Last week while watching a Christmas movie our Sharp DT-100 shut down without warning right during
projection. Now when the projector is powered on the lamp attempts to
light, which it doesn't, so the lamp LED blinks (green) while it tries
to warm up. The LED goes solid for a second and then starts blinking
green again. This happens about twice before the unit shuts down,
illuminating both the lamp and power LEDs (red). I tried resetting the
bi-metallic fuse (breaker), but it wasn't tripped. This is when I
realized we had a problem. We have around 800
hrs on our lamp(not even close to 1/3 the spec life of the lamp). Any
help would be appreciated. I don't really want to drop over $300 for a
new lamp only to find out that doesn't fix it.

Flip over the projector with the bottom up to you. you will see a panel door front right of the lens. There is one screw to be removed from the lamp panel door. There will be two holding screws that hold the lamp housing in place, remove these. grab the handle and pull up towards you thus releasing the lamp housing assy. Then place the new lamp and firmly press down and then tighten the two screws that held the lamp assy, then replace the cover.
You will then need to reset the lamp timer. by pressing the menu+enter+the arrow button between the keystone and menu button simultaneously.
Here is how to replace a projector's bulb correctly :
1:Make sure that your power switch is off and that the power cord is unplugged from the electrical socket. It is also wise to unplug any other cables and label them in order to restore them in the right way once the lamp is replaced.
2:In order to see the lamp, remove the access handle on the outside cover. You may need to use a screwdriver.
3:Pull out the used lamp and clean the relevant parts using micro fiber products and not paper. Please note that in some projectors a small inside filter should also be replaced.
4:Insert the new lamp into the projector carefully avoiding touching the glass of the lamp itself. Touching the lamp will deposit skin oil that will likely damage any new lamp during use.
5:Reassemble the access panel, repluge the cables and power up the projector.
Things You'll Need:
new projector lamp
micro fiber duster
avoid touching the bare projector lamp
I hope this will help .
there are six screws in the base and two in the back of the unit. After taking off the top I saw a red button on the front that was a little pushed out - I pushed it in and I got the led lights back :)
The instruction manual says that to reset the timer you have to hold down (simultaneously) the Menu button, then Enter button and the Down arrow...then press the Standby/On button on the projector. This worked the first time I replaced the bulb, but now that I've had to replace it again, its not working. Good Luck.
Hi ThereNot sure what you visually describe as "blurry" This could be two things - a typical white screen will waste all the definition and brighteness unless you sit in a dark room Our ICE Digital Daytime Screens will take any projector and make the image up to 2000% brighter with a resolution reseolving ability of 20 million pixels.So in this case the definition you are alluding to could be lack of contrast, image definition due to insufficient light from the projector relative to the lux level of the room. Alternatively the lamp could be getting old. The brightness of a lamp falls off rapidly so as you use it more and more the image will become duller and duller contributing to a "blurry" or image lacking in punch etc. The technical lamp hour spec life is only a manufacturers "up to xxx hours" and not what you will achieve in actual life. If you want we are able to supply lamps as we ship internationally and also the same with our ICE Digital Daytime projection screens.Sharp DT-100 Lamp cost is $US261 delivered.

It is possible the lamp has died even though you only got 800 hours. Rated Lamp life is always up to and never a surety of those actual hours in the brochure will be acahieved. If you would like a quote for a replacement lamp let me know as we ship internationally. Regards Kevin Andreassend http://www.iceav.co.nz +0064-9-4142348 email@example.com
