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.

I have Samsung DLP TV 50 inch HL-P5063W


First thing to look at is the color wheel this model uses--usually it will make a high pitched fan like sound but can make a grinding sound also.

If it slows down from the 12,000 or so RPM speed it will cause color issues.

HAVE GRINDING OR HIGH PITCHED SOUND?

Loud grinding noise when the lightbulb is on


Hi,If your tv is a dlp you might be experimenting a color wheel problem.The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming ,grinding,buzzing noises.

No picture, siren type noise as restarting


My Toshiba dlp 62hm116 was used for 3 months then stored for 2 years, I turned it on yesterday and it makes a loud grinding noise which I think is probably from the exhaust fan area and the picture is black except white at both vertical sides. It worked fine the last time I used it 2 years ago. Any ideas?

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


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

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 went pop


All you can do is get it repaired or replace. Take the receipt (if you still have it) to the retailer you bought it from and ask about it. Alternative, phone Samsung (number is probably in the instruction manual that came with the TV, or look on their website) and ask if they can do anything about it.

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

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.
