I have a HLS5087W that is 3.5 yrs old. My problem first started with the TV shutting off by itself. I would turn it back on and watch for a while, then it would shut off again. Often this occured for approx 20 minutes, then it would just stay on without shutting down. Now when I first turn on the TV, I hear a banging/grinding sound, but after 10 seconds, the TV is fine (good picture, no banging/grinding). Most days, the TV will run fine for hours, but then it shuts itself off. When turning it back on, the banging/grinding noise starts but doesn't stop. It even continues about 30 seconds after the power is off. The TV then will have to be off for several hours, before it can be turned on without the banging/grinding continuing. I have replaced the bulb, but feel maybe the ballast or fan may be the problem. What sould I try next?
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.
