Picture is going dark to bright and making a clicking noise

I have a 56" samsung dlp that is a little over two years old. I had a tech replace the light tunnel three weeks ago for a shading problem and has worked great for three weeks until today when I turned it on it was making a terrible click noise and the picture would flicker from good to a dark contrast back and forth. After some time it would settle down but then everytime the you change the channel the picture on the channel you are on would get lighter of darker the clicking and contrast variations would start again. Any Ideas?

Hi, sounds like you`ll need that tech again, your description sounds like a bad color wheel, if you let it continue and it shatters it can & probably will destroy your light tunnell, sorry for the bad news but now you know not to keep running the set, this is a very common problem with dlp`s and it`s exactly why we tell our customers not to purchase dlp`s, gl, video-tek

My Samsung DLP 5663W was making the loud humming noise. Picture was just fine, but the noise was loud. I checked both fans which seemed to be fine, so I ordered the replacement color wheel. When I replaced...


On the metal box where the two cables from the color wheel plugged look for a tiny rectangular opening in the metal shield---there is a tiny jumper plug there, remove it carefully with a tiny pair of needle nose pliers.

One of the things they do not tell you when you replace the color wheel, it is somewhat different than the original one.

I have a Samsung 42" DLP. During the daytime I can hardly see the people and definition on the screen. It is all very dark. Nightime is better.


check your video settings there are 3 or 4 usually that all have various levels of brightness, it may be set to one of thelower ones. or you can go into tv menu and try kicking up the brightness. if no luck the lamp may be failing if not recently replaced they begin to make screen darker before they fail.

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.
