    Solved it! You need to hold the OK button on the remote and the OK button on the projector (not the menu button) and after 5 seconds the lamp reset dialog pops up. Why this is such a closely guarded secret I'll never know so spread the word!

Some possible reasons include: New lamp is generic and or has a issue----excessive dust or dirt inside the unit on fans etc.

Some of these units had a feature in the menu for quick on where lamp is lit at low level all the time---this shortens the life of the lamp etc

If you did not have this issue before lamp replaced I would suspect a generic cheap bulb may have been used instead of the Toshiba cartridge / lamp combo which costs more.

With the quick on if the set has it normal time is 20 seconds for screen to light----set WILL DETECT IF LAMP IS NOT COMING UP FAST ENOUGH OR BRIGHT ENOUGH.

Generic lamps (cheap) will never be as bright or last a long as a OEM lamp unit.

Just some thoughts based on your question.

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

https://www.fixya.com/support/r4690955-clean_lense_screen_in_projection_tv

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.

Yes, as bulbs age they will begin losing brightness. Most projectors have a bulb life hour clock, that measures the number of hours a bulb has been used. Usually you can pull that up within the menu of the projector. Also that particular model has what is called "Eco-Mode" and when engaged dims the bulb by 25% to cut down on power consumption.

Typical life for a lamp in that projector is:

3000 hours on Normal mode
6000 hours on Eco mode

You can expect a brightness loss of 50% when you are approaching end of a lamps life.

Whether or not you need to replace the lamp depends on how many hours of use it's had. You should be able to find the lamp time somewhere in the menu on the projector. Lamps for this projector are rated for 2000 hours (bright mode) or 3000 hours (Eco mode). In my experience they usually need changing at approx. 1500 to 1600 hours (bright mode). On Page 54 of the owners manual ( http://www.projectorcentral.com/pdf/projector_manual_4177.pdf ) are instructions for changing the lamp and zeroing the timer once it's changed. The lamp is Type number : DT00911. You should be able to get one from the manufacturer, the dealer you purchased the projector from, or specialty bulb and lamp stores. Be prepared. They aren't cheap, but it's better than having to buy a new projector.

Dell 3300 MP Projector


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..

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.

My picture brightness is uneven - there is a persistant bright field on my screen.


I have the exact same problem with my AE700. It a started about the same time, around 2500 hours for me. I lived with it untill I could afford a new bulb which arrived yesterday. The old bulb was still working at a 3603 hours when I installed the new one. But the new bulb didn't fix the problem for me either. I may try to take it apart this weekend and give it a good cleaning. Andy
