Shadow on the image

There is something getting in the way, between the lamp and the lens, I guess, that is visible, as a shadow. This shadow is not covering the complete image. I thought it was that circle in front of the lamp (filter I guess), so I rotate it manually, the shadow shift to another position; I can't manage to make it disappear, because but it is shifting every time I move the projector. What can I do? Is there any repairing guide? Many thanks

SOURCE: BenQ MP610 Video Projector Shadow

This model is now out of production. It was sold as one of the bottom end of the "DLP" projectors. It's basically a "good cheap" model using a 1.5cm DLP mirror. And being as such, over the year the "thermal cycling" has most likely caused the alignment to shift. It could have collect some dirt in a quadrant of the lens too. That's possible too. Being a manual focus, there is at least no "auto focus mechanism" to worry about. That can be a pain to adjust. You could fix this yourself with some luck. It either has three screws to adjust or it has an ellipictal ring arraignment and you'll need a two correct size spanner wrenches. If it was in front of me I could tell you right away. In any event, if you turn either one of the screws the wrong way it can get worst or if you don't have the correct spanner wrench to adjust it either you can be more trouble. Plus you need to do this with a light source "on" so you can see the effect. Your best choice in this case is to go to a camera repair shop. One that doesn't send their repairs out if you can. (you have more control over the repair) It's an "adjustment and cleaning" and shouldn't be that expensive to do. Please let me know the results when you decide.

SOURCE: Benq Projector MP721 stops illuminating after

it might be dusty enough to hold in the heat. it needs a good cleaning. use canned air. if you still have an issue, the fans might be running too slow or the thermister (temp sensor) may be faulty. sometimes if it gets too hot in there, the thermister needs to be replaced, too.

A shadow on the picture


The shadow could be caused by a dust partical that is trapped. You could try to dislodge it with an air duster or a vacuum with a soft brissel attachment

Tip

Shadow in the image


If you see a shadow in the lower part of your image when shooting with the built-in flash, it's probably the shadow of your lens hood.

Try removing the lens hood. If that doesn't work, perhaps the lens is too long/big: consult your manual: the manual should tell you which lenses cause shadows. Otherwise, try using a shoe-mount flash or off-camera flash.

Shadow on image


Usually, this is just caused by dust inside the optical block. It can usually be remedied my removing the lamp, and just blowing out the unit with an air compressor. Canned air won't do the job.

TOSHIBA 57LX177 SHADOW SPOT CENTER OF SCREEN


If my research is correct you recently replaced the lamp and then the "shadow spot center of screen" appeared.

Three possible reasons I can think of for this:

Something wrong with new lamp or on face of lamp--never touch the face of a lamp as oil from you hand can leave a residue and damage the lamp or cause a image issue.

Something inside on the optical lens or even the mirror causing this--not likely but possible.

A defect in the optical light engine in the set---usually if heat which comes from the lamp damages the engine it will be a color and not black---engine has a series of lens and baffles inside that heat can damage--causes minute separation inside of the lens etc.

If the old lamp works at all try putting it back to see if same issue--did you replace just the "bulb" in the housing or the whole cartridge?

If remove new lamp look at it and where it faces--usually a clear lens faces it and if some dirt on that..........

I'm using the Nikon ECLIPSE e800 microscope and for some reason there is a shadow on half of my slide. Also, I can usually find and take pictures of slides with the lamp adjusted at about 5 or so but...


There are a few things that could cause a shadow in the field of view. First if the condenser is not centered, this can create a crescent shaped shadow and rob your image of light. Center the condenser and raise it to within about a 16th of an inch from the top of the stage.
Second, the slider on the head which diverts light from the eyepieces to the camera must be fully engaged to the "camera" position
Third, make sure that the diaphragm on the condenser is not closed too far. There is an adjustment ring for this. Set it to 70-80% of the numerical aperture of the objective you are using.
Fourth: if there is a "swing out" condenser lens you will need it completely in or out depending on the objective you are using. for 2x-5x you need the swing out condenser lens completely out of the light path. For objectives 10x and up you need the swing out condenser lens completely in and centered in the light path.
If these things are properly adjusted you should not have a shadow in the field of view. If you still have a problem, let me know.

Grey shadow appears in the centre of every picture.

Shadowing on a Boxlight 6000E


look at the diffuser lenses just after the lamp. there should be 2. the second one tends to have burn spots after a while in dusty and hot conditions. if the lens is ok, look at the lcds with the light on. do you see shadows on the panels? if so, you have a main board issue. if not, you have a misaligned mirror.

The camera has a main mirror that you see with the lens off and a sub-mirror underneath the main one. It may be the sub-mirror is not flipping up completely when you take a picture. It could be off its hinges or damaged. Any good camera repairman in your area should be able to confirm this
