    I use it with my laptop as well as the dvd.  both have monochrome setting.  The projector is used in church settings. We changed the lamp and now the color is gone.

It may not be an s video connection problem. it may be that your DVD (or video source) is set to a different color system other than what your projector is set to.

In your DVD, try pressing the NTSC/PAL button.

Good luck and kind regards.

    Hi again,

    Based on your post, I am assuming then that:
    1. The projector with either a DVD or a laptop was working fine before with the s-video connector;
    2. the monochrome issue came about when you replaced the lamp/bulb.
    Tech sense would dictate that you rechecked everything again: from how the lamp was removed, replaced, locked, covered, all surrounding components that might have been dislodged, moved or disconnected. It's just like doing the job all over again.

    If this does not resolve the issue, you may want to:
    1. Check that it is set at your country's color system. A BenQ PB8240 has 4 choices: NTSC, PAL, SECAM or YUV.
    2. Check that all your cables are snugly fitted and secured;
    3. Check that your DVD is set to the same color system;
    4. Check your mode settings, the BenQ has several: (PC/ DVI signal input only) Presentation Mode, Vivid Mode, Video Mode, Economic Mode and (YPbPr/ YCbCr/ S-Video/ Video signal input) Gaming Mode, Video Mode, Cinema Mode, Economic Mode
    4. Do a reset which returns all settings to the factory preset values.. With your remote, menu, control, reset. If you have your owners manual  with you, this is better explained at page 25

    Hope this be of help/idea. Post back how things turns up or should you need additional information.

My Infocus 4805 is just showing the INFOCUS logo and not showing the picture from the TV. all connections are correct but no

Powering On
  • If your InFocus 4805 projector is having a hard time powering on or doesn't power on at all, it could be one of two things. Due to the extreme temperature of the lamp that causes the temperature of the projector to rise, every InFocus 4805 projector has a cooling system. Check your projector's cooling solution, as it may need to be replaced. Also check the projector's fan---if the fan doesn't spin, the unit will not turn on. If the problem is the fan, you'll have to get it replaced. You can do this at the same place you bought your projector.
  • The Lamp
  • If your InFocus 4805 Projector powers on but does not project any light, the lamp will need to be replaced. All projector lamps must be replaced at some point---how often usually depends on how much use the device gets. Simply order a replacement lamp, unscrew the old one and screw the new one in. The projector will then work like new.
  • Color Wheel
  • If your InFocus 4805 projector powers on and is displaying images but the colors on the images appear warped or are not in the proper places, your "color wheel" will need to be replaced. The color wheel is a small device that essentially acts like a prism. Light is projected through it and it displays the appropriate colors on screen the way they appear in the original video source. Order a replacement color wheel that fits your model and use your instruction manual as a guide as you swap the old one out and put the new one in.

    I would suggest replacing the type of cable you are using. Changing the type of connection, such as S-Video or VGA or something other than what you are using, may resolve this issue as well. Because the splash screen comes up normal, this tells us that the issues lies not with the device but with whatever it is you are connecting it to. Comment back if this does not resolve the issue and we can move further.

    Good Luck,

    Model LC-SVGA 860 suddenly lost color, everything is monochrome.

    If it is a DLP type projector and not an LCD, then you've broken your colour wheel. I would recommend professional replacement as it can be a bit fiddly and you need to source an exact genuine part.

    Thin vertical line appears on projector

    I have found that vertical lines that suddenly appear from projectors are due to poorly connected cables. Sut off your projector and wait for the fan to go off. Then unplug the connectors from the computer to the projector and secure them again, making sure to go all the way. Hope this helps.

    Colour picture just went off

    Hi biga63

    I trust that you used the normal Video ( Composite ) Cable while viewing movies ?

    Have you tried using another Composite cable ?

    When using the S-Video - press the Source button on either your remote or Projector - untill you get to S-video.

    If it still doesn't respond I'm afraid your Mainboard has a fault on it and will have to be repaired by a technician.

    Blue colour spread

    1. Reset the projector to factory defaults,Change sources. Try plugging the projector into another computer.If the color problem persists, check the cables for bent or broken pins. If any pins are damaged, the cable will need to be replaced with an InFocus-approved cable.
    2. Upgrade the projector firmware. If the projector still will not display the image, it is possible that there is an internal problem that requires repair.
