Can't reset lamp

even technicians who are familiar with those units, before installing new lamps, they use a 'calibration unit' for that or any particular model lamp and calibrate them right after installation. If you don't have the proper calibrator and adjust them right after you installed them, you will get that result. Even experience techs come across that problem if the calibration is not done properly. Also, each lamp for a different color value, has its own calibration/sync values.

bjac,

You are correct about lamps working or not, but that is the extremes. Over the course of operation all lamps lose brightness as the hours add up. All lamps will lose their brightness over time.

Typically lamps only last at best 6000 to 8000 hours. That is not long if the unit is used most of the day everyday. In addition the cheaper the quality of the lamp, cost and manufacture, the quicker they go down hill.

Assuming that you have a low quality lamp what you are experiencing is normal. You may be able to improve the brightness and clarity of the picture by cleaning the lenses, mirrors and screen. I have a tip at

This tip is labeled projection tv but is also appropriate for cleaning an LCD or DLP unit.

Thanks for using FixYa and for the great rating.

You CAN reset the lamp hours. It is surprisingly easy.

Hold UP on the projector until the lamp hours appear. Then press left or right to reset.

This took me a while to find! But it's in the service manual.

Hello,

I think this is a lamp issue. Even though your lamp might have an advertised time of 3000 hrs from Dell, it can fail and dim a lot earlier than that. Often within 1000 hrs a projector lamp's brightness can be reduced by up to 40%. Projector lamps brightness and lamp life varies according to how you use your projector and the environment it is in. Our company sells projector lamps and has created a YouTube video to help people get the most out of their projector lamps. You can see the video below. If you decide to buy a new lamp we have the lamp you need in stock at Projector Lamp Experts.

Hope this helps..

OK, that explains it. The bulb you have installed in the projector might be the original bulb that came with the projecoter when it was new. Just becuase it states 334 hours does not mean it is new. In fact, you could have a original bulb with 3000 hrs and reset the hour timer on the projector, which means your 3000 hour bulb might have 3334 hours on it because the person who owned it before you, reset the hour timer.. Best bet, buy a new bulb and reset the hour meter and see what happens. If you have the same problem, then your ballest might needs to be replace which is rare...

that sounds like a typican lamp going out.. (needs a lamp every 3000-6000 hours of viewing)
this is your lamp part number. if you have any questions about installing the lamp contact fixya chat

the projector will not know that u have replaced the lamp!u will have to tell it that a new lamp has been installed
to do this go to the menu & find reset lamp hours option & do a lampo reset.the lamp hours will reset to zero & then the replace lamp message will nt appear!

you need to reset your lamp hours timer. as far as i know this can only be done with the service remote

hold the volume up/down in ,switch unit on while holding these in for 30 secs, if that fails, flash unit with new software.
