I have a 56" samsung dlp tv, when I turn it on tonight it now has a shadow on the right side of the tv, about 2" wide all the way down the side. Called samsung and they told me I needed to have a repair tech come out and look. Any hints as to what may be wrong? The tv is only 1.5 years old.

Re: Two inch shadow on tv
Change the input to AV1 or AV2 with no signal and see if it's still there, if it is you might have a defective light engine in which a lot of manufacturers will warranty. This can be repaired in the home but some shops preferr to take them in, try for the in home co's first. Just a word to the wise, DLP's do not last as long as you may want.

yes you could have. Try 2 sources, cable, dvd, game system. If the issue is with any 2 then it is the tv and it will have to be adjusted by a repair center. If it's only one source then it could just be the actual source that the issue is with. You can also push the menu button and if the line is over the menu it's for sure the tv.
Hello: The problem is that a small mirror on the light tunnel has fell off causing a shadow in the picture,. In the past the only way to repair this problem was to replace the entire Optics Engine. But Samsung decided it was replacing entirely to many light engines so they decided to allow and train technicians on how to do it. It involves removing the color wheel and behind it is the light tunnel where light from the lamp shines on to a maybe 1 1/4 inch small block with three mirrors on all sides, your problem is that one of these mirrors has come loose from its side, causing a shadow with the pic still in the background. So if you call a technician to come, if he has'nt had the training from samsung on how to do the procedure then he will want to replace the entire optics engine which is the expensive way of doing it.
So when calling as if they know how to replace light tunnel. There are some adjustments that also needs to be done once it's replaced. To verify what i am saying go to this site to find out more. http://www.avsforum.com/avs-vb/showthread.php?t=758625
The color wheels will never fix an issue like that. The only things that will cause that issue is a bad DMD board which is part of the light engine or the digital board which is not. Freak Squad need to replace the digital board.
There is a piece connected to the color wheel assembly called a light tunnel. It is between the color wheel and optic assembly. There is 4 mirrors inside. One of them probably got dislodged when the wheel shattered. Sometimes they can be repaired using high temp glue or you may have to replace the tunnel.
turning off the main can be very harmful to rear projectors if you dont wait for the cooling off period, for instance when you turn off the tv from the remote, the fans inside are still on in order to dissipate the heat given out by the lamp. as a result some of the lens inside the engine may have burns-in caused by excess of heat.thus leading to shadows on the screen.
Yes, it could. There is a light pipe in the light path that could now be broken from the bumping or it could just be out of line from the bumping. Another problem could be the mirrors in the projection path could just need adjusted by the 3 screws that are beside the mirrors. This may also happen when bumped.
