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.

    InFocus ScreenPlay 4805 no projection. Unit powers on and green light blinks, but no light and no fan, eventually red light blinks continuously about 2 seconds between blinks. When the green light is...


    the high-pitched sound is the colorwheel trying to spin up to speed. that may need to be replaced. check the inside of the lamp for bulges, black spots, fogging or flaking. if it has any of those, replace the lamp. you can get parts from an infocus service center or send it to them for repair. either way, try www.avsolutionsny.com they're really good. if you want to replace it yourself, there is a detailed step-by-step on my "tips" area. it's the same as the infocus x1, x2, x3 and sp4805. click on my picture and scroll down to tips. good luck!

    How do i find out if i need a new lamp for my infocus 4805. when i turn it on the fan blows for a cpl secs and the green light blinks a few times, but i dont get anything saying the lampis out


    when you power it on, do you hear a high-pitched whir? if not, you need to replace the colorwheel. it's also the colorwheel if you hear a buzzing instead. if the colorwheel does not spin, the lamp won't come on. if the colorwheel is ok, check the lamp. is the screen on the side of the lamp clogged with dust? is the inside of the lamp bulging, spotted, or foggy? if so, replace the lamp and clean out your projector with canned air. dust blocks air flow and keeps in the heat. this shortens the life of your lamp and projector. if you do need the colorwheel replaced, you could get the part from an infocus service center and do it yourself, or send it in for repair. either way, try av solutions in ny. they're really good. www.avsolutionsny.com

    In the manual there is a chart which will indicate the nature of the failure depending on the number of times the red led flashes before a pause.

    Most common is the projector's lamp timer has exceeded the operational lamp time limit.

    While the projector's red led is flashing, press the volume up and down buttons on the projector simultaneously and hold them both in for 10 seconds.
    This will reset the lamp inhibit protocol.

    However if the lamp has thousands of hours of use you need to replace it before it actually fails.

    I turn on the 4805,green led blinks & bulb does not come on?


    After a few minuets does the green blinking light turn to a red blinking light?

    If so the problem is the lamp did not strike.Either the lamp has failed (most likely) or there is a problem with the power supply (less likely)

    Infocus 4805 blinking red light problem


    My first questions is:

    Is this the first lamp you have placed into your Infocus pj? If not, did you reset the hours when you did it last time? Otherwise that can also confuse the projectors internal system thinking there is NOT a new lamp in there and there for make it stop working once the clock hours are expired and over the 3000-6000 suggested hour life.

    Let me know so I can help trouble shoot other possible problems.
