When the TV is turned on, you can hear the motor/fans start and then a high pitched whine gets going. It was soft at first and went away for a while. It is back with a vengance and louder than ever. You cannot even hear what is on the TV.
Had the same problem. It quit within about 5 seconds after turning the TV off. Replaced the color wheel and the whine is gone. The picture also looks brighter, which may be due to dusting the projection lens with lens-cleaning compressed air (from a can). The color wheel was about $100 from Samsung parts and it took less than 3 hours to replace. See http://www.jangro.com/a/2006/07/24/samsung-dlp-replace-color-wheel/ for good info, and be sure to read the cautions.

Oct 2, 2013 - I recently had new fan belts installed after hearing a high-pitched, ... Do you hear the noise when the engine is running and the vehicle ... Just replaced water pump (and timing belt) yesterday and squeal ... When driving it make a noise but change out and caught speed the noise is coming from driver side.Missing: 1999 plymouth breeze
Ususally this is caused by a forein object has gotten hung in the suction impeller attached to the motor. the noise flucuates due to the housing flexes with the movement of the handle and rod. the housings are usually made of plastic and something very small can easily get stuck in it and stay for a very long time. The vacuum needs disassembled and the forien object removed from the fan housing... Hope this helps Sincerely Roger
THAT TV HAS WHAT IS CALLED A COLOR WHEEL WHICH SPINS AT VERY HIGH RPMS AND CAN MAKE HIGH PITCHED WHINING/GRINDING NOISES IF A FAN WAS BAD THE TV WOULD SHUTDOWN AND THE SOUND WOULD BE MORE DULL SOUNDING.
The colors wheel is dead.That why,u hearing high pitched whining sound.The colors wheel is spinning off of is motor axis and grinding it sides walls,that where the high pitched whining sound came from.Hire a tv Tech. for the colors wheel changing,because it requiring to take out alots of the machanicals parts itself,before u can come to the colors wheel itself to change it.
Depending on the pitch. humming noises are either a motor ie: fan motor or if it is very low a defective capacitor . Since you have the yellow band and the high pitched beep my fist thought is somthing defective in the power supply. Take it to an authorized servicer.
If after trying the TV again later and problem persist, repairs are in order.
A high pitched whine is an indication of a fault at the horizontal section of your TV. The horizontal provides the high voltage for the picture tube.
Your best bet maybe to seek the services of a qualified professional TV repairman since this involves component level repair, soldering/desoldering, use of soldering iron and VOM (testers) and knowledge of circuitry.
Good luck and kind regards.
The whine or squealing you hear is either the color wheel or fan. To determine which, when the noise is heard from the set, turn it off and listen carefully. If squealing stops immediately then Tthe fault is the color wheel, not the fan. And sounds like that are generally the color wheel.
A new color wheel is Samsung p/n# BP96-00250A for this model. Vance Baldwin carries them for $97.20 plus shipping. https://www.vancebaldwin.com
