In my case I set the output to auto. Should I be setting it to match the 675? I assumed the output varies by disc and that the Oppo outputs the max for that disc. Is that not the case? If so, if I set the Oppo to a higher output than the disc does it upconvert?

I should really know this stuff by now!

If you want to be sure that you get no banding or image issues on these Sonys, then set the Oppo to UHD24.
This ensures that:
24hz plays as 24hz
25hz plays as 25hz
30hz plays as 30hz.
That setting will also play 50hz as 25hz and 60hz as 30hz. Thereby allowing Billy Ray Cyrus's Long Lonely Walk to play banding free @ 30hz. Smooth, but not quite as smooth as the native 60hz.

So I measured my 675es lamp when I first got it and now.
New:
High - 1680 lumens
Low - 1000 lumens

Now after 890 hours on bulb:
High - 1014 lumens
Low - 557 lumens

The bulb has been run about 300 hours on high and the rest of the 890 hours on low. Doesn't this seem too severe of a loss in lumens for only 890 hours on a "6000 hour" bulb?

Whilst I cannot help you with any comparisons, that does seem like a fairly large drop in lumens. However, if it still looks good onscreen, then don't sweat it I would say.

A lot of peeps on here do seem to advocate changing bulbs at the 1000 hours mark, so you aren't far from that.

FYI I think the 6000 hours figure is bulb life on low until expired, not a bit dimmer.

On the bright side, (pun intended) a new bulb will doubtless get it back up to where it was again.

To put this in perspective, my JVC x750r bulb was at 2200 hours and still super nice looking in *low lamp* mode. I'm not really ok with $500 bulbs that only last 1000 hours. It might be enough for me to dump the sony projector and go back to JVC if that's just how it is.

My expectations on the bulb was 6000 hours means maybe 4000 hours if run in low lamp, maybe 2000 hours if run in high of usable bright bulb power. Since I only run 4k projector for games, maybe I'll go back to JVC and rig up a dual projector setup.

It does seem like the bulb may have an issue, I had over 2000 hours on my VW90 and it still looked great (always on low however).

Are there any suggestionsfor getting lamps? Which e-tailers are the best?

Honestly though, buying a new lamp every year is a worthwhile expense for what you get, IMHO

FYI: I bought my projector new lamp 1/27. I have no problem buying a lamp a year. This has me at about 2 lamps per year or maybe close to $100 a month to use the projector. It's a bit silly. When the bulbs went up from the ~$250 range to the ~$500 range, they also went up from 2000 hours to 6000 hours so it was ok. But to only get 1/4 or 1/5 of the advertised life is not ok in my opinion. I expect about half advertised life, which is how it's always been. Perhaps my situation is a fluke and I just got a bad bulb. I'm now running bulb on high, which looks like it use to on low. It's ok for most stuff probably not good for HDR or 3D now. Luckily I don't care about that. But if the bulb drained this much running on low, now it's on high it'll drain faster. My guess is if I went 900 hours on low, I only got another 300 or so hours left and this thing is unusable. Not only that, but the bulb flickered on low for the first 400 hours and only recently stabilized, now its going dead.

I will say that I ran the auto calibration last night and while it didn't brighten the picture, it did make a lot of changes to the color balance and things look better. With the new bulb it didnt have any changes it wanted to make and now it does. So at least the auto calibration feature is really neat. I wonder if when I swap bulbs if I need to run it again or if the bulb reset procedure will return that to defaults.

You may have just been unlucky and gotten a bad bulb. You also have to remember that bulbs don't degrade linearly. They drop the most within the first 1000 hours and then seem to drop at a much much slower rate until they finally fade. All bulbs also don't degrade the same. It is a little bit of a crap shoot with bulb projection.

Having said this, bulb projection and the problems associated with it, are only one reason why I would love to go laser in the future.

One of the reasons I went to 4K is so I could have a good work monitor. I use it to work and listen to music a few hours a day.

It is for this reason that I have a pop up tv planned for in front of my projection screen. Only use the lamp for proper movie watching

There's just no point owning a projector if you're going to have a small tv in front of / in back of the screen. That's just super silly. As I said, my old JVC was at 2200 on the bulb and it was still looking fantastic on low. At some point I'd be moving it to high power and getting several more hours on it.

Steady on. Super silly is your opinion but everyone’s rooms and setups are different and trying to imagine what someone else does but translate it into your environment I suspect isn’t a great way of thinking. My room is not a dedicated cinema room. It is a lounge room which sometimes gets used for movies. Hence my choice for a television as well as a projector. It sounds from your description like you have a dedicated cinema room but are also using your projector for computer and office work as well as for displaying the music details. I may have read your description wrong but I wouldn’t dream of using my projector for long hours each day on computer work.

You can reduce the cost considerably by just buying the correct lamp and reusing the original housing too!

Why is that? We use our projector as our primary source of all entertainment. It is used for our satellite TV general viewing, video gaming, and movie watching. We have put over 1600 hours on our projector in 7 months.

We love it. Nothing wrong with using something that you paid good money for.

Have you personally tried this? I have considered doing this but was a little concerned because I had read that some of the third party bulbs did not perform well and often would explode when they aged. Possibly causing some damage to the projector. I am sure it isn't that bad but was concerned that in the end it might not be worth it if the bulbs didn't perform as well.

Yes I have.

All you have to do is look at the actual bulb fitted inside the housing and buy the same bare unit.
All the bulbs in my Sony projectors have been Philips bulbs.

So I bought the same bulbs when required and carefully swapped them into the original housings. Easy enough to do if you are adept at such things.

