Infocus 4805 dead yet again! Need Help

I have the Infocus 4805 and first the light tunnel went then the color wheel. Now I don't know what the deal is. I remember seeing a post about a place where you can get refurbished 4805 for really cheap like in the $300 area. Does anyone know where that is? Thanks

I'm not sure. This is a much older projecter which came out around 2003-2005. It is hard to find any new ones otherwise they will be refurbished or used.

Have you contacted the manufacturer regarding a firmware upgrade for your pj? That can fix some errors some times. My sister/brother in laws both had the same pj and that fixed this issue.

Otherwise we do not sell any products on here we only suggest and offer solutions to errors or problems.


Good luck and let us know how things work out for you!

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.

    Need help looking for the part.


    Hi:

    Seems you broke the part called the color wheel assembly. Usually the color wheel can be replaced by you or a qualified TV servicer.

    New Problem after fixing Light Tunnel on a SP 4805


    It sounds like you have mounted the replacement light tunnel incorrectly. It is a common error. What has happened is you have the light tunnel sitting on yop of the positioning stop which is opposite from the color wheel side. If you take it back apart you will see that it's not laying parallel to the casting. if you reposition it so it is just touching where the opening is in the clamp on the color wheel side you will feel it fall into place.

    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.

    Glass prism


    Greetings,

    Thanks for contacting us regarding your product questions or concerns. It appears you are wanting to know how to reach the glass prism from your 4805?

    My initial question would be, why are you looking to access the glass prism in your 4805? This is a very dilicate process internally of your projector which helps it opperate. Are you trying to self-repair your projector?

    Let me know. I'll be waiting for your reply.

    Color wheel for a 4805


    I've encountered this same issue. I had a large Yellow Line down the left side of the screen for a few months. It got bigger and bigger, then one day I was using it and Bam! What sounded like a fire cracker was my color wheel exploding. I also had the rubbing sound, or at least something similar to that sound prior to the explosion. InFocus quoted me about $300 to fix..
