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.

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 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.

LP70 lamp will cycle on and off in 3 min. intervals.


go into the menu and check the lamp hours. if it's over 2000, you need to replace the lamp. if it isn't, the power supply and/or ballast is starting to fail.

it's chirping because it's trying to keep in sync with the dmd chip. for the refresh rate, go into the menu and first reset the settings to factory default. if this doesn't clear it up, try matching the signal.

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.

Lp70 projector Error message about Fans


I had a similar problem with an LP70. my fan was sticking.
So I opened bottom cover and pulled out fan cage, there are 2 fans.
you must know which fan not running.
If you found bad one remove paper label(yellow)
you can see 3 small holes.
using wd40 few drops to holes.
then manually turn using your finger cw and ccw few times
you can feel smooth turning now.
then relabeling to hole side.
reassemble unit.
power on.
Now you can enjoy with your projector.
