Replace Color Wheel

I have a high pitched whine from the rear of a Samsung HLN 5065W TV. I think it is the color wheel bearing failing. Is this so and if so how do I repair it.

    I have sound but no picture and also have a high pitched whining noise coming from the rear.  The noise cycles for about ten seconds then stops,  then does it again.  All three lights on the front panel blink and the TV will shut itself off.   


    According to owners manual,  three light blinking means the bulb is bad,  so I replaced bulb today,  was not the bulb.  still have same problem.

If the problem is the colour wheel there is a slight delay when first turned on.If the colour wheel is at fault it is located right adjacent to the lamp it is pretty easy to change with 2 screws holding it in place.they are about 100 to 150

MY SAMSUNG HLN 507 WX/XAA T.V. IS MAKING A WHINING SOUND WHEN I TURN IT ON


Your color wheel is going bad, when it fails the TV colors will be way off and it will shut down. They range from $50 -$125 . Here is one for $98 for your tv. http://www.amazon.com/Projector-Replacement-Samsung-HLN507WX-HLN567/dp/B00HJOLQ7G

It is much more likely considering all these the wheel fails to be your issue.

The problem is often described as a fan like or high pitched sound which since the motor on the wheel turns at over 12,000 rpm is likely to be the cause.

Hint: most color wheels if you listen from the rear when the set is shut down the whine/fan noise instantly slows down until the wheel stops.

Eventually wheel will seize up and shatter and set will not come on.

I have a humming noise coming from my 5 year old samsung 50 inch dlp tv , I have replaced the lamp 6 months ago so what else couyld the noise be coming from? I have a great picture and color.


If it is a high pitched whine it is most likely the color wheel; the bearings in the wheel go bad and if you google the model number with color wheel you will find it.

The whine is the early stages of the wheel failing; when it goes out you will either have shutdown or a grinding sound.

Let me know if you have questions as I am here to help.

Samsung HLP6163WX/XAA DLP HDTV - lamp and noise issues


Hello:
Replace the color wheel again, its gone bad again. the clicking is the ballast trying to fire the lamp. The Ballast will not fire the lamp until the color wheel has reported it has reached an RPM of around 9000rpm. This is a normal sound. Most of the time the color wheel will make a loud whining sound when bearings go bad, sounds like a Airplane using reverse thrusters when landing and a even louder sound when it shatters in the housing. Also the reason it may of gone bad so soon is because they make to versions of this color wheel, Bearing type and the Air type. I don't know who installed your color wheel, but it should of came with a small tag or paper of some sort with numbers on it. Most people throw this away when it is very important to let the unit know which type of wheel is being installed to set the parameters for either type of wheel. Most people who install colors wheels themselves to save money do not know this, and the only way to install the new settings is thru the Factory Service Mode. There are also color parameters to input for the type of wheel being used.

This is your basic Color wheel 101..
Hope I gave you some insite of what may of caused your problem...Please leave comment if more info is needed..Lavell

Samsung DLP HL-R4266W..no sound or picture. TV is completely dead


Assuming the noise is a high-pitched whine, then yes, it is the color wheel.  If the color wheel goes out, the TV will turn on for a while, then turn off when it can't establish color wheel sync.  The color wheel has to be in sync with the mirrors on the DLP, so if sync can't be established, the TV turns off.
You can order a new color wheel from Sears or partstore.com (among other places) and replace it yourself, if you are so inclined.

HL-R6768W not turning on. High pitch spin sound. Bad color wheel?


The high-pitched whine is definitely the color wheel.  The early color wheels had problems and many had to be replaced.  As part of the turn-on process, the TV checks for light and then checks for color wheel sync.  If the bearings are wearing out/dried out, it could cause issues with getting the proper color wheel sync, causing the set to not pass the turn on sequence.
Check Sears or partstore.com for a color wheel.  I like sears for experimental replacements since they allow easy returns.
BTW, mine is an early 61".  My color wheel was replaced when I had to replace my Light Engine.  My in-laws 50" was an early one and theirs went out within 2 years.

High pitched whine when the motor starts


Had the same problem. It quit within about 5 seconds after turning the TV off. Replaced the color wheel and the whine is gone. The picture also looks brighter, which may be due to dusting the projection lens with lens-cleaning compressed air (from a can). The color wheel was about $100 from Samsung parts and it took less than 3 hours to replace. See http://www.jangro.com/a/2006/07/24/samsung-dlp-replace-color-wheel/ for good info, and be sure to read the cautions.
