Re: replace light tunnel

A simple adjustment that in my case took only 15 minutes and not only eliminated the 3" wide shadow I had, but improved the picture quality as well. The technician compared it to dialing in the scope on a rifle. Simply loosened off the mounting screws of the "mirror-Light tunnel assembly", moved it downward slightly and retightened. Connected it back up and better then new. He did say it can require a couple of attempts in some cases but mine was the 2nd he had successfully done today. Anyone who is out of warranty, by all means try it. The assembly I am referring to consists of items 16 thru 21 of the L680 Engine assembly from my 6178.

I replaced my lamp and my lamp ballast in my dlp tv but i have a dark picture its samsung hl56a650

As long as you used the correct lamp and ballast, about the only thing left would be the light tunnel which is part of the light engine(optical block) which is very expensive to replace. Was it like this before the old lamp went out? the only time I've seen this at the shop, is when the wrong lamp was installed, but have read about a light tunnel failure as a possibility. This is kind of a long shot, but look at all of the electrolytic capacitors on the power supply module if you can get to it, and see if any of them are bulged or domed on top rather than flat. I have seen caps cause this with different brands, but never on a Samsung. It may be worth spending a few dollars to let a shop give you an estimate on it.

Samsung, DLP TV 50 inches Model # HL-T5075X/XAA

Samsung just told me they wouldn't fix my tv because it was produced in Nov. of '06 and the only ones they would fix were made in August of '06 or earlier. I am way too angry right now to call the service tech number they so very nicely provided.

Dark edge of screen

there is a part inside the engine(the part that produces the picture) that is a mirror tunnel. The actual part name is "light tunnel" this tunnel takes the light from the bulb and compresses it into a smaller beam of light that is then shined onto the DMD(million mirrors) this produces the picture on a DLP TV. this mirror tunnel is glued together on all edges. One edge of your "light tunnel" has started to come unglued and has slipped a little. This causes the slightly dark area usually on the left side of the picture that you see. the light tunnel can be replaced as a single part. much cheaper than replacing the whole engine.
