NEC LT260 Projector - Picture is dim - Not the lamp

My picture is dim. When taking the unit apart I noticed the wheel to have almost like a smoke film over it. I didn't touch it because I am afraid of ruining it. I looked online and could find no answers. I also haven't found parts for the unit. Can I clean it? Can you get new wheels? How hard are they to replace?

You can clean the film with dry cloth ..... but you must not expose it to light ....
and about the picture check & adjust in the settings the brightness,contrast,etc correctly ....
if previously the picture clarity was very good then i think the lens must have became weak ...
just visit the technician and get cleaned the lens of it ...

if you can do it yourself then you must clean the lens with the spirit or white petrol then reassemble it ...
if you are afraid or if you dont have any idea means then just visit technician and get cleaned the lens,any way it doesnt charge much

If You try to fix the wheel by cleaning it that will make it even worse. It is not hard to replace. Yes you can get new wheels at best buy and if not there radioshack might have them. I prefer best buy due to them having cheaper prices on them. If you have any more problems please let me know.

    please don't touch the image diaphragm as its sensitive. Use dry cotton fabric to clean. I also suggest you to perform full reset so settings will back to default

    We have 2 NEC LT260T Projectors, and neither of them will display anything! Usually, a blue screen is projected, but were not even getting the blue screen, or any light whatsoever. We turn on the power, the power light stays lit green, but the status light (green) blinks a few times, then the power light goes orange, and the status light blinks red. What's the problem with our units?

HD70 DLP Projector: The projector is used and about a year old. It cur...


Did this start occurring after you replaced the lamp?

The reason I ask is I had the same issue after changing the lamp and it was caused because when I took out the old lamp I noticed dust in the lamp housing which I attempted to blow away.

This caused the problem because some dust got further into the projector, specifically around the color wheel. I sorted it out by taking the projector apart following the instructions here:

http://tantht.blogspot.com/2009/02/how-to-remove-dust-blobs-from-optoma.html

(note my HD70 was out of warranty, if yours is not, I would recommend contacting Optoma to get it fixed).

Follow the above instructions to step 14 and then locate the color wheel which is at the front of the projector behind a dark gray, plastic type square shaped cover.

You have to be very careful here, but remove the color wheel (there is one screw holding it in place) - note it

NEC VT 480, replaced new lamp ,still low brightness.


if you remove the lamp, inside the lamp housing you will see a refraction (fly-eye) lens. these evenly distribute the lamp light. the one on the other side from the one you see (there are always 2 lenses) is probably burnt and needs replacing (a common problem with lcd projectors). you will have to send it in to nec. in many of their projectors, both lenses are in one assembly.

Sometimes the NP50 lamp will come on, sometimes it won't. Sometimes it seems like the color out-put isn't sharp or correct, like a faded picture. It's like something is wrong with the color. So it seems...


projectors really don't like hot and humid. they love cool and dry. if the colorwheel is failing, the lamp wouldn't come on. humidity+dust+intense lamp heat=coated components. such as the colorwheel glass, which is clear and coloered. fried dust will cause dimness. you'd have to send it in to nec.

NEC LT260's shutting down


I think I have solved this issue with my LT260K. I too had shut downs after 5 minutes of operation. It roughly followed a replacement of the bulb. I repaired stereos in the 70's and 80's, so I was not going to let the projector get the best of me without a tear down. I cleaned the fan blades, checked their operation. I checked the continuity of the thermostat on top of the bulb bracket, but found no apparent failures. I did find a possible loose connector in the middle of the projector as it seemed loose as I was disassembling the unit (see 1st picture). 7c58d4f.jpgThen I checked for cracked or burned areas on the PCB's. During this I scanned as much of the solder joints as I could. In the 'old' days, the power supply area could get hot and make cold solder joints. I found what appeared to be heat damaged solder joints on the auxiliary power board (Lamp power). This is the one that is back right of the projector opposite the power switch. It is a vertical board that solders into the horizontal bulb power board. I resoldered these and I am up and running. USE CAUTION, I would leave this to a trained professional to repair. This requires major disassembly.18d84c8.jpg

Nec picture turns megenta


I'm gonna take an educated guess and say this is a DLP projector. Sounds like the DLP wheel is slowing down causing blurriness and Magenta when the wheel stops. It probably needs a new color wheel. Call NEC and see if they have a bulletin or notice on this issue. If you're lucky, you might get a free new color wheel or replacement projector from them.

NEC LT260 PROJECTOR NOISE


To open this projector, you need to undo six screws at the underside of the case. That means you have to turn the projector upsidedown.
Pls note that one of these scews is a little hidden under the carrying handle.
After removing the screws, return the projector to it's normal 'up-side' up, standing position.
Remove the bulb cover srews and remove the bulb cover.
Lift up the top cover carefully starting from the front then all together.
The cooling fan is mounted very near the bulb assembly.
Carefully check the fan blades for any obtacles, wires or even a broken fan blade, that could be causing the noise.

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
