[b]Background[/b]: I got a great deal on a (very slightly) used Infocus IN38 nearly a year ago... it had only one hour on the lamp, and has worked great from then til now. I use it as home theater and home office (my home office PC became the HTPC ,and I didn't mind a 120" diagonal screen for my work or my play). I was up to 800 hours last I checked, probably close to or over 1000 hours though.
[b]Situation[/b]: Today I got home from a vacation, was gone for 6 days and the projector was unplugged while I was gone. I turned on the PC, plugged in the projector which auto powered up (as usual when first plugged in), and I was off and running as usual. Thinking back I am not sure if I heard the projector fan come on, or only the power chime...it is very faint anyway and I tend to drown it out.
Half an hour or less goes by and I hear a loud cracking/popping sound from the projector, the screen goes red monochrome and then slowly fades/dies. Looking at the projector, the lamp light is on, and the fan is not running at this point. I wait a minute, and the fan is still not running, so I unplug it, go get the ladder and pull it down from the ceiling mount. I am a bit miffed as I figure it means buying a replacement lamp, which I kept intending to get a spare on hand but neglected to do (and can't afford at the moment :().
I open up the lamp cover and the heat just billows out of the unit, I can see a slight mirage at first from the wave coming out. I unscrew and quickly pull out the lamp unit, burning my fingers in the process, and set it down to look over. It seems to look fine. I have no idea what a burned out projector lamp looks like, but it is clear with no burn marks, and the wires all seem fully attached inside and out. It looks nothing like a burned out light bulb.
I then pick up the projector to move it to a safer location, and hear pieces of something rattle as I flipped it from upside down (as it was mounted to the ceiling and as I had laid it down to remove the lamp) to right side up. Finding this odd, I picked it up and slowly rocked the unit from one side to the other, and was treated to sounds of broken glass (I think) rattling in the unit. I reopened the lamp cover, and tried to see any loose bits, can't see anything. Looked through every crack I could without removing screws, and can't see anything. But something is rattling around in there.
Is there any way to know what is going on without me voiding the possible warranty (previous owner had never registered it so I registered as if a new purchase, just not sure how long I have left on it or if it is up), and without buying a replacement lamp (can't afford to for at least a few weeks :()?
I am particularly disturbed by the facts that the screen went red and stayed that way a good 10-30 seconds before fading to black (not solid red, just monochrome - the same image was up, but all in shades of red), and the lamp looks fine to me, and there is something rattling around inside.
Please tell me it is just coincidence, everything is fine, and I only need to wait until I can afford a new lamp! |

I recently got a projector for a steal - 3 hours of lamp life with no lamp hours reset, plus extras and such, for less than a quarter of the price it should have been going for (even used).
In the past 2 months or so, I have put 350 hours on the projector, as I am using it for my primary work PC which is now my HTPC as well. (It was a huge adjustment to move my office to the living room, and I still am hoping to afford another PC to get back into my office, but that is beside the point).
I find I am constantly leaving the computer for 5-10 minutes at a time, sometimes 20 or 30 minutes. I have been turning the projector off each and every time I think I will be gone for more than even one minute, in an effort to conserve the lamp hours.
But then it occurred to me that turning it off and back on so much may be just as bad or worse for the lamp life.
Does anyone know which is better for sure? If not, what educated guesses can you provide to help me decide if I will start to leave it on more often than not? How long of a break would warrant turning the projector off?
Thanks! |
