My tv has developed a 2 inch wide vertical shadow on the left side of the screen. could this be a cause of a child throwing a ball against the side of the tv? the image is still visible but has a shadow over it.

Re: samsung dlp tv
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.

Uh Oh! Your light engine is warping a little from overheating and
is distorting the picture. It usually means replacing the light
My suggestion to you is to get on the phone with Samsung and start
complaining, then keep complaining until they agree to pay for it. You
may have to get the problem diagnosed by a pro before they agree to pay
for it though.
Hope ya fix it!
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
look i need to know a little bit more of your problem so i can help you!
let's see first of all how often is the problem happening ? after a wile the lines go away or they are always there? please let me know because i think i now what is the problem i just want to make sure!
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.
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.
