My X1 just went south after 265 hrs on it. I think it's the bulb as the picture went very dark for about 20 min. then the unit shut down completely...bummer. Is that what happens when a bulb goes?


Also, I wonder what the best way is to shut it down? With the remote which runs the fan for a while or a hard shut down with the switch on the X1?


Thanks.

I shut it down with the remote and when the fan goes to low speed (after a minute or so), I hard shut it down.


I started a thread about this a few weeks ago and got lots of different opinions.


I don't use the switch on the X1 to shut it down, though. I bought a set of wireless power outlets with a central control (next to the sofa) to turn on/off the X1 and the lights remotely.

So the fan stays on 24/7? Do you have to clean the filter often?

I have seen more than one thread asking about the proper way to shut down the X1. And the same answer was given in all of them.


I shut down my X1 exactly the way Bob Williams from Infocus says. A hard shut down. It is best to let the bulb cool on its own. That is unless you plan on turning it back on soon.


Bottom line (at least for me), Bob is the expert on the X1 and I do and will do in the future what he recommends.

So what exactly is a "hard shutdown" ? I would rather do it the way it is supposed to be done.


Thanks

At 1st I was doing a hard shut down via the main switch. After mounting it up on the back wall it became inconvenient, so I started using the remote with the fan running a while before shutting down.


What is up with the standby light always on? Do the circuits stay hot?


Thanks.

Interesting that people advised "hard shutdown" which means cutting the power off from the PJ disallowing the cooling fan to cool the PJ after use. The theory is natural cooling the bulb is better than speed cooling of the fan. The reason PJ maker use cooling fan after "soft shutdown" is to allow restart sooner for presentation in the classroom. Restart on a hot bulb is very bad supposedly. I personally use the "soft shutdown" in case I get the itch to fire the PJ back up later. I usually wait 1 hour before firing the PJ back up if it was just turned off. Like the light bulb in your house, bulbs can burn out before its rated hours. This is painful and expensive but it's reality with bulb-based front projection.

But, only 265hrs.? What up with the 4,000 hr. lamp rating. Is that only true in a vacuum...like in the International Space Station?

It's hard to believe 265 hrs bulb life directly relates to your shut down method. I'd just say you got a lemon. How many hours were the lamp warranty? You should probably call Infocus to try to get a discount on the replacement lamp.

No one said it directly relates and the unit is under warranty. Thanks for your valuable input...

I guess I will start shutting mine down via the switch if I plan on leaving it off for more than an hour or so.


One thing I have been concerned about is the fact that I have left my unit running for 8+ hours at a time. Does anyone know if this is not recommended?

Hey Ace5000....


I noticed that you said you mounted on the back wall. Is it sitting on a shelf or hanging in "free space"...ie. with a "right angle bracket"... much like a ceiling mount but off the wall instead. If is sitting on a shelf (or under the shelf for that matter), you might want to check to make sure that there is "adequate" air flow... if it is like "normal" shelfs, both the bottom and back would be "restrictive" not leaving much room for air flow. I have about 400 hours on my unit... doesn't mean anything but I am sure there are currently alot of people with over 1000 hours on their. Ultimately, I would probably think you were unlucky with the bulb...:-( Having said that, I have seen a number of threads from various projectors that seem to have a "~400 hundred hour" fatality domain.

Very good deduction budwich. I'm sorry to say it was not heat build-up due to inadequate ventilation. It is hanging down on the bottom of a wire mesh shelf, unencumbered.


One thing though, I have had a habit of leaving the thing on like all day and half the night on some weekends to watch TV and movies. I also ran it on weekday evenings for TV as well, as it became my primary "tube." At 4,000 hrs. rating, what's the difference I thought.


Does it matter to the point of not being able to take the constant heat of being left on? Is that it?


Thanks.

Hey Ace5000...


That's a good question about continuous run time... again some of the post in a couple other discussions indicate that some unit (not X1s AFAIK) end up with significant "body heat" to the point where they are "hot" to touch. You might want to see if yours is anything like that (I doubt it). I have run mine for about 6 hours straight and although it is warm, I would say it isn't hot to touch. On your mesh shelf, its probably good but I have noticed on things like screen windows that the screen mesh does act somewhat like a "dead air" barrier... my gazebo outside is like this. Even though it is windy, the inside is almost still. Again, just a thought. I would still guess a bad bulb.

The longest i've had my X1 on for (only had it 4 days) is around 5 hours and it seemed no hotter than after 30min.


I shut it down via remote due to simplicity.


Mates Phillips PJ is 3+years old on original bulb with over 4000hrs and has ALWAYS been shut down with remote and it has 3min fan. Totally different PJ i know, but still.
