Shadows on the left or right (if the projector is ceiling mounted) of the projected image area has nothing to do with the DMD it is the light tunnel tha is at fault. See other posts about this problem.

Is your projector ceiling mounted? This is a common problem with these projectors, I am assuming that this projector is ceiling mounted because the shadow would be on the left if it is the right way up. This is caused by the light tunnel (a sort of hollow box made of mirrors) collapsing. It will have to be replaced but can also be glued (araldite epoxy or similar NOT SUPER GLUE) back together if the mirrors are still in good condition but requires a lot of patience. Best left to someone who has done this before as the colour wheel has to be removed and this is very delicate.

If a house is 1400 square ft. How many linear ft does that convert to?

if the area is 1400 square feet the lineal is 149.6 ft outside edge from a square 37.4 feet on a side, to 2802 ft outside edge from a rectangle 1400 by 1 foot wide. After that the calculation is the number calculated by the formula below multiplied by two plus the length of the ends. The narrower the strip, of course, the longer the linear distance until you have an infinite length line of infinitesimal width and you have created a perfect mathematical construct of two dimensions
The calculation for determining the lineal distance that the internal area can be converted to is:
L=1400/n where n=the width of the strip required in feet
eg in 1foot wide strips n=1 so L=1400, in 6" wide strips N= 0.5 so L=2800.

My zenith lcd tv has horizontal black lines whih form a band about 3 inches wide across the screen, sometimes the band looks more like a dark shadow than lines other times the right side of the screen...

This is either 1 of 2 things, first it could be faulty panel tabs , in this case, there is nothing you can do and is unrepairable....2) you could take the back off the tv and you will see 2 ribbons going from your t-con board to the panel tabs (top center of tv) remove them carefully and reseat them. This is a common problem. Tv repair tech 15 years! Best of luck.

Symphonic 32'' lcd tv has shadow on right side of screen

The "shadow" indicates a failure either of the LCD controller, LCD connector, or in the worst case, the LCD itself. A loose connection between the LCD and the LCD controller can result in abnormal displays. Try tapping the back of the TV and check if the shadow can be affected. If it is affected, try cleaning the connector terminals with a soft-bristle brush and alcohol or lacquer thinner. If not, have it checked by a qualified technician to carry out the proper tests to determine which of the LCD controller or LCD the problem lies.

Do you have the projector inside a hush box? If so, it could be too far back in the box. Readjust and see if that removes your shadow.
You may have a haze on your lenses. Have you tried cleaning your color wheel and associated lenses? This procedure is for the skilled since you must disassemble your projector. Keep in mind that the color wheel is VERY, VERY fragile. Use a lens cleaning agent or 91% isopropyl alcohol and q-tips. The agent must not leave a haze. Have plenty of time and patience since this may take you about an hour just to clean the color wheel. Did I mention that the color wheel is VERY fragile…

Shadow down right side of screen on a toshiba 44NHM84 44" DLP television

shadows at the bottom of the screen sound like moisture that was "wicked up" between the screen layers and dryed out leaving a stain. DO NOT get these screens wet, use nothing but a damp soft cloth; just a few drops of water running down the screen can cause a fairly large stain. Some people have suggested that they may be professionally cleaned, but the risk of damage is too great on the user level.
