Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,vertical lines,color distortion or white dots on screens. Here's a video for a samsung (It's the same technology as your Toshiba) that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q IO didn't find the DMD chip by itself but with complete light engine here http://www.discount-merchant.com/TOSHIBA-050915660-p/1172913.htm Have a blessed one!

There is a vertical black bar along the left side of my TV. It started as a thin yellow/white bar and has grown to be about 2 or 3 inches wide, blocking that portion of the screen.


The LCD wafer has gone bad, and more lines will begin to appear over time. It can be replaced but the cost may be comparable to replacing the entire television.

Check and replace all the electrolytic capacitors at its vertical output section circuit. There will be five or 6 of them. Replace all.

Thin white veritcal lines


I am inclined to believe that this is a DMD board related problem. It is possible that you have got a faulty replacement DMD. It is what causes the light to be reflected on to the color wheel and if some of the nano mirrors are not functional then you will see white stripes in the place of the actual pixel. Contact the store where you got it from and return it for a new board.

Let me know if you have any further queries,
Sai.

White vertical lines in image w/ 2 inch black bar horizontal.


the black bar is from the light tunnel collapsing. the white lines are from the colorwheel or the main board has a cold solder joint. replace the tunnel and colorwheel and have the main board looked at.

Vertical, pencil-thin blue line appears after 10 minutes of viewing (any source)


I would suspect a connection breaking down as the set heats up. A shop will probably have to put the set in a stand to hold it while they check for loose connections or defective components inside. Not a DIY job by any means. If this line went completely through the picture either vertically or horizontally and stayed there then this would have indicated a failure in the Panel itself. A thin Line any where on the screen consisting of one pixel in width is a Panel Failure according to Hitachi.
