Re: at the top of my projector image there are a series...
You need to clean the mirrors inside your projector, you can either open the shell and use compressed air, but i will recomende u to go to someone who works with things like that. Its cheap to clean a projector by a pro, it takes a pro about 10-15 minits to do it.
If u gona use compressed air, make sure u biy air special for elecronics and nevere ever hold it near the mirrors.

it's not the lamp. if you've replaced the cords and still have the problem, reset the settings to factory default to make sure the resolution matches. if still not ok, there may be an issue with the main board.
How defined are the dots? Is each blue dot limited to the size of a pixel? I suggest you create a 3 slide image in powerpoint ..one slide completely blue, 1 red and one green. then project each image in turn and note what happens with the blue dot. My first thoughts are you have some pixels that are locked. Once that happens if are pretty much stuck with them. Optical it is impossible for a dust on the lens etc to cause them as if the picture is in focus at the screen the dust is way out of the depth of the field, sometimes you can focus the projector so that the point of focus is the lens surface but then the actual content will be way out of focus...none of which has anything to do with your blue dots.

there is a burned-in spot on the polerizer light filter for the blue lcd. it makes sure the light is blue coming through, that's why it is black on a blue screen, and yellow when the red and green are the only light showing through. it needs to be replaced. pat # PFiLW0213CEZZ.
This is one of two things. Most likely there is a piece of dust or other obstruction right on top of the blue panel. I'm guessing that your smudge is in the lower center of the screen - that is where these usually occur. The other possibility is that the blue LCD panel is starting to deteriorate and the components separating. This is extremely expensive to repair and Sharp will end up giving you an estimate that approaches the replacement cost for a comparable new projector.
Looks like your projector has done it. Thats acommon trouble to ageing polirising lens, usually the blue. less blue, the green and red make up the yellowish image on the screen. The blue is bombarded with tremendous heat from the lamp and it fade and wash out. If its free, its worth replacing. Get quote for the poliriser; 2 pieces each color. Good Luck.
might be a speck of dirt on your lens, possibly on the inside. I assume youe have wiped the outside of the lens? ;-) (I have to ask)
If the dot seems to be following pixels exactly your projector might be broken.
The smell might be from some dirt or possible an insect in the projector. Try using compressed air to blow out any dirt and dust. It might just be dirt acumulated over time that is burning to create the smell.
t t might be a long shot, but if the bulb is easily removed, yo ou might try to shine a flashlight through the lens to see if there is dirt on the lens inside.
If you adjust the image size mechanically, or use lens shift, does the speck move on the picture? If so, it's probably on the lens.
