    You can call California @ 1-888-942-2929 EXT. 3938 and talk to "Arun",
    he gave me the part # and cost for my color wheel installation:
    $89.00(part), $100.00(labour), $45.00(over-night shipping).Otherwise
    you could just buy the part for $89.00 and install it yourself, but
    apparently you need calibration software - and they won't sell that
    with the part (of course). I'm not sure if i'll go ahead and ship mine
    out to them ; double shipping

Samsung HLR5064W DLP TV load vibrating noise like a fan blade hitting something, lamp light is one, Tv will light up but discolored


Sounds like a bad color wheel----remove lamp---the wheel faces it--look for missing pieces or the wheel shattered---these are known for the wheel making a loud high pitched sound or even a grinding sound if the wheel shatters.

if wheel bad You Tube has video instructions for replacing it---seen several people able to do this themselves in about a hour. Google the model number to ("color wheel") to locate a replacement on the internet.10_24_2012_3_58_01_pm.jpg

if this "whirring" sound was making a vibration on the TV, there is a good chance that the one that needs to be replaced is the color wheel. When the color wheel fails it also triggers the signal for replacing the lamp. This is another common issue with Samsung DLP's.

In order to replace the wheel follow this picture guide:

This mechanical whining sound is typical of what is know as a color wheel fault. Color wheels are mechanical color disk that spins. generally if they do not reach a certain speed the set will shut down. It is a moving part and anthing that moves will eventally not move. other possiblilites might be cooling fans if they shut down then the lamp will shut down. to determine which a technician will need to remove the back and isolate where the sound is coming from.

Loud sound would be coming from defective color wheel that is mounted i light engine, next to lamp housing. Replacement of color wheel is required expertise/ experience and professional will do that for you in correct and in safe manner.

Thanks.

NO PICTURE, AFTER 5-60 MINUTES, LAMP IS LIT, AND HAVE SOUND


Hi,Do you hear clicking or like wanting to turn on? If you do it could be an issue with the board that powers the lamp, it's called the ballast.Do you hear buzzing or like a spinning sound? if you do it could be an issue with the color wheel,which is a disc with different colors that spin at high rpms to create the colors on the tv.If you don't hear any of this and tv is between 2-4 yrs most likely it's time to replace the lamp.This is your part number and here's where to find the Original Philips lamp: http://www.discount-merchant.com/SearchResults.asp?Search=BP9600677A+?Click=48173 God bless you.

Is the color wheel fine if it is spinning? Can you see any light from the dlp lamp when the screen is off? I had a service guy come by to fix my dlp and he replaced the bulb with no luck. He said it was...


First You can look on the rear of the set and see the lamp light shine through the lamp door vents when the set is on. Second you need to replace the whole color wheel before the set will work. Third Color wheels may spin but not at the correct rpm and may shut down the tv and sometimes color wheels will emit a high pitched whine or buzzing sound indicating that the bearings in the motor are wearing out. But now that you have to replace the color wheel you will need to adjust the index delay in the service menu. I suggest having a factory trained tech repair the set.

Loud whinning noise then no picture or sound


Color wheel is the noise you are hearing. It can also keep the lamp from firing up if it has seized up. Remove the lamp and inspect it. Replace the color wheel for sure.

1. Look at the new lamp. make sure it still looks good. not broken with little glass pieaces in it. 2. When you turn on the tv, put your ear to the lower back part of the tv near the middle. Listen for the start up of the color wheel (a low high pitch sound only at the start up of the motor). If this is good you will here a ticking sound only if the lamp dose not light.

Now with all this info. If the lamp lights (as seen from the back of the set) and goes out after a few seconds and you did not here the color wheel spin up, the color wheel is bad.

If you here the color wheel spin up and no ticking sound, the Ballast is bad.

The ballast part no. 939P978010

The color wheel is not avialable from Mits. You will have to replaced the light engine. It cost to much. Just buy a new tv.
