There is a humming in back of tv.the sound always good but picture doesnt come thru and i get a green screen someetimes blurry with distortion.color wheel or dmd chip or lamp starting to go out


as my experience, the most possible reason should be the color wheel or its photo sensor board.

firstly try to clean its photo sensor board, or have to replace a new wheel.

i just have this wheel, when you need to replace it, contact me freely

Optoma gt700 is all green after replacing color wheel


we mainly retail or distribute color wheel, light tunnel ect sparet parts for projector or TV, so we have experience on that problem you faced.

perhaps you ordered a compatible color wheel,but it is not big trouble. compared with your old wheel, you will find a black tape, just make it as the same position as your old wheel, it will be ok.

Samsung p6163wx - lamp sign flashing with a loud noise fan on, no picture. Replaced with a new bulb - did not solve the problem


This set may use a color wheel if it has a lamp. A bad color wheel will make a fan like or high pitched sound.

If the wheel actually shatters (it can) the set will not function and will turn the lamp off.

See photo of color wheel and if you need to know I can tell you how to look at it.

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!

I own a Samsung HL-R5067W 50'' DLP. Set is about 3 years old. Recently I heard a loud pop while viewing, picture distorted, but never went blank. I turned set off. When turned on again a loud whining noise...


Check your color wheel. There is a DIY guide for replacing the color wheel. Mine did the same thing yours is and my color wheel was all busted up. Unfortunately after replacing the color wheel my set continues to do the same thing, but this could mean I need to replace the ballast as well.

No screen or sound


there are only two moving parts in your tv a fan and color wheel, that noise is classic of a color wheel, I had the same tv and problem. I replaced it myself but it is a little tricky. part is around $175.

Color wheel


Good day, dkimberly428;
Sorry you are having a problem with your SNG TV.
Let me ask you why did you replace the color wheel? Was it making noise, but had pic prior to changing it?
Okay, if that was it, try this: the color wheel ***'y has one cable and "ribbon type" cable, correct? Okay, make sure both cables are secured. Secondly, the "ribbon type cable" was more then likely put in backwards. If I remember correctly the shiny side (end) of ribbon cable should be facing the rear of TV.
Good Luck, big IRISH. PS always double check ALL cables in TV to make sure they are properly seated.

Power issues (Tv not turning on) were typically due to faulty ballast. While the TV reports a bad lamp it is the ballast itself causing the issue. Samsung is well aware and will replace both the ballast and the lamp (since the lamp can be prematurely aged but the bad ballast). After replacment most people stop having issues.
