Lamp Fail

[guitarist155]

yep sounds like your bulb failed to me, just because it is rated for that many hours does not mean it will get that many and that amount is getting close enough i would say its the bulb

but would it work after unpluging it and re pluging it?

yeah it probably has a safe mode after it has done so many hours it will tell it the bulb need replacement i know some people have over used the bulb and had it blow up inside the projector. but i can't say for sure. if you can, i know my projector has a reset lamp hours setting where you can tell it you have a new bulb i would try this and if it works i would change the bulb soon after

well im having a guy i know who runs a hdtv store in my area order me a new lamp which i should get next friday. so ill try reseting the counter.


my projector should have a message that pops up saying the lamp is nearing the end of its life cycle but no such message has been see. so ill try reseting it and see what happens.

If your light engine failed, then you'd most likely see a distorted or discolored image of some sort. On the other hand, if you your lamp failed, then you'd have no image at all. Just a big black screen.

There are two reasons for lamp fail... the obvious one is that the lamp is indeed bad. All projo manufacturers warranty lamps for 90 days because they are after all, just light bulbs. One can last years... or seconds. You never know. Osram and Phillips make most of the lamps for DLP projos and one is not really any better than the other but make sure you get the correct lamp for the unit. There'll be quite a few that will fit but only one is made for that unit and there are reasons for that.

The other reason you'll get lamp fail is because of a bad PCB (power board). The formatter board could be bad as well but it's failing is not as common as the PCB. Ther fact that the lamp does come on periodically and then shuts down suggests the PCB. Usually, if the lamp is bad, it simply wont fire up at all. If it powers up and then down after a time and can do it every time you turn it on, it's likely the PCB. That's not major surgery but will require a tech to do it.
The most common reasons why lamps have short life spans are: too many power ups and downs in an average day. If you turn it off for a hour or two then turn it back on, it's better to actually leave it on during that hour or two. The other reason is heat. If the unit can't breathe right, it'll fry the lamp. Get a UPS hooked up to the unit so tht if you have a power failure, you can shut off the lamp and let the fan cool it down rather than let it cook which drags the life down massively. Hope that helps you a bit.

i would say it is probably your lamp, ether that or the thing that tells you its the lamp but with that many hours i would say there is a good chance the the bulb has failed prematurely
