(old) InFocus LP335 Projector - powers on for 1.5 minutes, then dies

I recently had my boss walk into my office and set an InFocus LP335 projector on my desk and tell me "it doesn't work" no explanation, no in depth complaint. I set it up and face it against the wall and power it up. It turns on, finds a a signal and is fine. for 86 seconds. the problem has repeated itself many times, and i went ahead and pulled the fans and vents and dusted them thoroughly. I've never really worked on a projector and know the basics, but not much. Any help would be great,

Thanks!

    REVISION: Im sorry, maybe I wasn't clear by accident. it powers on for 86 seconds and then it dies, and will not start even if I let it sit for a half hour. Any Help?

    I have exactly the same problem. I'm thinking about an overheating problem, but all the fans to work well.

    If you were able to fix it, can you tell me how ?

    Thanks !

I recently replaced my bulb on my Cinego Projector, all the fans work - the light on the top works, but no light on the projector screen.

Can someone tell me what can be wrong?

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.

    After having the projector on for 15-20 minutes the lamp will go out for 1-2 minutes then turn back on with no intervention This will repeat at no set intervals. The projector is not quite 5 years old...


    The ambient temperature in the room is to high.
    Try lowering the room temperature. If that doesn't work
    get a small fan and place it near the projector to provide
    extra cooling. The projector is running border line on
    high temperature and just needs a little extra cooling.

    Lots of details: LP120 stays on for a minute, then powers off


    either the colorwheel motor is not getting up to speed to sync with the dmd chip, the wheel sensor is going, or the power supply needs replacing. you can try to replace them yourself or send it to an infocus authorized service center. try www.avsolutionsny.com . they're pretty good.

    InFocus LP70


    Have you tried another lamp? Sometimes thats your problem, but I've seen a several occasions that the a defective power supply causes this symptom. Do you see an image flicker before the projector shutsdown? I do have some spare parts for this projector.

    I'm on Ebay - gtitubro if you want to contact me through there.

    Infocus IN72 Projector. NO POWER OR NOT POWERING UP


    This model projector is very sensitive to internal heat. I f by some reason the projector was abruptly powered down without the use of its normal procedure, in other words, unpluging cord from wall while on or power outage in premises, then the heat remains trapped and the sensors overheat and subsequently shuts down the unit. Now, although, once the sensors cool down it should reinstate operation some sensors become permanently damaged due to the extreme heat. In this case without having more facts, i believe it is the cause. I recommend a free check up to your nearest shop, most shops will offer free check ups.

    Lp335 in focus projector lamp not turning on; spark switch gap is sparking


    It could be the lamp. I have seen this many times on DLP'S. If the ballast is firing it which is usually around 600 volts or so, then i would say it is fine, and only needs a lamp. Let me know if that helped you. Later Jay
