BenQ W 5000 little Test - Page 165

post #4921 of 5147
No, this is normal misbehavior for W5000's iris, at "0" position. Should be much less visible at "1" and practically negligible -when watching material other than patterns- from "2" and upwards.
post #4922 of 5147
Hi, i wish to ask if someone did unlock w5000 zoom to obtain a more short throw distance. Another question, can you see (with dynamic black on) the iris pump up and down with the light of the image?
Thanks, bye.

Do you mean unlocking the iris? This doesn't effect throw distance. There is no unlocking of the focus rings.

The DI movement is not noticeable for me. Results vary.
post #4924 of 5147
No, i mean something to do (for ex. to move or modify the objective or the zoom ring forward or backward...) that allows to fill a 80" from 3 mt. distance.
Thank's and excuse me for the english...
post #4925 of 5147
I guess you're referring to W9000's zoom hack; I'm not sure this is possible with W5000 too.

DI movements can be occasionally visible, not so much as brightness-pumping on the entire image, but more on white subtitles in really dark scenes. Selecting gray as subtitle-color not only makes pumping less visible, but also makes subtitles more comfortable to the eye.

I did gamut and luminance in native lamp mode using 100% saturation aimed at the screen, then did temperature at a lower saturation setting. When doing temperature I made some slight changes (one maybe two) to cyan and magenta y and a couple to magenta x. I bumped the contrast up one step also. I did not change desired white from my previous results using 75% saturation windows. Some results using the AVS MP4 measuring 75% color.

I hate to be the guy that beats a dead horse, but has there been any definitive conclusion on where to buy a 200/170 replacement lamp for the W5000?

All I can find are 200/150's. I don't mind, in fact I would prefer, buying just the lamp and no housing.

If there aren't any 200/170's available, are those who bought the 200/150 satisfied with the brightness and is it comparable to the original?

Also, any advice on where to buy? I see a bunch of 200/150's on ebay and quite a difference in price for just a bare lamp.

Thanks for any help fellas, appreciate it,
George

Hmm, I just replaced my bulb not too long ago, so I should check which type it is as well. At any rate, I've just discovered that there is a dim area in the lower left corner of my projector and I'm a little concerned about it. It also seems like the image overall is slightly dimmer than before. That could just be in my head, though, but...

Anyone else encounter this? Hopefully it's just me that's dim and I overlooked something small. I have cleaned the lens with a blower, so that is not part of the problem...

Hey, I appreciate your response. It should state right on the bulb either 200/170 (what original bulbs state) or 200/150 (what seems to be the only replacement bulb available). Not sure if there really are any differences between the two.

About your dim area in the lower left corner, do you see similar in the upper right? If you have your manual iris closed down to 4 or 3 maybe, this is normal. I too have a dim lower left and upper right with my manual iris at 4 I think. If you move your manual iris open, you will not see dim corners anymore. I don't think it negatively affects the actual 'in real use' image though either way, other than of course better black levels and contrast with closed manual iris as intended.

I'm still hoping others will comment on their replacement bulbs. Mine now has about 1600 hours (and I bought a refurb with about 400 hours on the bulb) so am seriously wanting to replace the bulb pretty soon.

Thanks all and have a good week,
George

What should I use to clean the lense? Will a cleaning liquid damage the lense or just use a microfiber cloth for eye glasses. Smoker in the house.

Ok, even though you are a smoker, I wouldn't recommend you use cigarette smoke to clean your lens...

Seriously though, unless you have something sticking to the lens, I wouldn't recommend you use cleaner on it. Try to use a lens brush to brush off anything from the lens. If you do feel like you can't get the lens clean unless you use some sort of liquid cleaner, my recommendation would be as high a quality cleaner as you can find. Camera stores usually will have something high quality. Try to stay away from department store 'lens cleaning kits' as they are usually very low quality.

Try brushing with a lens brush first. Most 'crud' on the lens doesn't even affect the image very much, if at all.

Good luck.
post #4935 of 5147
I got a product called Purosol from a local camera store. I sprayed a bit of it onto a few pieces of lens paper (lintless) and took a few swipes (not rubbing back and forth) across my anamorphic lens to clean it. Don't try to do this when your pj is on. Rather, get a strong light (like a reading light or something) directed at an angle to your lens and clean it that way. If you must. And I say this because even though this stuff cleaned my lens pretty well, it wasn't as good as before (apart from the fingerprint...doh!). Best to leave well enough alone if possible.
post #4936 of 5147
Bub,

the dimming I mentioned was only in the lower left portion of my screen. You mentioned it could be an iris thing, so I went into the menu and checked things out. turns out, I had the iris set to +9, but when I turned it down to zero, nothing changed. Then, as I began to turn it up again, the image began to brighten (waaay better than before) and the dim section in the bottom corner went away. Maybe the iris was stuck or something. At any rate, I hope this helps others that may have a similar problem.

I know you wanted to get the lamp only, but I did check the replacement lamp I got. Or, at least, the part number from the website where I purchased it: 5J.05Q01.001
I'm not sure if it's the 170 (couldn't seem to find much information on it and I'm not too into having to pull it out of my pj to check)...Maybe you'd have better luck finding the specs on this.

Damn, it was hella expensive but the image is fantastic and good as new. I don't plan on getting a new projector anytime soon, either. This pj throws a nice image.
post #4937 of 5147
I'm starting to wonder if the original lamp was 250/170 instead of 200/170. I know all the replacements I can find have a stamp on the bulb itself, 200/150, so I assumed the original was 200/170.

I've never used my bulb on high before so that wouldn't bother me, but what does bother me is the disparity between 250/170 and 200/150. That seems like a completely different bulb.

Too bad we can't figure this out for sure...

The original lamp high mode is definitely (only) 200 watts. It would be a light cannon with 250 watt lamp.

However there is the lower mode 170 or 150 watts is not clear yet. I trust BenQ at the moment saying it is 170 watts (printed on the bottom of the projector).

I finally rechecked my W5000 calibrations. It is almost a year from my last calibration and bulb hours have gone from 450 to 1082 hours during that time.

To my big suprise it seems that my unit HAS NOT drifted virtually at all during that time. Even brightness did not drop more than less 1 FtL during over 600 hours. I'm still getting abour 8.6FtL DB off (DB on gives additional 0,5FtL (about)). Colors and gray scale are pretty much as they were.

Here are my good old settings I've been enjoying a lot. I did not bother change them at all since image looks just perfect and HCFR numbers are about as they were year ago.

Well, I'm not sure we have to go that far, trusting BenQ, on this matter. There are pictures available that do indeed show a 200/170 Philips lamp. The issue is two-fold, are these 200/170 lamps used in the W5000 and if so, where can we get one?

Why does the replacement bulb part number match up with 200/150 lamps?

I've been a BenQ customer for maybe 2 years now, give or take and I've spent many an hour on the phone with multiple BenQ representatives, up to and including lead management, and I feel completely safe in stating that I never once felt like the representatives I was speaking to had any definitive answers to any question I had. I wouldn't trust a phone call asking BenQ to comment on whether or not the W5000 actually used a 200/170 lamp, the literature not withstanding, and/or if purchasing a replacement bulb directly from BenQ would result in a guaranteed 200/170 bulb being sent. (This is not necessarily me singling out BenQ, but rather a general comment on many years of experience in dealing with representatives, not very many of which had very clear knowledge about the products they were supposedly supporting.)

What I would trust is a user here on this forum posting that they took a look at the writing on their original bulb from their purchased new W5000 and it stated 200/170. I would also trust a user here stating that they purchased a replacement bulb from BenQ and it was marked as 200/170.

I have about 1500 hours on my W5000 purchased refurbished from BenQ, so I have no way of knowing what the original bulb's specs were or how many actual hours were on my unit. I would very much like to buy a bare replacement bulb, I have no problem swapping out the bulb and reusing the housing, but I really would like a true OEM bulb, meaning 200/170 not 200/150 if possible.

If anybody can address that issue with personal knowledge, I can only assume that I would not be the only one grateful.

Well, like I said "at the moment" means I trust them because I have yet to seen any evidence that the 200/150W is the same as the original bulb. What I've seen here supports the fact that original is more likely 200/170.

Good guestion.

Perhaps Philips UHP type TOP 272 and 302 are the same physical size...
http://www.projectorlampsource.com/uhp_lamps.html
Based on this list both 200/150W and 200/170W bulbs do exists with similar specs.

My second lamp is on the way from the BenQ store. I will see if I can check what is said on the lamp this time. I measured on a wall recently and I still had correct green and red primaries. After lowering my red a couple I had correct temperature again also but I found 2.4 gamma best.

Steve, is that a warranty replacement bulb or are you paying for them? I'm going to assume it's the entire bulb and housing correct? Does the bulb have a stamp stating 200/170?

I see ~$360 on BenQ website, that about right? I really don't want to spend that much for sure. I see it listed at part number 5J.05Q01.001.

I wish I could find just the bare bulb, the 200/170 NOT the 200/150...

Yes this is the second for this price. I did not see the part number when I installed it last time and I'm not going to take the lamp out just to check since the first install failed and gave me lamp warning, then two blinking red lights and started to get real hot but I unplugged it before blinking red lights the third time... I will check closer for the part number but last install I was more concerned it just working so I hadn't checked. The new one should be here in a few days so I'll check again then.
post #4945 of 5147
I bought a bulb from projecetorlampsworlds.com and it has the same part number as the one from Benq. There is nothing on the bulb about watttages on either bulb that I can see.

The replacement bulb did seem dimmer than the original. Kinda like having the projector on low instead of normal compared to the original. Still, the picture looks great.

I will purchase from them again since I don't believe there is a 200/170 bulb available anywhere.
post #4946 of 5147
Just wondering - is there a service manual for the W5000? I want to take mine apart (warranty is over) and clean the lens assembly inside - there is a nasty double reflection that I can see in certain scenes and it definitely looks like an internal reflection!
post #4947 of 5147
coming late into the bulb discussion, just thought i'd offered up a view

i just received a new bulb and housing for a warranty replacement (via mack warranty)
they used a third party company to ship it. the inner box it came in looked official benq with all the same markings as one i bought myself.

the bulb inside says 200/170


i have a second bulb/housing i purchased privately from one of the popular internet places, but its in the PJ so i can't look at it. i will agree that it might be a tad dimmer, but that could just be my head. it too came in the same identical packaging with same stickers/labels as the warranty replacement bulb.

i don't have the original bulb to look at; had to be sent back
i will add the original bulb never quit on me. i ran it for nearly 7000 hours before i finally sent it back as a warranty claim with a screen shot of the hours. it got dim for sure, but not an issue in my cave. that same bulb also survived 5 shippings, 1 bought, 2 back and forth repairs
post #4948 of 5147
Am I reading that right? 7,000 hours?!? ...and then replaced under warranty?!?!?!?!?!?!
post #4949 of 5147
Here is a photo with some fabric on the wall and the ceiling. I don't have a second screen yet. It was 78$ for the speaker grill cloth with tacks, and I had the black drapes already. The screenshot bellow needs color management to be viewed properly.

the bulb kept going. i had to open the iris more, but it was plenty of power.

i had an aftermarket bulb replacement warranty from mack in which they generally require you to send a 'broken' bulb back. i kept waiting for the bulb to go so i wouldn't have to fight, and finally just gave up. i had asked the warranty co before if i could replace at 5000hr and got a NO reply

so at 7000 hrs i sent screen shots, the benq manual and a pithy request and finally got approved

it didn't bother me to get more hours out of the bulb
i had a spare ready and swapped them a couple of times just to make sure i wasn't missing something, the old bulb was no diff, just a bit dimmer.



FYI: the projector gave out long before the bulb did. i needed two repairs before that 7000 hrs, one was nearly a complete replacement of the internal electronics. sadly these things are not made to last.
