Infocus 4805 blinking red light problem

My Infocus 4805 has stopped displaying the image. Its lamp looks good, only 560hrs.I have taken the lamp out and cleaned the filter. The color wheel also looks good. The fan is also rotating fine. The project tries few times to display the image and then the blinking green light turns into blinking red light. Please help. Cant figure what the problem. Can some one post pics of brunt lamp/color wheel so i can compare and see if my lamp or the color wheel is working fine or not.
Thank You.

    While watching a movie the picture suddenly cut out. I have only 300 or so hours on the bulb. when i try to turn it on it tries to start up 5 times but no picture comes up. Everything sounds like it is working. the lamp door is closed. the screens are clean, the color wheel is fine, the fans both turn just fine. After it tries to start up five times the red light starts blinking once every two seconds. I have no idea what is wrong with the projector.

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.

I have an infocus 4805 screenplay projector and i was using it when there was a pop and then i lost all color in my projector now its only black and white the bulb filter is clean what do i do.


Your projector is DLP technology. It employs a "color wheel" to provide colors other than blank/white. That "pop" you heard unfortunately may have been a malfunction of the color wheel mechanism, probably the motor. (It runs at very high RPM)

Sounds like you may have to find a shop to service your projector.

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.

    The picture suffers from colour fringing


    either the color wheel has lost a segment or the colorwheel index needs to be adjusted in the hidden menu using the color ramps test screen.

    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

    My InFocus 4805 SP projector is showing just black and white


    If you have any video at all and it's only Black and white there is a 99.99% chance that your Color Wheel has lost all of it's glass color filters.
    You can confirm this by removing the lamp. then look straight into the projector where the lamp was and you should see the color wheel of colored glass segments (Red, Green and blue) I believe you won't see them because they came off of the wheel.
    Also if you lift up the projector and turn it around in various angles and you will hear the small pieces of broken glass from the color wheel.
    Unfortunately you will need to take it to an authorized service center for repair. Be prepared to spend upwards of $300 for the repair.

    Cheers

    My Infocus DLP 4805 can't turn on


    very possible the lamp is bad. Many projectors will not even power on once the lamp burns out. As for the strange noise, there may be something more serious wrong with it.
