    i don't think it's your lamp, i have the same problem, the sound is like a loud fan and the picture looks a little like sepia, i think it's the colour wheel, anyone else got an idea for this?

What would effect the picture quality the color wheel or lamp?


The color wheel is your suspect.......usually whines a bit
when bad. In a quiet room, you can hear it when the TV is powered on or off. It spins at 9,000 rpm ( wears out the bearing).
The lamp will not exhibit those symptoms....

TV made a big popping sound, and then a crackling


Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php That crackling sound could be of the color wheel: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 noises. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is BP9601073A you can find original here:http://www.discount-merchant.com/Samsung-BP96-01073A-lamp-p/samsung-bp96-01073a-lamp-oem.htm?Click=48173 .Have a blessed one!

RCA HD61LPW42 - no picture


I haven't worked on an RCA DLP but have on Samsung DLP, based on your description it sounds like the color wheel is bad. Take the back off and turn on TV make sure its not a fan making the noise ,but most likely its the "wheel" it is inside the light engine probably right next to where the lamp is plugged in. If the whine comes from this area definitely the wheel.

Projection tv has really loud buzz or hum


You may not see any deterioration in the picture when the color wheel begins to go bad. The noise will get louder and eventually, it will shut down or the wheel will shatter while the motor continues to spin. If that happens, you'll have a black and white picture.

If its a Samsung DLP that is mercury vapor lamp driven, its a safe bet the color wheel is going bad.

Mitsubishi wd-65831 one night worked fine next day nothin..


If you hear a whining noise, the odds are it is the color wheel, the bearings are bad in it and will need to be replaced as a whole unit, kinda pricey, my suggestion, sale the bulb and all boards in it and which should fetch about 400+ and invest in a new TV, a color wheel is pricey unless you can find a deal

No picture when I turn the TV on, I do get sound


You either have a bad lamp or color wheel. You should always try the lamp first and 9 times out of 10 that is the problem. If you heard any grinding or whining sound or your unit vibrates it would be the color wheel.

Samsung dlp


HLS4266W 43" dlp. In less than 1 yr whining grew worse, but did know what it was. Year passed with warranty and lamp went out. Replaced lamp. Worked for 3.5 hrs. Turned on next day and did not work. Got another lamp, but did not work. Figured out might be color wheel. Replaced it too. TV started up. Watched that night. Turned on next day, heard loud pop. Lamp never came on. Withdrew and reinstalled lamp a couple times to see if that worked. Did not. Currently, with new lamp and color wheel installed, lamp light blinks, but no lamp comes on. What now?
