Question about Zenith L17W36 17'' LCD Flat-Panel HDTV (Silver)
I cannot get the picture to go full screen on my monitor since purpurchasing a new computer. It has black border around picture 1 1/4 in on the right 1/2 in top and bottom and varies from 1/4 inch on the left to picture moving off the desktop and not visible.
I cannot adjust it with computer settings or use of monitor controls. Do I need software to re-program? What do I do
Right click your mouse button on the desktop and choose properties. Then click on settings and then resize you resolution I like 1024 by 768

You should have the Picture tube checked by a professional, as thats the first thig most peeps think that goes bad when a picture is gone or bad. It could also be the crt driver circuit.

common problems with these, usually customers here a loud pop. then the screen goes blank. I would try...
Some of these have a 4 pin test on the control board that you can jump with solder to get test pattern. If you get it to do that then these boards maybe good and would replace the control board. if nothing happens, then
the upper & lower drive also the Ysus and Zsus boards all at the same time.
last could be a defective panel.
hope this helps. p/n are on all the boards.

Your TV is showing signs of age. It's displaying something called "vertical foldover" which is due to capacitors in the set's vertical output section that need to be replaced. These failed parts can stress the vertical output integrated circuit, and if that goes bad your picture will collapse to a thin horizontal line. The capacitors themselves (usually 3 or 4 need to be replaced) are pretty cheap. A TV shop in your area (if there are any still around!) could fix it and the repair should be under $100.
By moving those rings on the tube's neck (which is actually the back) you have messed up the set's convergence. Those rings are magnets which adjust the electron beams in the tube so the red, green and blue images line up correctly on the tube face. The rings are often marked with a stripe after adjustment to show how they were lined up. Look carefully at them and see if there are any marks you can go by to reset them. To properly converge the set some equipment is needed to generate the adjustment test pattern. Again, a shop could do it for you.
All things considered, at this point you might seriously consider replacing the set. Not because the troubles aren't fixable, but because other parts can start failing because of age, and by now your picture tube is on borrowed time as well.
