This is because one of the mirrors in the light tunnel have fallen. Common problem on your model. There are several ways to fix this, I have seen some people be able to go in and glue it back in place, others have bought a new light tunnel and put it in, and some have to replace the whole light engine to get it back to normal. The difficulty with this repair is the mirror that we are talking about here are small and difficult to handel and get back in the right place. The light tunnel is located next to the color wheel. There is the lamp to the right of the color wheel and the light tunnel is to the right. If you decide to try to fix the tunnel yourself be careful it is delicate and not always easy to do. Let me know what you would like to do and I will help out however I can.

    I just replaced the lamp and when I started the tv it came on fine, but it has that dark strip about 6" wide running down the left side of the screen and you can see through it. Where is this mirror located in conjunction with the lamp?

There are 6" wide gray bars on each side ot the TV


The grey bars signal that the source image is originally in 4:3 format - if you are using a box of some kind get in its menu and change the format from there to 16:9. The black bars appear when a 16:9 image is sent to a 4:3 format in Letterbox mode - leave it like that or the Pan and Scan mode will chop the sides.

Toshiba LCD 37" with gray band and blue line


Unfortunately you are right it is the display panel going bad. You can either live with it or buy you a new tv as the panels usually cost as much or more than the tv. Sorry.

Gray line on left side of screen


I spoke with Samsung - they said this is a minor and easy to fix problem caused by a "blocked or collapsed channel" - whatever that is. They also recommended that if I have any warantee coverage (I do) that I not attempt this repair myself and that a technician be called in. That's my plan. I hope this helps.
