Nec LT 240K projector

Hi! I hope that you will help me with the problem I have with this certain projector (NEC LT 240K). The problem is in the part where the lens is (with cameras it's called diaphragm, but i?m not sure if it's the same name for this particular part in projector). Anyway, this part has been somehow moved so that the picture is not projected through the center of the lens, but the picture is projected from the upper part of the lens. in order for picture to be normaly projected we have to put some books (or somekind of support) under the back part of the projector so that the projector is facing towards floor. I don't know if I explained it well, but the problem is definetly not software. When we look through the lens we see this "diaphragm" moved out of its place. i hope that you can help me or at least if you know how do we dismantle it! Please answer on my e-mail. Thank you in advance, Marina

The projector is not faulty, but rather designed to project an image in the way you describe.

This allows such projectors to be mounted on a ceiling (in offices etc). The manual (which can can be downloaded from NEC) shows this pictorially.

I have just acquired the LT260 which has the same off-centre iris.

In general you have to take off the lens and take it to a specialist who repairs gun scopes or binoculars. Me my self would not disassemble a lens unless I was perpaired to replace when it feel apart after removing screws Try calling them at 1-800-338-9549 or contacting www.infocus.com as they sell lens and projectors. Good Luck

Can I project vertically by changing projector orientation?

I have checked over the specs on a few different sites and ive found where a few people have stated that theyve used theirs in vertical position with no problems. If you are that worried you should be able to go to whatever program you are using and rotate the picture there also.

Cant clear lamp usage hours warning after replacing bulb on model NEC LT 157

Try holding the off button down for 20 seconds, it may be the on button. I had an NEC MT830 which had a standby function once it had reached and exceeded the lamp life safe limit. Once this had happened it wouldn't come out of stanby uinless the lamplife was reset. Your user manual should have the correct method of reset

Good luck, hope I was of assistance

Hi there! i have this nec mt1030g+ projector and its video hv sumthing like a copy of image with is like shadow of the real image in blue colour! i wanna know if its lamp fault or sumthng elsa! thanks

It sounds like a polarising lens has failed, if so it will probably be cheaper to buy a new NEC NP115 which has probably got the same if not better specification.

Hopefully I was of help to you

Security code for Nec lt260 multimedia projector

The menu and logo password are the only ones you can reset by yourself, if you lose your master password you must contact NEC to get the release code.

See page 113 on the manual :


NOTE: Do not forget your keyword. However, if you forget your keyword, NEC or your dealer will provide you with your Release Code.

After you call NEC and get the code do the following:

1. Press and hold the POWER button for a minimum of two seconds.
The projector will be turned on and display a message to the effect that
the projector is security-protected.
2. Select [Projector Options] → [Security] from the menu and press hte ENTER
button.
The Release Code input screen will be displayed as well as your Request
Code (24 alphanumeric characters).
3. Enter your Release Code in the Release Code Input screen.
The projector will turn on.
* If the projector is turned on by entering the Release Code, your Security
will be disabled.

find contact page from here or call the retailer:
