The white ceiling and tan walls will indeed affect measurments.

Tilting the probe and also checking various areas of the screen will deliver differing results partly due to a small amount of color uniformity issues that very nearly every projector has and even the tan walls in your theater.

In other words, if you set up your meter on your screen and I set up my gear right next to it, in a perfect world we would get the same results. As you know, it is not perfect.

The GOOD news is that our eyeballs might well not see ANY difference that is reported by our gear. The gear is way better than our eyes.

jkasanic,

U can fix this gamma droop using Sony's Image Director software. U will also realize that if u select rec709 color space u will have undersaturated colors. U will need to use the wide color space and the in built cms to fix the colors. There is a thread in hifi.de forum talking about this gamma droop.

It seems to be an ongoing process and after a while you won't be able to even recalibrate the colors to the Rec709 colorspace, and even with gamma setting 2.6 in the menu you can't reach at least 2.2.
Some projectors also seem to lose native on/off-contrast.

Almost every HW50 that has been measured seems to have these problems. We were wondering if this is not an issue in the US or elsewhere?
I think that here at AVS there are also many users that do have calibration equipment and measure their projector from time to time?
Did you never encounter some problems?

Also Ekki Schmidt from cine4home has investigated the problem. His first guess was that the color filters degrade but the funny thing is that the native color space (well actually there isn't realy a native colorspace at the HW50 Ekki said) seem to remain and not drift towards blue. So his last guess was that it may have s.th. to do with the blue gamma and may be corrected with software.
The big problem is that the Sony Support did nothing at almost all cases and returned the projector with the statement that this would be normal wear...! (after a few hundred hours!!)
Ekki Schmidt also thinks that it has not so much to do with the amount of hours that the pj was running but with the total age of the projector.
Also it seems to have nothing to do with the lamp because Ekki tested this also with a new lamp and other users did the same with no result.

There is a big thread in german hifi-forum about that issue: http://www.hifi-forum.de/index.php?a...4&thread=13697

I can not translate everything for you, but look at the measurements that were posted.
I measured a HW50 of a friend of mine twice and could document that the problem is ongoing, look at these measurements: (I'm not sure if you can enlarge the pictures when you're not a member of hifi-forum): http://www.hifi-forum.de/index.php?a...postID=931#931
If this drift towards blue will be ongoing we won't be able to recalibrate the pj!!

I am experiencing a quite good amount of flicker in low lamp, like in this videos:

In high mode it's fine.

I run all the time on low and while it happened sometimes before, switching to high for a few mints solved it, but now seems permanently.

I tryed running high for around 15h, but like i said it still flickers again as soon as switching to low.

Lamp has around 700h, is the lamp? Or something wrong with the unit? If it were because of bad ballast/power supply, would it do it in high mode too?

My recommendation is to run it in in high for a good number of hours (try 30-50 hours). I had/have the same issue. Switching it to high would solve it for that run, but after a few hours of running low, it would flicker again (HW50ES). After running it for a good number of hours in high, I've now used it ~15 hours in low, and it's so far, fine. It's likely a lamp issue.

I can't really see how it's flickering in your video. Is your flickering a very constant, rhythmic flickering? From the bottom video it looks.... sporadic/not constant. Mine is/was a very constant/consistent flicker in low lamp. If yours is something different, it might be a different issue...

Rather hard to see on my computer screen, and the camera only picks up 1\3 of the flickers, I do recognise it from my own HW50.

Mine has had this flicker in low mode almost since I got it with 200 hours on the bulb, started noticing it after 220-230 or so.
(bought it slightly used) setting to high does also nothing, it starts flickering again immediately when I set back to low, in short I have been using high mode since I noticed it.

Running in high for a bit sorts it for most, but it certainly not unheard off that it doesn't. As it seem we both are subjected too here.

As far as I can tell, Sony intended for the hw50 to be run in high, and the 2000'ish hour lifespan of the bulb is for usage in high mode, and the factory color settings intend for high brightness.

I planned to replace around 1400 hours regardless and have budgeted for just that.
I expected to reach that already by end of fall last year, but as it turns out I'm still just shy of 700 hours on this first bulb and with a mere 90" screen, I'm not lacking for brightness.

It's one semi serious flaw with these models, but I doubt they will sort it unless the completely swap lamp type.

I tend to agree. I can't run in low lamp either at this point - about 800 hours in. I have to leave it in high since running in low (even after letting it run high for 100 hours) also brings about the flicker.

Just cleaned the filter for the 7th time... 3500 + on the clock. Reset at three k to eliminate "replace lamp" message.


Flicker happens, as I have said before. Just run it for a day or two wot. Repeat as necessary.


Still reading plenty of lumins off of a short throw 1.0 gain screen. 14+fl to eye after the math +/-


My spectrometer is old...
Nothing is perfect.
My Cadillac isn't 100%


The films look great.

Running it for a day or two on high does NOT fix the issue for many of us. It did initially, but not anymore. Within an hour of watching, it will flicker on low. So I just run high now, which is a bummer since I don't need the lumens.

That IS a bummer. When you swap lamps, if it still happens, I'd give the Sony tech guys a try.

My situation may well be different than most. If I am going to possibly watch a bit of golf or something in the am, then know that the bride and I will be watching a film in the eve, I will leave the pj on. I know, I know...horrible waste of power listening to music with pj showing pandora or sirius whatever but it worked on the showroom floor for years and I just can not get myself to cycle the power too often. That may well be why my setup flickers less.

Who knows?

I did not mean to infer your case was less than important.

I must have been one of the unlucky ones since my lamp popped at below 2000 hours and all this time I run it on low lamp mode.

I am sure that in the service menu Sony has a "power cycle counter" or some such. The number of times the unit is switched on/off may be of greater importance with regards to lamp failure than actual running time.

Oh I never thought that. I do have a new, spare lamp that I can test, but I'd rather just wear this one out first before messing around inside the pj!

Is there any HW50ES owner that had noisy 3D mode and it was repaired successfully by the sony prime support repair center?

So reading about some people with issues on the HW55ES and flickering lamps, and myself experiencing the flickering lamp on my HW50ES (and the HW30ES), is it generally agreed that the LMP-202 lamp that comes with all HW30/50/55 projectors is the culprit?

Just seems surprising that Sony haven't addressed the issue...

That's easy, Sony designed it and these projectors to be ran in high I'm honestly suprised it has a low mode setting to begin with.

All statements to lamp life etc has been made as far as I can tell with the lamp in high power state.
Colour calibration is also a bit off in low mode, unless you get a professional to calibrate it.

I have just tried to contact Sony Re my VPL-HW50ES re flickering I notice when playing sports like Rugby where the green is flickering terribly.

They claim no knowledge of it, and it unbelievably has only a 12 month warranty on it.

Is it just a case of a new lamp or is there a more serious issue at play?

Is there an easy way to determine how many hours I have used this bulb for ?

As previously mentioned, simply run it on high lamp for a spell. You may have to do this every so often.

Check the lamp run time on the main menu.... bottom icon. Lamp hours are recorded there.

I've 4000 hours + on mine. At 3k it will say "spend money and replace the bulb". Simply reset the lamp timer.

Clean the filter like your life depends on it. Every 500 hours..

Read the manual too. Lots of good questions answered there with a little research.

Thanks. I checked and it's sitting at 1674 Hours and the Lamp Control is set to High and always has been. I run on setting cinema1. Attached are my settings for this.

Since you report some flicker on high, it may well be the lamp does have an arcing problem. Just for drill, check to see if it worsens when set to low.

If it does, replace it with the backup lamp provided by Sony . A LMP202-h I I believe. If there is no flicker with the new bulb, run it and use the other for a backup.

While settings will vary greatly from room to room, there are no issues with yours.

Thanks. Bulb has done 1700 hours, if it's rated at 2000 hours should it be covered under warranty if it's "arcing".

Pretty sure it's not an issue with the actual projector based on what other people have said in their posts here. Is $899 NZD what you'd expect for a replacement? Seems very steep! (1/4 of what I paid 18 months ago).

I've not cleaned the filter recently, could that be part of the problem?

$900 for a bulb? I do not know what the nzd is compared to the usd but NO WAY should it be 900.... Anything! Shop more and better.

Cleaning the filter is MANDATORY!

Every 500 hours like a clock and you will not have any overheating problems. Could it be a possible issue with your flicker? Not likely but yeah... It could be. Very very easy to fo so just fo it.

$300 for a lamp in a housing. The only way to go unless you have some experience with actual bulb only replacements.

Lessons learned!

Not sure where to post this, unless someone has a better suggestions, such as our admin.

It's not exactly a scam since I got my money back by using PayPal on a recent transaction where the seller (alias John Pessoa with few postings and never on this thread) got my money. However he never sent out the goods a 13-day duration. Credit card companies could do a much better turn around.

In case someone did not notice the original ad, the price was below market. The ad said VW50, but the picture was actually a HW50. I almost backed out the deal but decided to go with it. Hindsight told me my initial instinct was correct.

Luckily I've my main projector, otherwise I would be "movie-less". Time to look for another backup.
