Question about InFocus LP690 Projector, Factory Refurbished Multimedia Projector

LP690 projector displaying strange lines

I have an Infocus LP690 projector that is displaying lines down either side of the image. It appears to be something to do with the mirror or LCD alignment as the colours of the lines are red green and blue? The lines are roughly 2-3 inches wide and are more visible on the right hand side. This is from all sources. The bulb has used approx 350 hours and the areas unaffacted by the lines are crystal clear. However the whole image does appear to jump up and down slightly. THanks to all

To adjust those mirrors, you need to power down, unplug, remove the top, remove the wires from the main board, remove the main board, adjust one mirror, reinstall everything, power up, see whatever difference it made, power down and repeat until it's fixed. it's quite a chore. if that's not the problem, you'll need to replace the optical engine (which isn't cheap) because they don't sell individual parts.

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


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.

    First time using infocus 1x projector with this laptop - installed drivers but there is no start up screen on the projector and will not display laptop image.


    You have to tell the computer you hooked up an additional external monitor. Lower left on the keyboard you will see a "FN" key. Across the top, your F keys...look for an icon that looks like a monitor. Usually F5, F7 or F8. Hold down the FN key and select the F5 etc key which is the command to display the image through the external port. Doing this once displays image through the projector and laptop. Twice displays image to projector only and three times returns to display only on laptop again.

    Half inch crystal/ solid white vertical line on screen


    Adjust the horizontal in the menu then try the overscan adjustment. If the image does not look dim you do not need a lamp.

    The Infocus logo image is up-side-down even without connecting to the computer.


    Many projectors allow you to vertically flip the image for mounting the projectors upside down. Each projector is different in how to change that setting, so I would look in your owners manual.

    Hello i have a lp690 suddenly the picture dissapeared no ligt in the lamp..It has run 350hours only the power button flashes(green) but no alarm..Should the lamp be changed????


    you need to clean and resolder the edge connector on the power supply where it connects to the main board. on this series of prohector, this is a common problem. that and the yellowing of the image due to the frying of the light filter on the blue lcd panel (keep the projector clean and free of dust and you will avoid this, as there are no longer any parts available).

    Hello,
    It sounds like you may be feeding it with an HDMI source using an HDMI to M1-D adapter...

    If this is the case, make sure the source in not set to a resolution higher than 720p.
    However I really need more information to offer a definitive solution.

    Take Care!

    Image has bend at top of screen


    first reset the setting to factory default. if it persists on a regular image too, either the lens, the tunnel or something else in the optical engine is damaged (from a fall?).
