Bulb Shattered...After replacement does nothing!!!!!

Hello Guys,

My projector is seeming to have a problem. My brother was playing his video game on my projector when her heard a pop and saw the screen go out. After looking he saw that the bulb burst. We then went to a known working projector and took the bulb out of that one. After the replace the projector will not come on. No light screen at all. The green light on the cover will come on, you will hear the wheel spin for about 10 secs and stop. about 6 sec later it will try again. Can you please tell me what you think the problem might be. I would really like to get back to playing with my screen again...

If the lamp burst, then the projector should power up with a good lamp. Make sure it's properly plugged in and the lamp door is fully closed. Sometimes these models tend to refuse to power up and the led turns to red. Switch off from the power outlet for a few minutes and try again.

Make sure the plastic cover (the one you took off to replace the bulb) is closed. Closed fully!
On the plastic cover/door, there are 2 latches and one prong. Make sure the door closes fully, so that the prong hits a metal plate/trigger and "clicks". 
Once it clicks, the bulb activates and you get a picture.
Unfortunately, once I discovered that, the whole unit won't power on. That's right , absolutely no activity from the power switch.

I think you must be kidding. Based upon the current exchange rate, you are asking for a projector that costs between $49.00 and $81.00 USD. That's about half of what a projector BULB costs.

Owner of Sharp XV-Z10000 projector. Put in a replacement after market bulb with housing from Worked for literally 91 days and not much use. would not honor the warranty, of course. ...

Did you touch the bulb with your bare hands when replacing it? Should use a clean cloth of tissue to hold the bulb. Our hands have oil that might cause th bulb to overheat.
Some projectors need to reset the bulb counter in the machine. Check this procedure in the manual, to see whether it is required or not.
Another problem might be the air filter needs cleaning.

Picture has a yellow tint. It's from an old video game that ran over 12 hours a day. Has new bulb. Except for the yellow, works fine.

Hello there:
The best way to describe this is what is called screen burn in.
this is very common on screns that have games or pictures that arre displayed for long periods of time without being shut down just like on a computer screen when a screen saver is not used .
there is nothing wrong with the bulb.
the yellow that you are seeing is actually burned into the glass part of the projector and the lense
so if you can and feel like you can dissasemble the projector dissassemble it and locate the glass and see if you can get the yellow tint that will be on the glass and the lense off by using some rubbing alcohol and a cottomn swab
But if it wont come off you will have to replace the lense and the glass ok
Hope this is very helpful for you
Best regards Michael

I just replaced the bulb unit in my Toshiba TDP-MT800 projector but when I press the power button nothing happens

Make sure the Lamp is seated correctly and firmly and the microswitch on the lamp door closes. Some projectors require a button sequence to be held down whilst powering up the projector in order to reset the lamp counter and restart it. You could also try the old lamp back in it for a few minutes to see if it starts up using the old lamp, providing it hasn't shattered.
Good Luck

It makes a wierd noise

The bulb housing has come loose...

When the bulb heats up & cools in normal use, the housing will contract and become loose.

Unplug and re-seat the bulb and housing ...

Another possibility: If the replaced bulb shattered in the projector, there may be debris in the fan... use compressed air ($8/can RadioShack) to clean out (make sure the projector / bulb are cool before using compressed air.

Hope this helps!

INfocus X1 does nothing after bulb replacement

first off, make sur you have the right lamp (sp-lamp-009, 2 white wires. not the sp-lamp-018, one white, one red. the wires are in different locations in the plug). if you don't hear the colorwheel whirring, that'd be the next step. however, you cannot buy just the colorwheel. infocus does not sell individual parts of the optical engine. but that wouldn't matter, seeing as how they don't sell the engine anymore. also make sure the lamp door is completely closed. there is a peg on it that activates a switch to let the projector know it's closed. if you remove the lamp and use a flat-head screwdriver to activate that switch, turn on the projector. look inside the lamp housing and see if the colorwheel spins. if not, i think you need a new projector. if it does, check the fans. they can be replaced.
