Question about InFocus LP70+ Multimedia Projector
Lens adjust is sticking. With the lense out you can adjust it but it takes a bit of force to do. with the lens in it will not adjust, it just unthreads from the projector. I did lubricate the lens with some light oil on a q-tip and exercise it, this didn't help. any suggestions?
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.

force adjustments control the pressure used to open and close the
door. A new garage door opener from the factory is set to the lowest
possible force adjustment. If you have a properly balanced door, the
forces required to open and close the door should be minimal.
force adjustments are usually located on the rear of the garage door
opener and/or under one of the light lenses, If your opener has two
lights. If you have lights on the side of your opener, the force
adjustment will be located under the right light lens. The force
adjustments are labeled with an arrow indicating open or close and
numbered 1 to 9, with one being the lowest force and nine the
highest. The force adjustments can only turn 260 degrees, or ¾ of a
complete turn. Changes to the forces should be done in 10-degree
increments. Please remember that too much force will interfere with
the proper operation of the safety reversal system. Do not increase
the force beyond the minimum required to close the door. Do not use
the force adjustments to compensate for a sticking, binding, or
