Projector bulb going out???? Acting funny??? (1 Viewer)

[Shawn Keeler]

I have a Integra DV-100 DLP Projector (basicly a NEC LT-150z). A few days ago I went down to watch a movie, fired up the projector and it came on, but it took forever for the bulb to warm up and display the picture. Ever since then it has been taking the same unusually long time to display the picture (somewhere between 4 to 5 minutes). Where before it took half the time. Any thoughts??? bulb going bad or what??? Let me know what you think.

It is possible that your bulb is exhibiting end-of-life symptoms but.... can you do a thorough cleaning of the filter and exhaust areas. On my PJ, that is about a 5 minute operation with the aid of some compressed air. BTW, what is the bulb life currently?

Here are the classic (as I've observed) symptoms of an old projector lamp.

1. Long time to first-light.
2. Slow build-up to real light.
3. Color takes a long time to stabilize.
4. Picture may 'flicker' from an unstable arc.
5. Pop! followed by the sounds of broken glass falling, getting ingested by fans, and the like.

#5 rarely happens; it is, however, something you want to avoid.

Another thing to remember is that the quoted lamp-life is generally the median lamp life. I, personally, have seen 1000 hour lamps last anywhere from 650 hours to 2400 hours.

Leo,
The problems you mentioned in your reply (except for the last one of course!!) are exactly what I am going through. So having said that, it looks like I am going to have to get a new lamp. Anybody now where I am get one. I have found a few online, but I can't seem to find one under $350.00. Anybody found one less expensive than that? Thanks, Shawn

That may be about the best you'll be able to do, unless you're a Not-For-Profit/Charitable/Government/Military organization (at which case your costs double, right?)


I don't know the specifics about your projector's lamp, but the number sounds about right.
