Question about Samsung DLP HL-P5663W 56" TV
My Samsung DLP TV has developed a shadow down the right side of the set. I've been told this is a bad light tunnel. My repair shop only replaces the complete Light Engine for about $1,000. TV is 9 months out of Warranty and Samsung would not help.
To start off, this is a very complicated procedure. I did this myself, and the actual repair of the light engine took about an hour, and the calibration afterwards took about 20. Make sure its worth the time investment to do yourself instead of having a pro do it.
To get to the light engine you basically need to rip apart the guts of your TV. If you open up the back and pull out the "insides", from here, you need to remove the color wheel, the small heat sync fan and the metal plate it is attached to. Remove everything until you get to a small metal tube that kind of looks like a sight on a rifle if that makes any sense....There are two very small screws on the top and right side.
BE WARNED!!! these are horizontal and vertical adjustment screws, so count the number of turns you make to get the settings back to where they were after this step.
Loosen the two screws enough to remove an even smaller metal tube inside. There are 4 mirrors inside (BE CAREFUL when handling them) and odds are one or more of them came loose. I used some glue on a Q-tip stick, or a toothpick works too, and secure the loose mirrors in place.
Once the mirrors are secured, put everything back together again, and fire up the set.
The best way to make further adjustments, if they are needed, is to have someone look at the screen while you adjust the horizontal/vertical screws I talked about earlier. A second option is to go into the TV's factory setting menu and use that, but that is really for minor adjustments, so use carefully.
Hope this helps, and let me know if you have any questions.

It is not the light engine, it is the light tunnel. The tunnel is four small pieced of crappy glass in a aluminum tube the size of tootsie roll. I took mine apart today and one of the mirrors simply moved out of place. Need more help email me at firstname.lastname@example.org

You can purchase a light engine from D-M.com for a reasonable price. I've been buying them for our service center and they are working out great. The problem is that you need to make sure they have them in stock..

You can replace just the light for much less money. Check out the posts here. http://www.avsforum.com/avs-vb/showthread.php?t=758625&pp=30
