Most projector lamps last approximately one thousand hours. Other possiblity might be the filter that has darkened due to heat.

I have a Kodak Ektagraphic with no model listed on it at all. How can I find a replacement bulb, all I can find look wrong.


Supplied with 82V, 300W EXR lamp Projection Lamps Quartz-halogen 82 V projection lamps- Here is service manual link http://resources.kodak.com/support/pdf/en/manuals/slideProj/manual/ektagraphic_sm.pdf Several different Models all say EXR 300W As CORRECT Bulb : EXR, 300 W (35-hour lamp life at full lamp/medium-brightness) Sampling of other lamps: EXY (200 hours/less brightness) EXW (15 hours/maximum brightness) FHS (70 hours/medium brightness) Use combinations of lamp brightness, plus half- and full-lamp settings to approximate image brightness in multi-projector presentations. Lamp Tips • Projector operation on line voltages above 125 volts greatly reduces the lamp life. • Unplug the projector before changing the lamp. • Allow for unrestricted flow of air to the exhaust vent to prolong lamp life. • Gently wipe off any fingerprints with a soft cloth moistened with rubbing alcohol.

The image is very dim, even on maximum brightness. We are considering replacing the bulb, but bulbs for this projector are very expensive and we suspect that since there is some image, the bulb is not the...


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.

I replaces my bulb in the sony vpl-hs10 and it still will not turn on after I reset it what do I do now? the lamp light is still lite it turns on but the lamp does not project anything


These instructions are for a Sony Cineza VPL HS3, but may be the same for the HS3.
1st thing to check - is the cover properly/completely closed - this can stop the projector from working.
Connect the power and set the projector to standby mode.
Press these buttons on the remote control in this order, for less than 5 seconds each.
Reset - Left Arrow - Right Arrow - Enter

This is required, to reset the lamp timer.

Also, something I found interesting from the internet - lamp life isn't when the bulb dies, but when a bulb has lost 10% of its brightness - so you might well be able to reset the timer and get much more use from the bulb - the image just wont be as bright.

Optoma EP732H Projector - Image is Whitewashed


Hi tourblack

I wouldn't think that this is a lamp issue , as the lamp will make the picture fade away in brightness and wouldn't look white washed.

Check if the brightness is set to 50% and the contrast on 50% as well.

This could be a colourwheel that is in need of replacement.

The bulb won't do that. What you're describing sounds like a light tunnel failure.

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
