It's probably something on the sensor. Try removing it with compressed air.

When i look through the view finder i see a black dot. What is that from?


This camera has an electronic viewfinder. It allows the image captured by the lens projected electronically onto a miniature display. It also allows you to see real time what ever adjustment you make on the camera(same w/ the lcd screen). That black dot that you're seeing could be dirt or a dead pixel. If it's a dead pixel it can't be removed.

Sir, its white small dots on complete screen, like sky with stars,


Place a white piece of paper about 1000mm in front of the screen and focus the image sharply.
Choose menu, image, advanced then select color manager.
go through the color options and check if some pixels are permanently on or off (ie small dots or black) instead of a uniform colour on the screen.

The DLP chip is most likely the faulty component

Canon power shot sd1000 black dot on lens


If by saying the upper right corner of the lens you really mean that there is a dark spot on each image AND the rear display, there may be dirt or dust on the lens itself. Clean the lens with an optical quality cleaner. Do not use paper towels and Windex or the like - as paper towels can scratch the lens.

It is also possible that the dark spot is a "stuck pixel" on the image sensor inside the camera. There is no way to repair a stuck pixel outside of replacing the sensor. Any dark spot (regardless of source) can be edited out by using image editing software. This will allow you to to make the dark spot less noticeable - or practically invisible.

If the dark spot is on the rear display only, it can also be a result of a "stuck pixel" on the display itself. This should not show up an images, but only on the display. There is little that can be done outside of replacing the entire rear screen.

There are other things that can cause these problems, but those listed above are the most common.

I hope this was Very Helpful and good luck!

Epson 9800 Prints black dotted vertical line


This is a workaround - I too need a definitive answer. Symptom: black dotted vertical line 1/2 to 3/4" from leftmost image edge. I have begun adding single vertical line to my prints .25" from the left edge of the paper to force the "dots" off my print - this seems to have the desired affect, but it does not answer the cause or provide a true remedy (it will save many of your prints while we wait for complete solution). dkh

Black dot.


Ensure focusing is spot on. if your image is a black dot surrounded by white light (like a doughnut) then your not in focus. Look at making a Hartmann Mask (really easy, just google for it), which fits over the front lens. It has 2 or more holes in it,this means when you look through the eye piece you will see double images, adjust focus until the images merge into one (if the images go further apart turn the focuser the other way), when they are merged remove the mask and presto you should be in optimum focus. Always remember telescopes are very sensitive and focussing requires delicate adjustments.

Viewing planets and stars


The problem is you are way out of focus. Turn the focus knob alot, until the star image gets much much smaller. Keep going until it looks like a pin point or a star!. The spider vane and center black dot will disappear. This black dot is actually the secondary diagonal mirror reflection in the primary mirror. The peace signs are the secondary supports. Use the lowest power eye pieces. I would not use the Barlow lens that comes with this scope as it very poor quality. Also, using this high power with this small an aperature (tube diamter) & unstable mount will be very difficult indeed. Invest in some wide angle, long eye relief low power lens. Use these for a while before going to higher powers.

2 ISSUES: 1) Pencil tip size dot in the middle of the projection. 2) weird smell coming from projector vent.


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.
