It is possible that the Fan make the noise. However, if you whant to find out, just remove some screws of the lower portion of your tv (bottom right) and then you can see the fan an point out if this is your problem.

I had a noise but is was coming from the lamp.

Hi Mark,

First of all thank you for posting your question here at Fixya.

You've mentioned that you can hear a slight grinding noise. This noise came from either a faulty color wheel or fans. To isolate where the fault came from, first I would advice you to access the "error code operational check". This is a built-in software that log and give an equivalent error code by means of blinking LED to determine the exact caused of the symptoms.
How to access the "Error Code Operational Check".
1. Turn on the TV and wait until it automatically shutsdown.
2. Pressing the front panel "Input" and "Menu" buttons at the same time, and holding for 5 seconds, activates the Error Code Mode. The Timer LED flashses denoting a two digit Error Code.Example, if the error code is "42" the led will flash 4 times pause and flash 2 times and it will cycle for a total of 5 times.
Please let me know what is the error code.
If you can't access the error code mode because the TV didn't gone to shutdown. I would advice you to open the rear panel of the TV to pinpoint where the grinding noise came from.

1. Remove 8 screws (A) from the external input frame.
2. Remove 10 screws (B) form the rear cover.
3. Pull the rear cover from the TV.

Tape the lamp cover switch to closed position like on the picture above or else the unit will not turn on.

Your TV has a 3 fans :
1. DMD fan
2. Lamp fan
3. chassis fan

If the grinding noise came from the fan(s) you have to replaced it. All fans have the same part no. 299P312010
However if the noise came from the optical engine assembly, you have to replaced it part no.938P059050

You have a damaged sustain board or color engine. All 3 boards should be replaced and retuned. This is not a DIY, although many do try it they end up paying more than having it fixed right the first time. Take the tip, call in a professional and save money.
parts $400 + 2 hrs labour But swapping boards does not fix it and in fact can blow them again.

Please rate my help++++Thanks for using FIXYA

RCA HD50LPW164 turned on TV made a pop

the loud pop you heard was probably a capacitor blowing its top. The grinding noise is likely high voltage arching that was occuring due to rising voltage since capacitor isn't there to smooth it out.

When turning on the TV, I hear a banging/grinding sound.


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;

Please keep us posted.

No picture or sound

Hi, your color wheel needs to be replaced, the bearings fail causing the grinding noise, the new ones use "air bearings" so they are supposed to last much longer, video-tek

TV grinding noise

A grinding noise in that model usaully means the light engine is defective or it could be the color wheel. But light engine is most suspect as there have been some issues with the light engine assemblies

Grinding Noise

sounds like the light engine there are alot of problems with the light engines and quite a few have had a grinding noise. The only other possibility would be the color wheel. But I would lean heavier toward the light engine being the fault.

Samsung DLP HLR5668W has mostly dark picture + grinding noise

Pix looks like a light pipe issue, inside the Light Engine. as far as the shutting down, could be a bad fan causing the grinding and when stopps the DMD turns the set off.
