Electrohome had a free replacement program which lasted for 2 years, so maybe someone switched it but usually no one did until a tube burned out (and sometimes not even after that) Big installations would just keep plugging in new tubes. |
I seem to remember there was an easy non-official checkpoint for the LVPS, maybe blue filament trimpot ok, white trim pot not ok?

I believe that information about the trimpot color to be false. I've had both blue and gray colors be bad.

Guys
The filament trimmers came in .67 watt and one watt ratings; it was the .67's that changed value over time, causing the voltage to drift higher and bake the filaments. One need only replace the .67 with a one watt device.

Hi guys,
This is a bit complicated for a newbie as me. But really interesting. I note each information ; it can be useful later!
I'm really impatient to test my new monster!

Hi guys..I pop in now and then to check on things without posting but this time I just hadda. Between this post and another one for the $135 G70 score I got a mega dose of nostalgia. It reminded me of when I got my first Marquee back in 2007 and how excited I was.
It's very comforting to see new adopters of crt even if they are 'ancient' and cost so much to ship but It's especially comforting to see there are still people in the world who will buy something that requires a brain to use instead of just a knife to open the packaging, and one finger to push the AutoMagic setup button.
Rock on New Dudes...Rock On.

Hi,
I'm excited because I'm going to discover something new. I hope to be capable of exploiting correctly this machine.
JustGreg is right. I had enough of too "plug and play" projectors and wanted to test CRT projectors for a long time, for their image but also because I want to learn to master them.
When I read to you, I'm a bit afraid because I've never made electronics... Mods seem to be necessary to bring a Marquee to its best. But I'm ready to try.
Thank you for your encouragements and your advices ; it's really kind. In France one is alone with his CRT projector!!!
Bye.

I wouldn't think it's worse than anywhere else... even here in Hungary I know about a dozen modern EM focusing machines and we are a small country, of course those guys don't show up here very often, but that doesn't mean they don't exist

Hi gjaky.
Perhaps you're right... But I tried to contact some crt machines owners on french forums without obtaining answers. The CRT projectors sections of main home-cinema forums are dead zones and it's really difficult to obtain some advices.

Again the same here, on most local ht forums the vast majority of the members can't even imagine that CRT projectors can display HD material...

Distance from other crt pj owners isn't as big a problem as you're leading yourself to believe. I think you're putting too much pressure on yourself and over thinking things. 
Most of us play at this hobby with only electronic links to other owners and mod guides but do just fine. Some have the money to spare and decide to have their setup professionally tweeked, but for the most part we go it alone. At the end of the day it all boils down to what looks good to YOU. If you think it looks great without spending hundreds of hours tweeking then that's all that matters.
This site has everything you need to make your Marquee rock n roll. Just roam around outside the forum page and check out the other parts of the site for manuals and mod procedures.

Bad news... I am disgusted...
The seller sent me an e-mail to explain me that he had decided to keep his Marquee and try to install it again.
I was so impatient and I'm really disappointed.
I don't know if I have to look for another CRT projector or try an installation with the BG808 (or the 6PG+) I already possess and which is not a bad machine.
I know there are much serious problems but I feel as a child who waited for a toy which he did not have...

Hold on for a minute! You have a BG808 and a 6PG+ too? Both are similar in performance to a Marquee 8500, in other word the Marquee wouldn't be waay much better than the barco or the nec.

wipe away those tears  the BG808 and 6PG+ are both fine machines, most people would be impossible to tell them apart from an 8500 picture quality wise
the BG808 will be a lot quieter and can scan higher, the 6PG+ will have more accurate colors. Or, you can combine them and put the PG lenses on the 808 (with adapter plates)

Yes, I have a BG808 with 5000h tubes and a NEC 6PG+ with 4000h tubes.
I was persuaded that the Marquee 8500 was better than the BG808 or the 6PG + and that's why I wanted to buy and install it...
Thanks for your informations.
So I have to find one of the better 8" (808s, 1208, Cine 8, 8500LC) or a 9" projector if I want to see a real difference?

The color filtering and LC optics are the things that makes the real difference between the machines, the rest only subtle difference. And of course if you want the sharpest 1080p image youronly way the 9" machines...

Ok. I'll try to install my BG808 and my 6PG+ correctly to make a live comparison.
Bye.

I disagree about the Barco 808 and Marquee 8500 having identical performance, The Marquee can run 1080P 60 hz and look damn nice, there is no way in hell a 808 will do that.
So for tubes and lenses to be more or less the same, but vidio chain in the marquee, and Bandwidth are way ahead.
+ you can get the Moome internal card for the Marquee who will give it a nice kick to.

Hi stridsvognen,
That's why I wanted to buy this cheap Marquee 8500 and why I was so disappointed...
It's very difficult to find a good CRT projector at a good price in France (as everywhere except perhaps in USA an Canada! ). And a BG808 is better than nothing...

I know, having the same issues in Belgium  A 9" EM machine almost never shows up and if it does it has burned tubes.

Or costs 4000-5000€ with 8000h+ tubes...
