I have a nec vt560 and the power light stays orange and the status light is off until buttons are pressed. bottom line is...i cant get the projector to come on...the power light never turns green.


The projector is in standby mode, which is a good sign.
When you press the ON button for "at least 2 seconds or more", what happens.

Do any lights come on at all?

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

The projector is an NEC model VT590 and is connected to my computer for use with a SMARTBoard. In the bottom left hand corner a pink colour is starting to grow inwards. In the upper left hand corner, there...


It is not the smartboard, lamp or the computer as well know, it's the projector itself. This may not work but you at least need to try press the auto adjust button on the projector and then adjust the clock/phase in the menu. If not you will need to send in to NEC it could by the color wheel. Usually they have a warranty for a couple of years.

How do you connect the NEC VT560 to project tv pictures


if you have a cable or sattelite box, or a tv with a video output, connect the video output from the box or tv to the video input on the projector. if you have a tv without a video out, you cannot watch tv and change the channels on the projector.

Dark horizontal bands appear on projection


Your matrix is failing. If the unit is under warranty, send it back.

The matrix is the bit that allows light to come through of each colour. If its failing one colour won't get through. If the circuitry is failing, more than one colour wont get through.

The left side of the screen is blueish?


The blue or yellow haze problem in this projector is because of two factors. 1) Dust buildup inside the optics and 2) Fading colour filters used in the internal optical process.

Inside the projector the white light from the lamp is split into three distinct colours of red, green and blue. Each colour illuminates their own monochrome LCD. Those LCDs are mounted on a prism that combines the separate images and displays the result you see via the lens.

The optical process to split the light up inside the projector is fairly complex and involves many light filters and mirrors to direct the light to the appropriate lcds. Those filters and lenses accumulate dust and also fade over time due to heat and other environmental factors.

I know that sharp sells replacement filters at $100 a piece. I do not know if Hitachi sells replacements.

To remove the dust and change filters you have to take apart the projector in a fairly complex way. I do not suggest that the average user do this. Good luck!

Panasonic PT-L701e - colour fault, blacks are blue with lines


Can you connect a computer (vga) signal to this projector? I'd like to know what your "white" computer screen does on the projector....example, Excel spreadsheet....

I am leaning towards these problems, a bad video card...or worse delamination of one of your LCD panels and possible polarizer burn in the optical engine.

Best Regards,
Steve

A DMD has no inherent colour capability - it's just a configurable mirror array. If you want to do full-colour projection, then, you'd expect that you'd have to use three DMDs and three coloured filters - red, green and blue.
But if a single DMD's switched in synchrony with a rotating "colour wheel" - a spinning tri-colour filter that lets through red, green and blue light in turn - then the very rapid switching speed of the DMD lets it lay down red, green and blue images in such fast succession that the result is a perfect colour image.
You can do the same trick with a single LCD panel, but it's not a good idea; LCDs are transmissive, rather than reflective, devices, and block something like half of the light that tries to get through them. To maximise brightness in LCD projectors, a three-panel design works better. If you try to pump the entire output of a super-bright lamp through one LCD, keeping it cool becomes rather challenging.
The extreme smallness of the moving parts on a DMD mean that it behaves like a solid state device, not a mechanical one. For all their complexity, DMDs have very high Mean Time Between Failures (MTBF), and well-made projectors based on DMDs can be expected to last easily as long as LCD units, and probably longer. If a DLP projector fails, it's not at all likely to be because there's something wrong with the DMD.

NEC MT800 Projector with Vertical Lines in picture


The ghosting problem is a combination of both the lcds and driver boards in which case neither need to be truely replaced.. They use a specific voltage to transmit data to the lcds.. Each lcd is different and the driver board is programmed by the factory for the EE v.com setting. Unfortunatly with nec, they do not offer a service mode to go in and adjust the ee settings to correct the electrical convergance. So the only way to fix the problem is to replace the lcd with a newer one who wasnt worn out from long term heat.
