Hear a whirling sound within a few seconds of tv image coming up - continues while watching and winds down when the set is turned off (fan?)

A fan like noise is 98% of the time the color wheel.

Wheel turns at over 12,000 rpm and common failure is "fan like sound or even grinding sound".

When these sets first came out if the high pitched sound started women who have better hearing in that range usually hear it first.

If wheel really fails it will shatter and set will not come on----a grinding sound may be noticed just before total failure.

do you hear any winding, whirling or screeching noise. What you may be hearing could be the color wheel.

Hi,

Well basecally Samsung most comont parts that go out are,
LAMP: The generic lamp will go from 3500 to 4500 hours and a phillips lamp will go for 6000 to 8000 lamp hours,
How It Works The lamp itself typically uses AC current and about 15,000 volts to ignite the lamp's mercury vapor gas. The gases inside the lamp react when electricity charges up the mercury gas creating very bright light. The voltage drops to keep the flow of electricity to the lamp. The lamp works with the ballast to project light into a light engine that separates the colors of the light, then recombines them with an image. The image is then reflected on the back of the TV and then onto the screen. But you need to listen carefully for any strange noise like (CLIKING,HUMMING,BUZZING,WHIRLING SOUNDS) that will help younarrow down whats is wrong with yor tv bacuse the BALLAST wich is the board incharge of sending the correct amount of current to your lamp could be weeek and will not power up you will hear a cliking or electrical huming Also the color wheel is a commont part that goes out on Samsung and that will give you a vibration and a loud whirling sound,you can get more help and real good prices at http://www.discount-merchant.com/?click=52978 good luck and keep us posted

These models usually suffer from a bad color wheel. You will know that the color wheel is at fault if the sounds goes away right when the lamp shuts off. Look at the back of the set and watch for the lamp to shut down. The color wheel is not a consumer replaceable item.

Hi,

If you hear a grinding,whirling,spining or buzzing sound, that sounds to me like the COLOR WHEEL,the reason for that is because your color wheel spins at 5,000 rpms(revolution per minute) and something that modifies the balance of the disc can cause different things,Unfortionatelly the only way to check that the color wheel is working properlyis you need to check it out physically

I did some research and I found the color wheel at DM;http://www.discount-merchant.com/Samsung-Replacement-Color-Wheel-HLS-HLT-Series-p/samsungcolor_wheel_bp96-01579a.htm?CLICK=52978

the fan will continue to run after the power is shut down on a DLP television untill the set has cooled down . But it should shut off within a few minutes

That's probably the Color Wheel you are hearing. When you turn the set on the color wheel has to run, one of the several things that has to happen for the set to come on. The color wheel sends a signal back to the control circuit to tell it it's running. If these sets fail to light the lamp they will shut off and try again, that's why you hear the color wheel start then wind down then start again. The set should try three times before it decides it's not going to be able to turn on.

One way you can tell the difference in the fan sound and color wheel sound is if you can get the set on, let it run for a little while so it gets warm, then when you turn it off the color wheel will start winding down but the fans will continue to run for a minute or two.

The color wheel is the most common problem in DLPs that cause noise. To determine the cause: Turn the set off. If the noise goes away after about five seconds, then, the problem is the color wheel. If the noise goes away one to two minutes after shut off, then, the problem is a fan.

After 11 years???? OMG This set is a tired pup and should be put to reast. My experience with older sets and your complains are all capacitor problems and is only gonna get worse as the first time around repair will take several capacitors to repair. This set has no user serviceable parts inside so you should not attempt a repair suchj as this on your own.. This repair if you decide to go through the first time will be About 300 to 600 bucks the first time and cost will continue to raise till the sets put to sleep. Good luck
