Hi, I have a Infocus Projector, Model # LP70, serial # begins with ACAN. The projector only has 951 hours on the bulb. The unit powers on and I get the Infocus startup screen. as soon as I turn on a video...


I think it is the time to remove the cover and check for air filters blocked with dust.
When this happens, air doesn't flow freely through the projector and result in overheating, which leads to automatic shutdown.

InFocus LP70 keeps shutting off


if the fans go off imediately too, it's the power supply. if the fans stay on, it's either the lamop, ballast, or colorwheel. either way, you may need to send it in to an infocus service center. try av solutions in ny. they're really good. www.avsolutionsny.com

Wont light up


the colorwheel needs replacing. if the colorwheel won't spin, the lamp won't light. if you hear a high-pitched whir, the colorwheel works, which means there is a power supply issue. there is a fix for that, but you have to be good at soldering. if you are give it a try: http://www.infocus.com/service/asc/communications/tech_notes/2006/09/tn495g.pdf

InFocus LP70 projector is running hot


clean the dust out of it with canned air. the dust keeps in the heat that the projector is trying to expell. it also shortens the life of the lamp.

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 LP70 color problem


try resetting the settings to factory default through the menu. if there's still a problem, take the cover off. if you look from the back of the machine, inside on the bottom left, you'll see the main board attached by a large white plug. use something thin and non-metalic to push the bottom of the board towards the plug to tighten it. now do the same to the other side of the plug. this should solve it. if it doesn't, you need to replace the main board.

Cannot see computer displyed on output of infocus screen shot


Many laptop computers do not automatically turn on their external
video port when a projector is connected. On many laptops, the activation function key is labeled with an icon or the text CRT/LCD.

Try the Function Key with the Icon of a monitor to enable the external video port.

If that does work, look at the settings on the projector using the buttons on the top.

Check the "Default Source"

Default Source toggles among Computer 1 analog, Computer 1 digital, Computer 2, and Video. This determines which source the
projector checks first for active video during power-up. Highlight
Default Source and click the left or right mouse button to toggle
among the options.
