Out of focus

The projector is always out of focus. The screen display is off focus a bit . I have tried out all lens focal ring adjustments but can get to the right focus. No issue when the projector is new. Issue happened after 2 years of usage and it is now out of warranty.

I have an Infocus LP70. My question/problem is in regards to the lens. I dropped the projector from about a foot off the carpet and onto the lens. The focus/zoom became jammed together, AND the lens came...


What I would try to do is, loosen the screw so its not stiff to adjust, adjust the lens to the right position then tighten up the screw again. Hopefully this should work for you!!

THis is a very short throw even for a "short throw" lens. I would verify that this is the proper lens by its numbers and verify what you should be seeing by its tech specs (focal distance./image size to be expected)

Lens adjust is sticking. With the lense out you


since you have then lens out, get a wide blade flathead and insert it in the smallest part if **** that it will fit into behind the focus ring and turn the blade like you are trying to widen the **** all the way around until it pops out into it's normal position. Getting the entire lens back in properly is a bit tricky since the threads are easily stripped. First screw it all the way back on and then check the focus on the screen. You want to see a crisp image in 3 if not 4 of the outer corners of the screen. It is best to use something with text that fills the whole screen so you can see the 4 corners as you adjust the focus. If the focus is good in the corners, leave it alone. If not,hold the back of the projector in one hand and forcefully push the lens into where you screwed it on and see if it pops into place. It really is trial and error. Once you have a clear picture it is a good idea to remove the top cover and glue all around the base of the tube where it screws on so it doesn't come loose again.

How do i change the focus without the remote?


There ia always a ring around the lens of all optical devices. If you power on the projector and rotate this ring clock or anti clock wise then you will find that you are able to focus the device to the best of display. Else try the settings manually if there is a provision.

Focusing into slide transfer box


Yes, use a shorter projection lens. You didn't say what focal length your projection lens is, but Kodak and many of their OEM vendors made very short focal length lenses.
