Samsung hl-s5087w noise problem

Here's an interesting one for you guys..
My tv is making a very ugly noise, it is so loud that i can't watch anything now and plus the screen flickers at the rhythm of the sound.

After reading some posts i came to the conclusion that it was the color wheel, which I ordered and replaced after watching some pictures of how to do it. Guess what, the problem is still there.
I though there were only 2 moving parts on a dlp, the fans and the color wheel. I disconnected the fans to isolate the problem and i still hear it. 
Then I disconnected the color wheel to isolate it also and it is still there!. I hear the sound somewhere behind the light tunnel and the projector lens.
Does somebody have any idea?

    thanks, but what is the light engine? the projector glass? the dlp chip? the entire thing?

    Slinteriors, your answer is the best i've heard yet. I may have found what you reference as the shutter. I will post here what i posted on avsforums, one user was telling me it was the fan or the wheel for sure.


    As i say on the post, i found a site where they sell complete LE's for 370 and repair for 300. They might be refurbished but i dont care. For the moment, I like my solution better :)



    -------


    Thanks for caring about my problem and replying to me. I really appreciate it. However, i must tell you, you are wrong 

    How can it be the fans or the color wheel when im saying i disconnected both of them , even the lamp to isolate the problem and i was still able to hear it. Today all day at work i kept thinking about what could be causing this, I couldn't wait to get back home to identify the problem and I even resignated and started to look for new light engines. Most of them cost like 900 bucks but I found a website where they sell the whole LE for 379 i believe. Having the idea on my head that I'm still going to need to buy a new one and that it is not that expensive to replace it, I got home and started to work on it. 

    I disconnected the video cable, the left side connector and the one on the back of the LE (these are the only ones needed to take the thing out) and started unscrewing the lens cover, took that whole lens part apart. Connected everything again without that and the noise was gone.

    So I started to drill down on that single part, first thing i did is unscrew with my hand the lens that points to the end of the light tunnel, i saw no moving parts there so i moved to the next part (careful when doing this, remember the exact location of where you unscrewed), the top lens doesn't unscrew and i almost break it, it looks like it's glued so that one doesn't move. Next I removed what I think it is the DLP chip but i'm not sure (glass actuator bp64-00548a), it is just a small mirror with nothing that looks like it would be making that big noise. The only thing left was this sort of relay looking thing on the bottom. I unscrewed it and bingo! It had this weird looking metal hook that i started moving with my hand and I could see that it was the source of my problem. I honestly can't think of any reason why this is needed. I guess when it moves too fast since it is in the direct path of the light it could create this strobe effect. I dont know..

    So to make sure, i connected that cable to the LE, with that thing open, as soon as i fired the tv on, that thing started to move from left to right like crazy, really it moves so fast that you don't even see it moving. I don't know what its purpose is but after wondering how to fix it and looking for the part on the net without success (part no. oc-dbh1h21b-006, db0617-a2187), this was my solution..

    I disconnected it!
    (picture attached, it is the thingie on the left side)



    OMG, since I had already replaced the color wheel yesterday and the old one wasn't spining as fast as this new one, my TV is a lotttttttt quieter than when i first bought it. I don't know if it will working next week because of it but right now i'm happy with it  my colors didn't even change after changing the color wheel so everyone that's thinking about how to do it, i've been researching this stuff for 2 days now and i already dissasembled the whole thing, don't fear, specially if you're out of warranty.

    oh, another thing, if someone decides to unscrew by hand the lens that points to the light tunnel, mark the distance horizontally and mark a line betwen the two screws.. or remember the # of turns to take it out, which will be a lot. I dont know how i remembered the distance but when i first put it in there image was all blurred, i had to remove everything, recalcuate and hope for the best. I honestly dont see the point of removing this part of the lens though.

    next project: changing my light tunnel.. i've been having the widely known shadow on my right side for a while now. I called samsung today and they will replace it (bought tv on 10/06) but they want me to pay for a diagnosis first, it will be cheaper if i buy the part and replace it myself.

    thanks for reading!

    the light engine is what processes the lamps beam and aims its at the DLP chip Mirrors. It has a shutter and chances are the sound is coming from the shutter. If thats the case the light engine will need replacement. But if the color wheel and Fans have been ruled out the only other component that can make noise is the light engine they cost about 1000.00 to replace

My Samsung TV makes a loud humming sound when I m watching it. It is very annoying. What could the problem be?


Color wheel would be first suspect followed by a fan needing replacement. But if its a real loud humming I would almost bet its the colorwheel.

Keeps a lot of noise


please clarify. Does your TV make a loud humming noise when its on and when you turn it off do you hear it go away. If so its your color wheel.

Why is my Samsung DLP Television is making a static noice when turned on?


Hi, what do you mean by static noise. Is your station unclear. Does this only happen on the cable coax connection or is it a loud noise. If its a loud noise then its your colorwheel if its an unclear station or channel then more then likely its your main input board. Please let me know if that helps any.
