Hi!
I have a Benq w10000 Full HD DLP now and are quite happy. I'm in use of a 105" screen but i miss the final touch made by a CRT. Which model provides a boost for me? I can imagine to give up to 2200 USD with good tubes

Thnx for reading :)

Welcome to the forum Atle...

The Ben Q model that you have mentioned above is a 1080p "capable" model, as far as how good it can resolve it....have no idea!

Being a (multiple) long time CRT owner (...among some bulb machines!), to me no there is no other technology that "cuts" it as nicely as a CRT would! (...at least not yet! ...short of spending mega bucks on a triple chip extra extra extra! ...even then it is a matter of "this gained/that lost"!)

IF you are looking for model numbers as to which one will do an admirable job of replacing it...I would have to say a decent 8 inch model and up!

Look into the marquee or a barco. (..Some Necs are great also, but some of the parts are made of "unobtanium"...not to mention other stuff!)

A Marquee 9500 will be ideal...but for the amount you mentioned you will probably have no choice but to go with a M8500.

Do you have a video processor?

You will also need an input card for the latest inputs...but that is not absolutely necessary. (...It all depends how it is set up.)

I would suggest a few more bucks to go with a M9500 ultra with a moome type hdmi card connected to a decent video processor,with some nicer lenses.

Once all is set up properly it will be hard to go back to the bulb machines again without knowing what you are sacrificing in the "drive" to use the latest tech!

So you might consider/wanna sell your Ben Q and add a few bucks for the (3) three devices that I mentioned above. (...assuming you still want this CRT conversion after all the stuff I mentioned above! ...which I feel anyone with a bulb machine should! but that is just me!)

Hope this was helpful in making your decision.

Atle some things to consider is fixed throw (NO zoom), a slightly softer but smoother and more film-like image, 160 pound weight, and if you like a VERY bright screen you will need a hi-power Da-lite 2.8 gain. I would try to see one locally before jumping in.
$2200. will get you a Marquee 8500 with perfect tubes, re-built electronics, and freight to you. You will still need some kind of HDMI transcoder.
Be very careful of an as-is 9500LC. A lot of them can have glycol leaks, dead tubes, HD10L (small screen) lenses and all MArquee's need a few technical bulletins before they're ready for prime time. Based on what i've seen really nice 9500's with no issues are running $3500. and up.

Martin, while I agree with your recommendation for a Marquee, the statement about NEC parts being unavailable is wrong.

G90 is the one with unavailable parts.


Enough NECs have been parted out, there are lots of bits. I can't think of anything offhand that is impossible to get.

I agree. WIth the exception of the CPU board in the G90, parts are plentiful out there, even for the Ampros.

Oh...except for 8" tubes.

Are they still making P16LJE tubes Curt?

Hello and what a good forum! :)

Thank you all for the good information. Is there a table for example Marquee and Barco where you see throwing distance? I can imagine to build a table in front of the couch which is above the projector. Or is it the ceiling set for the granting of sufficient distance for 105 "?

Assume 1.4x screen width to the lenses.


A CRT has to go on the ceiling - otherwise it occupies the prime seating spot.

It all depends on the lenses that are on the projector.
...for a plain vanilla marquee/barco CRT ...they usually come with HD8B lenses but most of us here replace them with color filtered hd144/145 nec type lenses!
Most projector use a usual throw distance is 1.5 X the width as measured to the lenses (this is a rule of tumb type thing and not in anyway accurate! ....but a good starting point!)

I am sure there is a chart flowing around some place in this forum...I have an excel on that I can attach here once I get home!


This is indeed an awesome forum!

Keep coming back!

Martin

ADDED LATER ON:

you can get the marquee manual that includes all the charts for that type of thing here:

there's also those brand new 8500 Longbows out there for $3K + shipping. They already have the slightly shorter throw HD-145's on them.

$3000 for an air coupled 8"er?

You can by a NEC PG for $300.

What's the real world difference?

One is brand new. ;)

The Longbows do 1080p@72 Hz with no problems, thats the difference. :D


Athanasios

Still air coupled.

Has someone fitted LUGs and HD-10s to one yet?

I will but that wont be for a long time, I want to use up the 8 inch tubes first.

Athanasios

I wouldn't exactly call it brand new. It is more NOS than NIB. It was made back in 2004.

Mark, these were those pjs that were picked up for around $1200 a couple of months ago.

Yeah, I know.

Why did Dragan say they are $3k?


I understand the electronics are the best ever. But they are still 8" air coupled.

They need LC optics at least.

Hello Mark

I agree about the G90 being made mostly of unobtanium!

As far as the NEC mention above...It just seemed to me that NEC had gotten through a lot of trouble making even the common components hard to identify! ...let alone find and replace! (using/changing numbers and using odd values!)

This is specially true of the power supplies! (There is a chip/resistor in there that goes bad quite often/commonly and is something that seems to have only been manufactured for NEC...I know that the majority of manufacturers do this to ensure that you can only deal with them for any future needs and torubles...but to me it seemed like NEC has made an art of it!)

Keep in mind that this is only my personal observations and that I am not an electronics whiz...(I know enough to be dangerous! ...and mostly to myself!)

So how many of these super 8 inchers were/are available?

I would like to at least update the boards in one of my nine inch marquees...

A few weeks ago I came across a Vision one for almost nothing...so as of last count I am somewhere in the (6) six in the 8 inchers and (3) three in the nines! (I am starting to run out of garage "real state"!)

...from here on only boards!!! (...I know I have said that before too, but can't help it! ...a Vision for less than the cost of buying used lenses from videogon!)


