InFocus LP70+ condensation/smudge INSIDE of lense

Any ideas on how to clean the INSIDE of the lense on an InFocus LP70+ to get rid of condensation? i can see that the condensation is on the inside of the lense and cleaning the outside has no impact.  I end up with a projected image that has a soft focus or halo around it. There must be some way to remove the barrel lense and get in there! Thanks!

    Very similar but with a Epson Cinema 6100. Manual says it should go way but it doesn't.

There is, but it is a pain. you need to remove the top, the cables off of the main board, the 3 screws on the main board, the spacers on the dvi connector, the rear screen (by it's screw), the fan underneath the board, the colorwheel guard, the 3 screws holding in the optical engine, then the optical engine. now you can remove the 3 screws for the lens and remove the lens. now if you can remember the spacing on the focus/zoom rings, remove the screws and unscrew the lens barrel and clean it. now put it back together. it might be easier to find another used lp70+ and swap out the parts.

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

if you don't hear a high-pitched whir, your colorwheel needs replacing. you can remove the lamp and see the colorwheel inside (colored glass wheel). if you turn it on without the lamp, the colorwheel should still spin. if it does, you have a ballast problem. if not, the colorwheel. you'd still need to send it in to an infocus authorized service center. try av solutions in ny. they're pretty good.

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.

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.

InFocus LP70 Won't display Top 3/4 of screen even with new bulb


if the colorwheel stopped spinning, the projector would shut off. take the lamp out and spin the colorwheel (with a pencil eraser) to the clear section and look at the square on the other side. if it's not a complete square or something is inside the square, your light tunnel is collapsing and needs replacement (also called an integrator rod).

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.
