for this TV model and I suspect there may have been a manufacturing change.

  • kirkbowlby Jul 15, 2010

    I have checked the fans they are ok. The color wheel is a little noiser than it was, sounds almost like a dvd drive when it spins up. Removed the lamp and it appears fine with no smoky glass and the filament appears intact. Tried a lamp that I kept as a spare and it also wouldn't light. The power to the ballast is ok and the reading to the lamp is 7.6 dcv . If the color wheel doesn't reach 5400 rpm the ballast won't fire the lamp. Are these color wheels supposed to slow down or spin up to a constant speed ?

  • kirkbowlby Jul 15, 2010

    The tv worked fine prior to this problem. The screen was bright, these mercury vapor lamps don't usually go in a split second, they grow dim over time. The color wheel slowing down is new but, I can't find any information on whether this is a symtom of failure which brought me here. All of the information from the other two expert posters I already knew. I guess i'm looking for a definate way to determine if the ballast is faulty or the color wheel without having to buy all three parts. By the way,

    Discount Merchant has better prices than samsungparts.com.

  • Cindy Wells Jul 15, 2010

    The color wheel will spin at a constant rate except when it is failing. Then it slows down to prevent a catastrophic failure - it would break from excess heat and throw the shards into the rest of the TV. (At that point, you would need a new TV.) Definately, from your additional description, the color wheel is bad. I'd still recommend replacing the fan as well since you say that was a little noisy. (If you want to save a little now and get a few more months out of the fan, blow out the dust from inside the fan (compressed air). You can't lubricate most of these fans; they are sealed systems.)

    I hope this helps.

    (Since you tried the spare lamp, you probably don't need another.)



  • Cindy Wells Jul 15, 2010

    Since the TV doesn't stay on, I'm not sure if this will work but try to turn on the tv with a multimeter above the ballast. You need a multimeter that measures frequency (higher end multimeters like Fluke) or an oscilloscope. Hold the multimeter probes a fraction of an inch apart about an inch above the ballast. If the measurement is near zero, either the meter can't get close to the frequency range or it's bad. (Electronic ballasts like this are very similar to the ones in a fluorescent lamp.) A reading of 1 or an actual value is a good ballast. (I can't find the actual frequency for DLP ballasts; I know laptop LCD ballasts were ~20kHz in early models but now they are ~60kHz.)

    If you replace the color wheel watch the direction of the ribbon cable, it won't work if you plug it in upside down.

    I hope this works.

    (I use an oscilloscope - just have to make sure other fluorescent sources are not close enough to get measured.)

    You're welcome.

  • Cindy Wells Jul 15, 2010

    I'm glad you found something that led you to accept my diagnosis (since I didn't get to hear your TV myself). That noise is hard to describe except in a sound track.

Three lights blinking indicates that its a dead lamp. Below is a screenshot from the manual
I have a samsung HL-R5064W dlp tv that the lamp wo - 3841733.gif
You should replace your lamp to fix this as the tv is going into protect mode due to a failed lamp.

Sai.

    Be adviced that it happens even when the lamp cover is not correctly attached. The lamp's inner cover has a sensor that checks whether the lamp covers are properly closed. Hence it goes into protect mode(relays switch turning off is the click that you are hearing)It is clearly stated in the manual. I guess thats what we are all at. Yelling at or mocking the experts is not gonna help your cause.

    Sorry. Didn't get your last comment. Can you please post it again?

  • kirkbowlby Jul 15, 2010

    Checked the door switch and it is ok, bypassed the switch and still the tv will not com on. The "click" I am hearing has always been there when I turn on the tv and it has always come on before. I have read the manual and know what it says. The three lights indicates a problem that prevented the tv from completing it start up routine not just a faulty lamp. The most common things to replace, in this order is 1. Lamp, 2. ballast, 3. color wheel. But most people don't have $500.00 to through away on parts they don't need. That why I paid for expert advice not quotes from my manual. I'm no expert but I do know something about this problem..

  • eagle338

    If the color wheel is faulty then you will hear some kind of whirring noise indicating that the motor is faulty. I will look up the service manual and let you know if it can mean anything else.

Hi,
All three lights blinking shows problem with color wheel, ballast supply or lamp.
If lamp has not been replaced in last 2-3 years then replace it as lamp might reached on end of working hours life span or test the lamp in another tv that use same lamp for confirmation.
Next suspected part is ballast lamp, if lamp found OK then ballast supply needs to be checked, swapping ballast board is good way to confirm it before buying new part.
And last thing is color wheel that is suspected, I'm putting it at last because you said it spins then slows down because of protection circuits of tv that sensed some thing wrong in booting process and activates.
Take out lamp and ballast supply board and check both by installing in similar model tv to confirm defective part.
Hope these info will help you.
Thanks.

I have a Samsung HL-P5067W/HL DLP tv. When I turn it on cold the lamp light blinks on and off. The fan makes a high pitch sound a relay clicks the TV goes back to standby and the lamp light starts blinking...


This sounds like a lazy lamp--that is getting hard to start. Try a new lamp first. If you are inclined to do so--get a bard bulb and install in the old lamp housing and save some money. Get a real PHILLIPS bulb--it will last a while--compared to cheap generics that are good for maybe 6 months !!

Remove the lamp and look at the color wheel that faces it.

If wheel is shattered or missing pieces set will know it is not moving or moving too slow and shut set and lamp off.

Not all color wheels when fail make a sound

THE FAN STARTED WHINING AND NOW THE LAMP WARNING LIGHT IS ON AND IT WONT TURN ON. IS THE FAN A PART I CAN REPLACE MYSELF?


It's not likely the fan - it is more likely the color wheel making that noise and causing your set to shut down. See link for more info

Samsung DLP HLM-617W/XAA


with lamp out (door closed) the ballast should "strike" or give an arc sound, trying to fire the lamp. If it does not do that maybe the color wheel is not spinning up - has to do that first.........then the set will try to fire the lamp

Samsung DLP HL-S5087W 56" Confused...


Mine did that when the color wheel didn't spin up...just give it a whack where you installed the light & the wheel should spin up. I had to replace my color wheel as the bearing was shot & was buzzing all the time. The light won't come on if the wheel doesn't spin up first.
