SOURCE: focusing

Hi real12

Unfortunately you will have get the focus ring replaced before you will be to make use of it if your model doesn't have automatic zoom and focus in the user menu.

Sorry , but there simply is no other way.

SOURCE: Infocus LP 70 projects a blurred display

if it's pixelated, it's an electronic issue. if it's evenly blurred, it's an optic issue. was it dropped on the lens? see if the lens is hard to turn or is not sitting properly in the projector.

Epson projector center blurry


Sounds dumb on this one but make sure the lens is cleaned. Other then that check the manual for operating range of lens to screen. Typically somewhere in the area of 8 to 12 feet.

White spots on screen i have changed the lamp


It's probably you have a busted DMD chip, have your technician replace that, better yet buy a new projector because replacing that chip costs almost a brand new unit.

How do I clean the filter of the Hitachi CP-X1200 multimedia Projector ?


Remove and use fine bristle brushes assisted with a jet of air which will clean up the fine netting of the filter. It is important that the filters are occassionally cleaned so that there is no dirt accumulation within the lens unit that can reduce the life of the LAMP and save an expensive repair.

Cannot focus uniformly across the projected screen. This seems to be more than a focus problem in that some areas of the image seem blurry as opposed to out-of-focus. Also, in what may be a related...


try bringing the screen up as close as possible to the projector and still get a focused picture. check keystone here and also for image clarity. if you still have problems, check for dust or moisture etc in the optics. check the lamp for a clean front surface. clean the air filter also. Try a different image source for differences

Projected image is blurry, mostly at the top of half. Weird. Tried another laptop. Although that one was slightly clearer, the top of the image was still blury.


Clean the lens on the front, turn on the projector and wait for it to heat up, then turn the plastic ring on the front to change your focus. computer image can't be made blurry because of software. Blurriness is always something to do with the lens.

There are blueish-purple crystal-like distortions in the projected image. They actually can be brought into focus to look at, and at that point the projected image is extremely out of focus. So, obviously,...


either there is something on the inside of the lens, or there is something on the lcd prism face. if it was the lcd panel, it would be in focus with the picture. take it in for a good cleaning.

Projector produces very low light.


My recommendation is that since you have 2 of these machines and the other is working fine,

Pull out the lamp from the good one and place it in the faulty one.

Turn it on and check the projection quality if it is still blurry. If it is working good, then replace the lamp. If it is still blurry, a good cleaning to the lens on the projector may be a good idea.

You can also check the auto focus function of the projector and the cable that provides the video signal to the projector

You can get the manual from below link if you need to find out how to check the auto focus setting
