That's scary.
So far *knock on wood* in my humble 10 years I've never had a lamp blow in-service that wasn't a dud.
I wonder how many circuits don't change lamps at warranty.
It seems like it's always been the routine everywhere I've worked.
At Wallace I remember we had a policy about not running them past warranty hours, but it would take months to get a new lamp so if you had 2 go around the same time. You'd have to wait and see just which one ws in worse condition (they wouldn't order more than 1 of each size spare, we had 13 screens and it was a new install so all the lamps were close together for a while).

But I digress. If it's not flickering and not dim. I'll let it go for a while. Let's not get silly though. If it's in service more than a year, I'll probably swap it. No sense tempting fate THAT much.

P.S. I just had a horrible nightmare someone with a Film-Tech polo came to one of my locations and nothing was working properly [Eek!]
That was intense...

Thus, I'll catch them when they've got 10 or less hrs on them before warranty hours expire.
And with it being digital, I imagine you could have it send you an email when it gets within X number of hours of warranty.

I wish ... I monitor these things on a timely basis, esp when the hours are getting up there, just that when it gets real close and have the time is when I'll do the pulls.

That's what nice on the NEC units is the warning time- like 50hrs -(and flashing tail lights) before warranty expires on the bulb.

But as with all xenon bulbs, their effective light output is within the first 50% of the bulb. Then, the light color begins to looks "blah" until the pulls. And with digital, having a bulb that goes "blah" really looks bad since the natural light reflection off of the DMD's isn't a true color match, ... and esp. with 3D .

Sure, I bet you can run 4K bulbs 300 + % past warranty hours (I've seen CXL 40 bulbs with over 4k hours on them and the envelope still looks great - contacts inside are definitely worn though ..) and they'll never explode and flicker, but just hate to see how the light output looks like..

Film can get away with it with flickering and other stuff that goes on with a tired bulb, but it can really offsets a digital presentation and a flickering bulb in a digital unit is something you DON't want to see the results on the screen.. why of the necessary pulls at warranty.

It can be a bit insane at times... - Monte

I have an image of an exploded lamp in a Sony at work. It's not a pretty site. That reflector looks like it vaporized.

Monte, putting the "make believe" Sony thing aside, your findings are exactly opposite mine. I can take a bulb from a film lamphouse that is flickering looks awful and put it in a digital and it looks great. (No doubt there is still flickering going on, but the integrator rod covers it up. The instant I see a flicker in digital, no matter what the hours are it is coming out.)

I have a feeling whoever spec'd your projectors failed to do the job properly to account for bulb degradation.

..same thing in a BARCO module when a bulb goes - nothing exists.

I attribute our dark bulbs due to poor exhaust - not enough CFM's ... yet, the airflow from the seal blowers seems sufficient, but something still isn't right.

..but, what do I know since I've had no formal digital training, thus some of the stuff that I've been posting here, once again, has been told to me.

Looks like I really need to be a part of many digital installs to really get the skinney on all of this to be more accurate in saying things...

Monte,
The major manufacturers all offer some type of training for maintenance on the machines.
Sony's I think is the cheapest, ironically.

I could b**** for a while about where they let us down after installation, but one of the most mature things Sony has done, in my opinion, is fixed those issues and admitted where they messed up.
Namely support.
The infrastructure now is phenomenally better than it was 2 years ago. The NOC is MUCH more helpful and knowledgeable than the old Sony support folk.

But I digress. They can teach you most of what you need to know in a 2 day maintenance course, assuming you know very little. The rest is really just experience with the machine.

Having to tear them down once or twice a year for cleaning/parts replacing (our booth air is FILTHY!) has taught me quite a bit that most all manufacturers (not just Sony) arrogantly overlook (except when trying to sell you their service plan).

Oh, do agree with the experience thing - it's all on your own.

thx - Monte

NEC/Strong probably are the "cheapest" in the training department...I've heard nothing but "expensive" when it comes to Sony training.

Barco is probably the most comprehensive of the lot. Including what must be done to keep it well maintained. In fact, their software will tell you just what needs to be cleaned and when.

Well. I've learned my lesson about respecting the lamp alerts!

The alert came up last week and the soonest I could get to it was Saturday morning. I was going to anyhow because the light level was dropping; at full power we were getting 14fL in 2D and 4.5 in 3D. And I like to keep it around 16fL in 2D.

Well, as I opened up the cover on the lamphouse I heard a crunchy sound...

 -

Less than 100 hours over and it exploded in the middle of the night after the projector was set to standby.

Yowza.

I'll also add, this is the first time I've ever had a lamp explode in a lamphouse in the 10 years I've been doing this.
I'm still baffled that this lamp was so close to the warranty period still.

Eh. Knock on wood, but they haven't charged us for most of the parts we've had to replace on these bad-boys.
Optical blocks and PS converters come to mind. Though it's really the design that limits the optical block life to ~2 years.

Interestingly they're sending out Sony lamphouses in place of the stock Ushio lamphouses they shipped the R220's with. Same design but with a Sony tweak.
Most notably the front support which SUCKS now.

However the light output on this machine is drastically improved with the Sony module vs the Ushio. So that's nice.

They give you free parts on a lamphouse with an exploded lamp that was over-hours?

Wow!

I think he means "so far, they haven't made us pay" rather than "we aren't going to pay on this particular incident." I could be wrong, though.

"woo...!" ...tons of money for the reflector alone.... "ouch"

Interesting that it would go while on standby .. unless the bulb accidently got left on and the exhaust was turned off.

That's the biggie with large wattage bulbs: you get them out right after warranty since the quartz can get so weak due to the high heat.

Bummer on this one.
