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.

Lamp hour reset NEC MT1060


The NEC MT1060 lamp hours is stored in an EEPROM chip built into the lamp. As soon as you put in a new lamp (MT60LP or MT60LPS), the hours will be reset. If you remove and put back in an old lamp, the unit will see the hours on that lamp. Thus if the lamp has reached 2100 hours, the projector will remain in standby. See page 53 of the manual for the replacement and reset information.

Most of the manuals for the NEC projectors are available here: http://www.nec-display.com/dl/en/pj_manual/lineup.html . The direct link to the manual for the MT1060 is http://www.nec-display.com/dl/en/pj_manual/mt1065.html .

I hope this helps.

We use NEC MT1065 and just replace its lamp but it still won't switched on (lamp indicator led is red). How can I reset it ?


Hello, unfortunately the NEC MT1060 - MT1070 series projectors have EEPROM chips built into the lamp housing which counts the hours that the lamp has been used for so the only way to reset the hours is to change the lamp for a new one, if your old lamp has only had the reflector replaced then it will make no differance because the chip tells the projector weather or not to power up depending on the hours its counted, i have not yet found a way to reset the chips even by reprogramming them, i'm afraid the only solution is to replace the lamp with an official NEC unit, but this was obviously their intention, just as an added note, a solid red lamp indicator light means that the lamp has expired, if its flashing red this means its nearing the end of its life, if the status indicator light is flashing then there could be another issue, by counting the flashes you can reffer to the manual in the troubleshooting section to diagnose the fault, I know this is very late, but anyone else reading this may find it helpfull.

Nec vt670 projector , displays "the lamp has reached the end of its usable life.please replace the lamp" the lamp and filter are fine how do i over ride this error


Typically you will need to replace the lamp. Do not try and squeeze the last hour from the lamp as there is now a chance if the lamp will shatter and scratch the mirror and lcd block rendering your projector with a permanent scratch when projected. If you already have a new lamp fittted then simply go to the menu setting, under installation or setup by memory and there is a reset option.