...that is a no brainer for me!

You make me jealous - 9"ers are rare here. Most are 1292's. If I want a 9"er I'd have to import...and that's expensive.

Ahh, yes, there was a NEC series with a faulty powersupply. The GP3000/5000 models.

They are old, really old. Think the generation before an ECP - over 20 years old.

When we say NEC, we mean XG and PG series. But I wouldn't touch a plain PG either these days, too old. PG Xtra is entry level.

Mark

...Sorry about the 9 inch shortage down under! (It must be tough! actually that would be the hardest for me...kinda like CRT hell!)

The power supply thingie in the NEC was from a PG series experience....I have only had one NEC and that was the one...but came across a few pg/xg power supplies that seem to have the same issues!

I live in LA so there are plenty of people that like to burn through money every time the neighbor down the street updates or whatever!

Needless to say there is no shortage of "obsolete" CRTs.

I have been concentrating my buying "power" on the 9 inchers lately...since I have more than enough 8xxx series.

I figure I should be set for the next decade at least. (Now only if I could be this wise and "forward looking" with some of the other aspects of my life/investments!)

If you are willing to pay shipping I will be more than happy to let you know of the next good buys!

Martin

Rubbish.

There's no major issue with PG or XG powersupplies.

But if one does break, just replace it with another.

Mark


Agreed...no major issue with the PS...just the way NEC does things!

I may be wrong on my conclusion! (...it's been known to happen from time to time! LOL)

"..if it breaks just replace with another oner" : that is exactly what I mean...replace with another ps that is as old and as prone to failure as the one before...maybe even more!

Now if only we/I were able to repair/modify without having to get a Ph.d in NEC "methods of hiding stuff", then yeah!?!?

These were my only NEC experiences and needless to say: they sucked!

...nice chatting with you in this fashion

Martin

Yeah, I know.
Why did Dragan say they are $3k? well ,.......because unless you can go back in time and bid on that auction it will cost you $3K to buy one off e-bay or from Bruce on Videogon.

I would like to at least update the boards in one of my nine inch marquees...Martin I can do that, very affordable too. I replace over 130 parts and gaurantee a noticeable improvement. Would also consider trading for something as well.;)

A CRT has to go on the ceiling - otherwise it occupies the prime seating spot.

Or you can do what I do. Mount the projector on a table, I use a picnic table, and do a zero angle tilt of the chassis for the lens. I then sit in a bean bag on the floor in front of the projector. It's like a mini-IMAX experience!

This also results in the best image quality too. None of that trapezoid shape garbage on the tube. You can make a perfect rectangle for each tube, with the same exact mm per line pair.

Draganm

...I will get in touch with you regarding those boards...It won't be until next month.

I still have to sort out my latest acquisitions!

Martin

Hi folks!
I had some offers but I can not answer pm's yet, sorry. I live on the other side of the ocean so I will be looking for one in the close by primarily :) But thank's for the offers! :)

Is 105" a good size for Barco 808s?

Is 105" a good size for Barco 808s?

...Atle...most CRT are good anywhere from 80 to 300" (At least that is what the specs say!)

A 104" screen is OK!

...the lenses dictate what would be acceptable and within reason.
...what lenses do you have on it?

If it is 105" diag it is on top of its game with 1~1.3 gain.
If you like it bright I would go smaller.

I don't remember the exact specs for your lenses...but for a 105 inch screen it is corret...if you wanted something like 150" then you might have to switch to gt17's.

1.3 gain is the sought after gain for CRTs...although some of us go much higher...but it takes a great deal of planning and setting up for it to be good and kosher!

...Needless to say that for a barco 808 gt17s would be overkill! (assuming you can even get them on there!)

They probably have the HD8Bs on them! (switching to the HD144/5s will help also...but no required unless you are trying to get that last ounce of performance out of it...)
BTW: do yours have the colored glycol in the tubes? if yes you will require the non color corrected HD14x's!

Martin

Hi! I'm back.
808s, unfortunately, was already sold. I found a G70 for quite a good price. Is there anything I should think about regarding this projector? They seem cruel image as the performance list. it has risen ca 2000h

I found a G70 for quite a good price. Is there anything I should think about regarding this projector? IMO, a second G70 for spare parts.

IMO, a second G70 for spare parts.

Well my Marquee had more problems than my G70 has ever had, I guess this means this rule should go for Marquee owners too?

:rolleyes: :)

With a Marquee you need a spare set of tubes in case it decides to cook the filaments ;)

And a spare HVPS; just because... ;)

Hi again!

Okay the swap is done! No turning back :D
I end up with a Sony G70 with some spare parts... Feels okay so far

I'm going to calebrate it now. But i need two auto memory blocks i discovered...

Is there a way to copy the work to the other one?
fH 33.7 khz
fV 60.0 hz (Blue Ray, dvd etc.)

fh 31.2 khz
fV 50 hz (for 720p games)

The input goes from a PS3 (1080i) --> HDMI ---> Moome IFB Slot B
So if there is someone out there who knows about the issue it would be nice with some tips :)

Atlemusic

Looks great!

I don't remember how the Sony's do it but with the marquees you can copy any of the blocks just by using the remote!

You are going to need to start from scratch...so no need to copy the old blocks anywhere! (assuming you are talking about doing just that!)

If you only have one source (The PS3) then no need to have multiple resolutions! (...again I am not sure if the PS3 switches outputs based on game mode!)

Martin

are those lenses actually sitting on the lens itself?

Hi Dragan!

No they stands on the plastic fix-spikes. The lenses go free under there :) are those lenses actually sitting on the lens itself?
