Question about InFocus IN72 Multimedia Projector

1 Answer

IN72 psychedelic traces

Watching a scene with people moving across a dark background, there are traces following movement.

Rather than streaks, it is a series of ghost images or echoes of the movement that linger on the screen.

Anyone see this before?

    But did replacing the bulb solve the problem for rickrickie?

  • mherbster Mar 03, 2009

    I have the same problem and was wondering if replacing the bulb solved the problem? If it is the bulb would I have other distortions or would I have other issues that would pin point the bulb as the problem?

hi, usually you can correct this issue with only a few system checks, dark streaks can be caused by damaged pixels on the screen, in which case you need to replace the TV.
  • Inspect where the dark streaks are on the television. If the streaks occur at the same place on the top and bottom of the screen, they are due to the formatting of a movie or television show you are watching. This is normal. Also, if the streaks appear on the left and right of the screen, they are due to the show being filmed in full-screen instead of wide-screen. This also is normal.

  • Change the input setting so you are viewing the contents of a different device. If the dark streaks are gone, you know they are due to the device connected to it. However, if the dark streaks remains no matter what input the TV is connected to, the problem lies with the television.

  • Inspect the cable connection. Oftentimes when connecting a computer to an LCD TV, you can have strange dark streaks across the screen. Use a DVI-to-HDMI cable connection when plugging in your computer, then press the "Menu" button on your TV remote, select "Picture" and chose "Square Pixel." See whether the image adjusts and the dark streak goes away.
  • Contact the manufacturer of your LCD television if the dark streak remains. This streak can be caused by a defect in the television; if the TV is still under warranty, you can have it replaced.

    Got a couple of dark streaks on my flat screen. More prominent in extreme dark scenes and light scenes


    you will want to go into your tvs setting and restore factory defaults using the user manual if after doing this your still getting the dark streaks the television may need a new board. The cost of a new board and labor is usually cheaper than buying a new tv but if its still under warranty or you still have the receipt I would suggest returning it to avoid the headache

    How do you take a picture of a fast movement?


    It depends on the effect you want.
    • To freeze motion, you need either a fast shutter speed, or a fast flash in a dark environment. In less than bright light you may not be able to get a fast enough shutter speed to stop the action. Increasing the camera's sensitivity to light by increasing the ISO will help some.
    • You can blur the motion by using a slower shutter speed and a stable camera. Set a slow shutter speed and put the camera on a tripod or other stable surface, and you can get things like streaking car taillights and star trails. How slow a shutter speed depends on the speed of the subject.
    • You can pan with the subject. Move the camera with the subject, and keep it moving even while the display blanks out while taking the picture. This will keep the subject sharper while blurring the background to lend a sense of motion to the picture.
    • It's either to freeze motion if the subject is moving straight toward or away from you than if it's moving across your field of vision.

    Copies too dark


    Hi Scottie,
    Please clarify if the darkness is like a darkened background or like streaks across the page... If it is the former you will just require a clean of the optics, if the later then a drum cleaning blade will probably do the trick...

    Please let me know if I can help further johno@execs.com .

    Exposure control options


    The following exposure options are available: P (Program auto), A (Aperture priority), S (Shutter priority), and M (Manual). There are four scene programs modes available in which the camera will choose the optimal settings for the picture: Landscape: Suitable for taking photos of landscapes and other outdoor scenes. Both the foreground and the background are in focus. Since blues and greens are reproduced vividly in this mode, the landscape mode is excellent for shooting natural scenery. Portrait: Suitable for shooting a portrait-style image of a person. This mode features an in-focus subject against a blurred background. Sports: Suitable for capturing fast-moving action such as sports scene or moving vehicles without blurring. Night scene: Suitable for taking night scene photos with a slower shutter speed.