Be sure to avoid touching the reflector and element as they can fail as per car headlamps if oil from your fingers gets onto them.

Ok, thanks I will try this.

I have replaced many projector bulbs in the past, even when they didn't come in housings and were near impossible to get to in rear projection TVs. I always wear those disposable latex gloves like a surgeon wears to work on anything electronic these days. Finger oil is a problem for anything glass that heats up.

Oh nice. Do you have a part number from a prior 675 swap? Or a place to refer to?

Sorry no I don't, as I never got round to changing that one. When I took it out to inspect it shortly after getting the unit and finding it quite badly flickered, I am sure it also said Philips on it, but I can't be sure however.

I'm pretty sure that only Philips bulbs are what you want as that's all Sony uses on these. There are 3 bulb manufacturers and of the 3, Philips has some patent that seems to be related to something sony uses. Sorry for being so vague, but I was reading about it and forgot the details. If you buy real raw Philips bulbs you're probably OK here. I bought one to swap in mine in the next month or two.

I ended up hooking back up my JVC RS500. It has 2270 hours on the bulb and I just took some lumen measurements and its still at 1750 lumens high, 1250 lumens low (it's rated 1800 lumens) so the JVC bulb, after 2270 hours, is basically running like new still. This is the behavior I expected out of my Sony. Honestly, the JVC looks a little better for TV/Movie content anyway. I think I'm going to use my JVC for video and my Sony only for games where you can really benefit from the 4K and the deep blacks aren't as important.

Built a special addon to my mount so both projectors are always hooked up and whichever I power on is the one that works.

I think something wrong with your measurements. I measured my JVC RS600 and it had just 1350 lm (1900 lm in specs) in high lamp natural mode. New calibrated JVC X7900 (RS540) was measured to 1310 lm in highest mode. The brightest lamp based JVC that i had was RS400 (1700 lm in specs) with 1600+ lm in high lamp mode and it was much brighter than my RS600 at the same screen (I had both at the same time). So don't trust manufacter specs.

I don't know what happened with bulb on your Sony, but the brightness on new sony must be on par with RS400, not the RS500/RS600.

P.S. Where i can find your comparison between Sony 675 and JVC RS500? I plan to change my RS600 to 675 or 385 and want to know what expect.

Sorry for English

It's very possible my measurements were wrong. But I use this meter mainly for relative measurements to track the measurement change over hours on the bulb. My method of measurement is:
1) Turn off auto iris and set to max
2) Set to bright tv / natural
3) Display full screen white image
4) Put probe facing projector on center of the screen and take down lux measurement.
5) Convert lux to lumen using screen size math.

The sony bulb when new was just as bright (in high) as the JVC is now. The sony bulb when new was 200 lumens dimmer in low. The JVC runs its low power hotter than the sony. I never took measurements on the JVC when new.

I have the following measurements. You can assume my lumens are not perfectly accurate but they are relative to each other at least:

1) Sony 675ES 200 hours on bulb high lamp: 1652 lumens
2) Sony 675ES 890 hours on bulb high lamp: 950 lumens
3) JVC RS500 2280 hours on bulb high lamp: 1750 lumens
4) JVC x500r 100 hours on bulb high lamp: 870 lumens

When the sony bulb was new, it was really close in brightness to my JVC at 2280 hours. It took a visible crap about a week ago and that's when I got my measuring tools out and found how much it dropped.

Yea, so I've really done a hard comparison on these two projectors the last few days. Here is my personal conclusions:

Sony:
Sharper image all around all the time even at 1080p
A little better detail in shadows
Reality creation is awesome and nothing in JVC works as well
Dynamic iris is almost seamless and you never notice it pumping.
Gaming detail is tons improved over jvc in eshift. The difference in games is really huge.
Details in like those youtube 8k drone videos is tons better on the sony due to its sharpness.
Sony bulb sucked, it flickered on low for 400 hours then settled and then at 800 or so hours took a major lumen drop.

JVC:
Contrast is noticeably better.
JVC looks slightly brighter while maintaining better black.
The black on the JVC is jet black. Star fields are incredible. The blacks are so deep and the stars are bright.
JVC seems to do tons better on bulb life - at least from my experience.

For watching TV and movies, even 4K movies, the sharpness difference is very minimal and I'd say that the JVC all around looks better in almost all cases. For playing games or working on PC desktop, the sony is really a lot better. It's very crisp and sharp. And in games you get a massive boost in detail. It's a real noticeable step up in this regard.

So I think maybe my Sony 675ES is busted and the bulb may not be the problem. I think the problem might be in the iris, and if the iris is not able to fully open, maybe this is why I lost so much brightness.

If I disable automatic iris and move the iris brightness from min to max, it is not consistent. Often around 50 it clicks and all the sudden gets brighter, but other times it does not. Between 95-100, it seems to click and get dimmer like if around 95% brightness I move towards 100% slowly, it often flickers and dims. Moving the iris back and forth does not result in the same brightness stopping at the same point each time.

So much difference in contrast? I thought the 675 should be only slightly worse than the RS500. I attached 2 photo with comparison of black level. First with comparison between Sony 665 and 785 and second with Sony 385 vs JVC RS540. To which level of black 675 is closer?

What's the distance from your eyes to 135 "screen? Sony recomend to sit as close as 1.5x height of the screen to get full benefit of 4K.

There is only one way to check - buy a new lamp. I do not know how much repair will cost, if it's Iris. But you have to completely disassemble the lens to get to iris and replace / repair it.

Any 675 should still be under warranty, so I would go about getting it repaired. What you have described sounds like an intermittent iris.

My 550 looked more like the right hand image in the first picture.
