I'm sure we can find all sorts of examples.


Has anyone really got 10000 decent hours out of a CRT? No way. And I've fixed enough of them (10+) to know they are not that reliable, but they are repairable.


I love my CRTs, but I think the end is nigh. Not sure. It's not longer a no-brainer like it was a couple of years ago.


I was seriously impressed by the Sony HW15, and seriously unimpressed by my green tube.

I'm with Mark on this one.
Crt tube life/cost vs Bulb is a non issue anymore.Bulbs can be had for about 300 and replaced every one or two years,so non issue really.Replacing CRT tubes is costly and time consuming.
Get a Digital with a good warranty and you're right until the next upgrade.
Don't get me wrong,I love my 1209s and can't bear to part with it,I have 2 sets of spare lugs to burn through so I'll have this darn thing for a while yet

Copied from another forum on bulbs:




Please post experience of JVC HD750/350/550/950 bulb lifetime / lamp brightness drop



I can't speak for the JVC line, but a couple of years ago I tracked about a dozen lamps in various projectors. The average was about a 50% decrease in brightness right around 500 hours. After they reached the 50% point I stopped tracking them, as I personally consider that the point where they need to be replaced. The longest lasting lamps back then were from Sim2 and the shortest ones were from Optoma. YMMV....



This is the main reason that I'm going to wait for an led (or laser)-illuminated product before I upgrade again. I would be happy with even 500 lumens if it remained that over its (long!) lifetime.




I have just over 600 hours on my bulb and had my HD750 calibrated this weekend. We had to turn up the bulb in order to get a proper calibration since the bulb had dimmed considerably. At this rate, I will probably have to replace the bulb at 1000 hours...not the 1900 it is said to be rated for. Not to mention will have to have a tweaking done on the calibration as well. Please let me know if anyone has a reliable source for bulb purchasing.
Thanks.




This is one reason why it's hard spending $4k-$5k for a projector when the bulb dims so much. I didn't have any issues spending this on a top end plasma but it's disappointing that FP quality changes because the bulb dims at such a fast rate. Thankfully my average seems to be about 250 hrs/yr on my bulb (FPJ1) since I only use it for movies.



I have never used a projector yet that I didn't have to change out the bulb well before it's stated life ( or anywhere even close ). Loss of brightness, or using " too big a screen " ( or both ) is IMO front projections " dirty little secret ". I don't think I've gone beyond 500 hours on any projector before putting a new bulb in except for my dVision 1080p ( which uses 1 or 2 bulbs at the same time - I still changed out the first bulb at 875 hours with both running ).

Well, it depends on the Sub Cont pot.

I did the white balance myself on that chassis, and the pot was probably a little low.


The new chassis is at 60% for roughly the same output. Which is just before the image gets a bit blurry.

I've said it before, I'll say it again, the big difference is the life of the chassis. ANYTHING new electronics today, be it computers, flat screens, MP3 players, etc are designed to last 3-5 years. CRTs can still be running strong at 20+ years old with minimal repairs.. and repairs can be done to CRT.

I agree, the tube/bulb issue is not really an issue any more due to bulb pricing, but if you've spent $300 on a new bulb and the chassis dies on a digital, you're out $300. If a CRT chassis fails after you retube it, you can get the failed board repaired, or heck, even take the tubes and put it into another chassis. You can't do that with a digital.

You can get a humdinger of a digital projector now for 2k....it could easily last 5 years where the replacement will be 2k and likely have unreal picture quality.

Crt is dead and worthless...anyone trying to sell one would agree..so, why the discussion?

The bull case for crt is effectively dead in every conceivable way...and from every conceivable angle.

I was at a digital friends house the other day...his bulb is over 3000 hours and still looks good. In fact, it may even look better than when it was new...lower output mimicks crt. Every digital I owned, I used with an ND filter to take the brightness edge off.

When this XGLC has had it's day, I won't even consider another crt...I think

These digital vs CRT threads are just comical. The battle just keeps going back and forth. But whats interesting is that when REAL component level techs post they are just saying dont be brainwashed into thinking these digitals will last as long as CRT even "IF" PQ of the digital is closing in on CRT. And dont be fooled by some that say that you can't get 10s of thousands of hours on a well set up CRT.

There will always be those who are better fit with a digital, without a doubt. Hell, even 5, 10 15 years ago when digitals were real crap they were still sold by the thousands. Some people just dont have the know how or ability to have a CRT projector.

For some the cost is not relevant so bulb replacements and burned up projectors at low hours doesn't matter. And for them digital would probably be best also. There are many reasons to have digital.

But for those with limited initial budget and not much budget for a replacement projector or bulbs and have the ability to learn how to setup a crt even at a basic level, these are still the true CRTers. And you cant change that because they cant afford it. And by telling them they are (something)for wanting to stay with CRT will just piss them off.

There are many very happy CRTers, so leave them alone.

SO basically, if you want to switch to digital, go ahead but STOP telling everyone else that its the only way to go. Because your wrong. The way to go is what one person chooses to do based on their own reasons.

And lastly from a techs point of view, digitals don't last long, period.
