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.

If using a cable or sat box try a DVD etc when set cold, a box can cause lockup issues via signal.

Not a color wheel is correct, more likely a DMD which is rather pricy and almost as much as the entire light engine which comes with it.

About $600.00 to replace. That's why manufacturers stopped making DLP sets because longevity is horrible. 5 yrs MAX if your lucky.

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.
