    When I say 'switch on' I mean at the wall, not on the proj' itsself.

I also had this issue - followed the On, Input, Undo, Left, Enter, Right, On button sequence several times. Then I decided to push them in that sequence very quickly and it worked. The lamp LED on the front changed to green and the projector started up. So the button sequence they provide in the manual works, you just have to push them in rapid succession. Hope that helps.

There is no problem here, the sharp projectors just do this until you enter the reset procedure. It comes on a sheet with your lamp. they differ from projector to projector. often involves hold down power and some arrows while plugging in the projector - that will reset the lamp timer and you will be away!

Or you could test it with just a burner which would be even cheaper. LumenArc sell burners individually. Your problem could be a ballast as well.

The bulb is trying to light but fails.
I would suggest you remove the bulb and check the connections are ok.
Make sure when you put it back it is in firmly.
Also while you are at it check and clean all the filters as they are often forgotten.

Epson PowerLite 410W projector (used for a smart board in a classroom) won't project anything or even turn on. Power button (maybe lamp indicator light? I don't really know anything about this...)...

It seems you assume that it is not an overheating problem.
The problem is, the bulb gets really, really hot when using the projector. It doesn't matter whether it has been there without any usage. As you switch it on, it will start to get hot.
But the lamp or other parts of the projector should not get too hot. To control the temperature, air is moved through the projector with the help of fans. Air enters through air filters and move through the projector absorbing heat from hot parts. This prevents these parts from getting overheated.
But what if air doesn't flow freely? Then the parts CAN get overheated.
First, switch on the projector and check whether you can hear the fans working.
Next, switch off the projector and remove power cable.
After about 30 minutes, remove the cover and check whether the air filters are blocked. If they are, clean them with a small brush.
This would probably solve your problem.

I'd recommend checking the fans of the projector, and make sure that they're spinning. Since you've mentioned that the lamp blew inside the unit, bits and pieces of the lamp might have lodged itself within the fans. It might also have to do w/ the after-market replacement bulb, which I normally wouldn't recommend.

Projector will not project light (Mitsubishi LVP-X80U) LCD Proje.

Hello toma_leonard,

First check your lamp to make sure it is seated properly in the socket.
Then check all of your interlocks (see your manual for locations), these are usually located on any hatches or doors that allow access to the lamp and or fan area. Once you check your interlocks make sure the filter and fan area is clear of dust, (some projectors have air flow sensors), and the recheck the interlocks. Once this is done , If the interlocks are not broken, or the lamp fuse blown, the projector should be working. If not it is the lamp that needs changing.

I know this may be expensive, however these lamps do go bad, as much as we wish they would not.

If you still feel it is not the lamp, have a technician check the voltage levels to the lamp and the levels of the control board circuitry.

I hope this helps,

Thank you,
